Power sector demand for electrical measuring instrument products about the market demand for electrical instrumentation products 90%, and the demand for electrical instrumentation products play a decisive role. The remaining 10% of the demand from other areas of national economic construction.

Users of major technical standards of products:
Electrical Instrumentation Industry main characteristics of high technology, integrated development of various techniques, sensitive to new technology, product update cycle is short, and thus electrical instrumentation industry is facing more opportunities and greater challenges. Electrical Instrument of new products are the product level users demand more and more.

(1) energy measurement instrumentation and systems: the current user requirements of 86 series-based induction meter,
Electronic Energy Meter (mainly single-phase) of the demand rose rapidly. “15” period, the user needs the induction meter will gradually transition to the 25 to 30 years, life expectancy, more than 6 times the overload capacity; electronic energy meter demand will be further strengthened, and single-phase electronic power meter, power card Prepaid Electronic Energy Meter, Three-phase electronic multi-function power meters and multi-rate watt-hour meter will be the main need to target. High-precision power meter is mainly used in crossing point or network port point, there is a demand, but because of its high technology content, now mostly imported from abroad; centralized automatic meter reading system to implement the far-range household electricity meter reading is to develop trends, the demand for automatic meter reading system will also increase.

Concern: The Virtual Test And Measurement Instruments Become The Mainstream Industry – Virtual

Sunday, May 21st, 2017

Since the twentieth century, since the mid-eighties, virtual instrument technology has been combined with a modular hardware, development software and PC technology, which enables users to create custom software instruments. Software-defined functions than the vendor-defined way of desktop devices for greater flexibility, and because PC-based technology, they are able to achieve faster advanced features.

Now in test applications using virtual instrument technology has become mainstream. Most testing industry has accepted the concept of virtual instrumentation, or a preference for virtual instrumentation. For example, a representative of the U.S. military, though not the leader in technology trends, but also in widespread use of virtual instrumentation. As the world’s largest ATE (Automated Test Equipment) independent users, the U.S. Department of Defense has in their comprehensive instrument to promote the use of the concept of software-based devices. Report to Congress, the Defense Ministry said: “In the development of integrated devices, with the commercialization of new technologies in real time to configure the instrument to achieve a variety of testing capabilities …… a single integrated device can replace multiple independent function of the instrument, thus reducing the volume of logistical equipment and to address the problem of aging equipment. “[February 2002, the Ministry of Defence Office of the technical improvement report to Congress]. Integrated instrument and virtual instrument technology with commercial hardware and software processing features, these two together can create user-defined instrument.

Present, thousands of major companies have started using virtual instrumentation. Detection only in the production, like Lexmark, Motorola, Delphi, ABB and Philips have these industry leaders in key projects, large-scale product test applications using virtual instrumentation hardware and software. In the industrial field, the virtual instrument technology has been used for automation of oil drilling and refining, production of machine control, and even nuclear reactor control.

The problems of traditional instruments and innovators
ClaytonChristensen of the same name as described in the book, traditional instruments will suffer in the meantime, “innovators of the problem.” Christensen is described this phenomenon: the new breakthrough technology will change the market outlook and ultimately overthrow the market leader position. In fact, Christensen that the market leader in new technologies is very difficult to reverse after leading the market up. In test and measurement field, the traditional instruments by using the existing structure to improve the measurement performance and continuous innovation along this direction. In the early days of virtual instrumentation, measurement of performance because of its relatively low, so in this case, the breakthrough technology with traditional instrumentation, and without much threat, so they largely ignored the virtual instrument technology existence. However, the twentieth century, the late eighties and early nineties, the virtual instrument technology been applied to measure the need for flexibility, which are applied by conventional methods can not be achieved. To the late nineties and the twenty-first century, with the PC processor and the commercialization of semiconductor performance and further improve the accuracy of the virtual instrument technology, measuring performance has improved much more than the original. Now, the virtual instrument technology and performance of traditional instruments of measurement equal to or exceed them, but also has a higher data rate, flexibility, scalability, and lower system cost.

In the consumer goods market in order to prove the “innovators problems” this principle, we can compare MP3 and traditional broadcast media such as CD. The beginning of the traditional audio equipment manufacturers are not aware of the threat of MP3 player?? After all, MP3 sound quality decreased, and when you need to play PC and specialized software. On the other hand, CD player, is easy to use and have a special user interface (buttons and knobs). However, due to sharing of MP3 and portable with easy-to-edge, so despite its shortcomings, is still in the early birth praised by some users. Over time, MP3 quality has been acceptable and MP3 player software has also been a great development. MP3 has become mainstream now, and the traditional audio recording and playback industry caused a great threat. Although many traditional player manufacturers through the development of the final player with MP3 function to shift to this breakthrough technology (Sony recently introduced a MP3Walkman), but the new market has been the first introduction of MP3 technology, led the company. For example, Apple has captured the hard disk based music player sales, 82% [NPD, 2004 8 months].

In test and measurement market, an industry leader Agilent has also introduced the concept of virtual instrumentation. For example, Agilent recently introduced products include a set of Ethernet-based “integrated equipment” and is compatible with PXI arbitrary waveform generator, and the industry-standard PXI is the platform for virtual instrumentation. Agilent’s JohnStratton also recently expressed support for software-defined and comprehensive equipment concept: “and the current standard use of rack solutions, another option is to use the integrated devices. Integrated device uses software algorithms and hardware modules to replace the separate The test unit. “[the military and aerospace electronics, June 2004]. In a recent investor conference, the Agilent’s chief operating officer BillSullivan proposed, “to use the software-based modular instrumentation configuration, allowing users to easily configure and re-use to repeat, it will be testing and measuring the direction of future development . “

PC performance and reduce cost innovation
In the past two decades, PC’s performance has improved 10,000-fold, not to any other business of technology there had been such a high performance growth. As the use of virtual instrumentation for measurement of PC processors, each with the emergence of a new generation of PC processors, the use of virtual instrument technology new applications can be achieved. For example, the current 3GHzPC can be used to carry out complex analysis of frequency domain and modulation for use in communications test applications. Using the 1990 PC (Intel386/16), 65,000 points of the FFT (Fast Fourier Transform for spectral analysis of the basic measurement) needs 1100 seconds. And now the P4 3.4GHz computer using the FFT to achieve the same offer just 0.8 seconds [Ffbench, JohnWalker].

At the same time, hard disk, display, and bus bandwidth has a similar performance improvement. A new generation of high-speed PC bus bandwidth can provide up to PCIExpress 3.2GBytes / s, which can be used PC architecture to achieve high bandwidth measurements. Some companies claim to be giving way to high-speed internal bus such as Ethernet and

The Different Types Of Financial Instruments

Sunday, February 26th, 2017

The first type of financial instrument is the treasury bill. Treasury bills or T-bills are direct obligations of the US government and thus are considered to have no default risk. They are sold weekly and have maturities that range from three months to one year. Financial institutions, corporations and individuals buy the securities for their liquidity and safety of principal.

The second type of financial instrument is known as the negotiable certificates of deposit. Negotiable certificates of deposit or otherwise known as NCDs are large denomination time deposits of the nations largest commercial banks. Unlike other time deposits of most commercial banks, negotiable certificates of deposit may be sold in the secondary market before their maturity. Only a handful of banks sell the negotiable certificates of deposit or engage in best forex trading markets.

The third type of financial instrument is known as commercial paper. Commercial paper is the unsecured promissory note otherwise known as the IOU of a large business. Commercial paper typically has maturities ranging from a few days to 120 days and do not have an active secondary market. Corporations and finance companies are major issuers of commercial paper.

The last type of financial instrument are generally known as federal funds. Technically, federal funds are bank deposits held with the federal reserve bank. Banks with deposits in excess of required reserves may land of those excess reserves called Fed funds to other banks. The banks have acquired the Fed funds they use them to cover a deficit reserve position bar can use the funds to make consumer or business loans. The Fed funds loans are typically for one day or for over a weekend. At a more practical level you may think of the Fed funds market as the market in which banks make short-term unsecured loans to one another and the Fed funds interest rate is the intra-bank lending rate. Though somewhat confusing the Fed funds market has no connection with U.S. Treasury but it does offer some of the best forex trading tips. While a lot of these are out of the reach of the average investor knowing about them can help understand the fundamentals that drive the market.

Instruments and Methods for Pressure and Flow Calibration

Friday, June 19th, 2015

Pressure is an important process variable because it sets critical conditions for boiling, chemical reactions, distillation, extrusion, vacuuming, and conditioning of air. Incorrect pressure or flow rate can cause major safety, quality, and productivity problems. Very high pressure or flow rate inside a sealed environment can also cause an explosion. In order to ensure that plants operate efficiently and safely, periodic calibration of pressure, level, and flow instruments is required.

Many factories and metrology laboratories use various pressure and flow-meter calibration instruments. This high-accuracy equipment is used to calibrate industrial devices like pressure transducers, pressure gauges, and transmitters, as well as instruments that measure and control flow.

Some of the important types of devices used with pressure calibrators are:

1) Pressure gauges: They are instruments used to measure pressure in liquids and gases. Some of the commonly used pressure gauges are glycerin gauges, electric contact gauges, differential gauges, test gauges and capsule gauges. These are usually used in commercial production plants.

2) Calibration standard pressure sensors: These pressure sensors, usually consisting of differential pressure manometers, gauges, pressure controller, transmitters, and vacuum gauges are very precise and are sometimes used in calibration standard labs for secondary reference.

3) Pneumatic calibration hand pumps: These pressure calibrators manually produce air pressure set points. Then, these are used to calibrate pressure equipment with the help of a pressure indicator.

4) Pressure calibrators utilizing electrical measurement: These measure electrical current as well as voltage in order to show the output signal produced by a pressure transducer.

5) Digital test gauges: These gauges are installed on both hydraulic and pneumatic calibration hand pumps to determine pressures with precision.

6) Precision manometers: These pressure calibrators are handheld instruments, which provide a selection of pressure units. They are powered by batteries.

7) High pressure calibration hand pumps: These instruments produce pressure in order to calibrate a test gauge or connect to an indicator.

For any transducers or measurement systems, which provide information on the amount of material transferred in a given time, flow meter calibration is necessary. In flow-meter calibration, measurements usually occur in units of mass per unit time (gravimetric measurement) or volume per unit time (volumetric measurement). These two types of measurements relate to one another by the density (mass per unit volume) of the flowing material. This third method is called comparison measurement.

DH Instruments provides superior calibration solution through innovative technology, first rate service and uncompromising metrological integrity. It is a leading manufacturer of pressure calibrator, pressure monitor, dead weight tester, flow controller, flow calibrator, sonic nozzle and many other pressure & flow calibration equipments.
