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.

Photogrammetry Measurement

Saturday, February 18th, 2017

Photogrammetry is a scientific method of measurements using photography. In essence, it is a measurement technology using the three-dimensional coordinates of points on an object are established through measurements taken using several (two to three) photographic images taken from different angles. The outcome is a map or drawing or a 3-dimensional model of an actual object or a scene. Most of the maps available today are creation of Photogrammetry or aerial photos taken using aircraft. Also, it can be considered as a reverse process which convert the 2-dimensional photograph to a 3-D image.

Frequency Measurement Based On Virtual Instrument Software System Design – The Electronics Industry

Monday, January 16th, 2017

Introduction Including ballistic radar speed, we must complete the projectile velocity measurements, Doppler velocimetry under the principle of the need for measuring the Doppler frequency estimation, while the frequency estimation is a classic signal parameter estimation problem. At home and abroad have made a lot of ways, the main and sometimes domain, spectral estimation method and time of a frequency domain, time domain method in which a number of cycles the main zero-crossing detection method and two, the main disadvantage is low accuracy; and Time frequency domain method of a main short time Fourier transform, Wigner distribution of a Virgin, while the calculation generally higher, difficult to complete real-time processing.

Making The Right Choice In Laser Measurement Devices

Sunday, November 13th, 2016

We rely on modern technology especially now that we are living in such an advanced world. Instruments like laser devices can give you very precise results when used to inspecting areas that are hard to measure accurately using other measuring devices.

Choosing the right laser device for measuring is important. It would save you time and money when you fully understand which device will best suit your needs. First off, you need to determine how you plan to use it. You should know if you are going to use it outside or inside. Determine the distance as well. For example, check if it is going to be used infrequently and in an environment that would note exceed 150 feet and mostly indoors.

Salinity Measurement

Saturday, September 17th, 2016

Measurement of the level of salinity in soy sauce, ketchup, dressing, soup, seasonings, pickled juices of vegetables, etc. is indispensible for quality control.  One of the key factors in producing these products is maintaining consistency between batches of their product for quality control and process control.  In order to keep this consistency the manufacture needs to test the product to determine the total concentration of salt.  Highly concentrated samples such as soy sauce need to be diluted so that the value reads lower than 6% before testing the sample.

Digital Multimeter – In-depth measurement of a device

Thursday, August 4th, 2016

The ultra modern Digital Multimeter is highly accurate. It is durable and consists of many more features as well than earlier multi meters. When testing with a digital multimeter, the user receives signals as numbers. It converts signals gained from the devices checked to voltages and convertes them to digits through electronic circuits based on pre-arranged software program. For this task, digital multimeter receives support from an inbuilt small computer.

People use Digital Mutimeters to measure voltage, current, resistant, short connections, as well as Transistor hFE values. For example, when there is to measure a potential voltage drop between two points, the two wires of the multimeter should be connected to the two points where the potential voltage drop is evident.

Electrical safety performance measurement instrument

Minimize measurement errors in RTD circuits
For a typical platinum resistor, the temperature range is -200˚C to 850˚C. The most common RTD is the Pt100, which has a resistance of 100 Ω at 0˚C. Generally, RTDs generate more stable and repeatable outputs compared to thermocouples and thermistors.
