Air Flow Sensor, Etc. About Five Cars With Sensors

Friday, March 17th, 2017

Car Sensor A car computer system input devices, which run the car in various conditions of information, such as speed, temperature of various media, Engine Operating conditions, etc. into the computer lost the telecommunications number to the engine in top working condition. Many vehicle sensors to determine when the sensor malfunction should not only consider the sensor itself, but should consider the failure of the entire circuit. Therefore, to find fault, in addition to check the sensors, we should also check the wiring harness, connectors and sensors and electronic control unit of the circuit between. Now we come to know about the car’s main sensor.

The Pressure Sensor and Its Effect on Quality of Life

Tuesday, October 25th, 2016

A pressure sensor is a device used to give engineers an early warning of rising or falling pressure in a machine or working device. Changes in pressure can signal an impending problem or breakdown. This can affect not only the machine, but also the process in which the machine is engaged. Pressure sensors belong to a class of accessories that greatly affect the smooth operation of manufacturing processes.

Typically sensors measure liquids and gasses as they expand or contract. A sensor will give a reading of the force being exerted by a container to prevent the liquid or gas from expanding. The sensor acts as a transducer emitting a signal of the force being exerted. In most cases the signal is electrical in nature.

Linear Guide Ntc Temperature Sensor – Temperature Sensor – Electronics Industry – Flanged Ball Valve

Wednesday, July 20th, 2016

Thermal component, it is actually a linear temperature – voltage conversion device, that is in communication with operating current (100uA) under the conditions of the voltage component changes linearly with temperature in order to achieve the non-electricity to power linear transformation.

2. Linear NTC temperature Sensor What are the main features?
This temperature sensor whose main characteristic is the temperature in the working temperature range – voltage relationship as a straight line, which for the secondary development of temperature measurement, temperature control circuit design, without linearization, temperature measurement can be completed or temperature control circuit, thereby simplifying the design and debug instrument.

The Development Trend Of Humidity Sensor – Gas Compressor Manufacturer – Oilfield Auxiliary

Thursday, May 28th, 2015

In the industrial and agricultural production, weather, environmental protection, national defense, scientific research, aerospace and other departments are often required to measure and control humidity. However, in conventional environmental parameters, the humidity is the most difficult to accurately measure a parameter. With the dry and wet bulb hygrometer or a hair hygrometer to measure humidity, the method has long been unable to meet the needs of the development of modern science and technology. This is because the measurement of humidity than the measurement of complex multi-temperature, the temperature is measured is an independent, while the humidity is affected by other factors (atmospheric pressure, temperature) effects.
In addition, the calibration of humidity is also a problem. Production abroad humidity calibration equipment prices are very expensive.
In recent years, the humidity sensor research and development at home and abroad have made great strides. Humidity sensor is moving from simple humidity sensor to the integrated, intelligent, multi-parameter detection of the direction of rapid development, in order to develop a new generation of humidity / temperature measurement and control system has created favorable conditions for humidity measurement techniques will also be raised to a new level.
The characteristics of humidity sensor
Humidity sensor is the simplest humidity sensor. Humidity sensor are mainly resistive, capacitive two broad categories.
a humidity sensitive resistor
Humidity resistance is characterized by the substrate covered by a layer of wet material with a sense of the film, when the air in the water vapor adsorbed on a sense of the wet membrane, the components of the resistivity and resistance values are changed to use this feature Humidity can be measured. Many different types of humidity resistance, such as metal oxide humidity resistance, humidity resistance of silicon, ceramic humidity resistance and so on. Humidity resistance has the advantage of high sensitivity, the main drawback is that linearity and interchangeability of products poor.
b Humidity Capacitance
Humidity capacitors are generally made with the polymer film capacitors, polymer materials commonly used in polystyrene, polyimide, cellulose acetate, etc. butyricum. When the ambient humidity changes, the capacitance of the dielectric constant humidity changes, so that it is also a change in capacitance, its capacitance is proportional to the change in relative humidity. The main advantage of capacitive humidity sensor with high sensitivity and product interchangeability is good, fast response, a small amount of moisture lag, easy to manufacture, easy to achieve miniaturization and integration, and its accuracy in general is lower than the humidity sensitive resistor. The main production abroad humidity capacitor manufacturers are Humirel company, Philips Company, Siemens Corporation. To Humirel produced SH1100-type humidity sensor capacitor, for example, the measurement range is (1% ~ 99%) RH, at 55% RH when the electrical capacity of 180pF (typical value). When the relative humidity from 0 to 100%, the changes in capacitance range is 163pF ~ 202pF. The temperature coefficient of 0.04pF / , humidity hysteresis amount of 1.5%, response time of 5s.
In addition to resistive, capacitive humidity sensor, there are ionic-type humidity sensor, weight-type humidity sensor (with a sense of the changes in the weight of wet film to change the oscillation frequency), light intensity-type humidity sensor, SAW humidity sensor and so on.
Humidity sensor linearity and anti-pollution poor in the detection of ambient humidity, the humidity sensor to a long-term exposure to the environment under test, it is easily affected by pollution, measurement accuracy and long-term stability.

A Short Introduction To Temperature Sensor

Monday, April 13th, 2015

To put it simply, a temperature sensor can be considered as the most important part of a temperature monitoring system. It is used to gather data related to temperature fluctuations, which is then converted to a form easily understandable by humans. Data from the source or  system is converted to a readable format and an alarm system is activated automatically, which informs the observer about undesired changes and fluctuations.
