Signal acquisition and processing of pressure sensors
Signal acquisition and processing of pressure sensors In the field of modern industrial control and system monitoring, it is usually necessary to monitor and measure pressure and weight. Pressure measurement is particularly important as it can be directly used to measure fluids, heights, and othe...Read more -
Working principle of oxygen sensor
Under certain conditions, a potential difference is generated by utilizing the oxygen concentration difference between the inside and outside of zirconia, and the larger the concentration difference, the greater the potential difference. The oxygen content in the atmosphere is 21%, and the exhaus...Read more -
Precautions for using pressure sensors
During the use of pressure sensors, we need to pay attention to the following matters 1. Prevent the transmitter from coming into contact with corrosive or overheated media; 2. Prevent sediment from settling inside the conduit; 3. When measuring liquid pressure, the pressure tap should be opened ...Read more -
Reasons for pressure sensor error
Do you know the reasons that affect the total error of pressure sensors? When analyzing the total error of pressure sensors, the first step is to consider the source of each error, analyze the factors that cause these errors, and then find ways to reduce these errors and improve the overall perfo...Read more -
Innovative application of pressure sensors in automobiles2
6. Check the pressure of key fluids The most common use of electronic pressure sensors may be to measure the pressure of critical fluids in vehicles, such as engine oil, transmission and gearbox oil, as well as hydraulic oil in braking systems, cooling systems, and fuel systems. The partial struc...Read more -
Innovative application of pressure sensors in automobiles
If pressure sensors were not used in modern cars, our driving experience would be much worse. In fact, most critical systems in vehicles rely on pressure sensors to measure and monitor key parameters to improve our driving experience, enhance safety, and reduce pollution. In recent years, benefit...Read more -
Output characteristics of intake pressure sensor
The output characteristics of the intake pressure sensor: In electronic fuel injection engines, the use of an intake pressure sensor to detect the intake volume is called a D-type injection system (speed density type). The intake pressure sensor does not directly detect the intake air volume like...Read more -
Pressure sensor precautions
Firstly, let’s understand the structure and function of conventional pressure transmitters. A pressure transmitter is mainly composed of three parts: a pressure sensor, a measurement conversion circuit, and a process connection component. Its function is to convert physical pressure paramet...Read more -
Error compensation of pressure sensor
Reasonable error compensation of pressure sensors is the key to their application. Pressure sensors mainly have sensitivity error, offset error, hysteresis error, and linear error. This article will introduce the mechanisms of these four errors and their impact on test results. At the same time, ...Read more -
The difference between a pressure sensor, a pressure relay, and a pressure switch
The pressure sensor is composed of a varistor and a conversion circuit, which uses the pressure of the measured medium to act on the varistor to produce a small change in current or voltage output. Sensors often need to be used in conjunction with external amplification circuits to complete proce...Read more -
Selection and installation of pressure switch for injection molding machine
Pressure sensors can be installed in the nozzle, hot runner system, cold runner system, and mold cavity of injection molding machines. They can measure the plastic pressure between the nozzle and the mold cavity during the injection molding, filling, holding, and cooling processes. This data can ...Read more -
