Rectified DC power supply system sensor design elements

DC power meter management control in electrolysis industry has a pivotal position , it is one of the main technical assessment indicators tapping the potential of business efficiency , but also to protect one regulating rectifier power source running smoothly , so that the DC sensor power rectifier system accurate, stable and reliable is very important.As we all know , the current domestic market popular DC current sensors and closed-loop two separate forms , and the two forms of Car Temperature Sensor measurement accuracy has its theoretical basis , are based on the current Hall elements collected by the air gap in the magnetic circuit and the magnetic field is proportional to the voltage signal converted over , under current law the theoretical framework of the whole design .Factors affecting the DC sensor measurement accuracy depends largely on the choice of the core and the Hall device , as much as possible to ensure the performance of magnetic materials , magnetic materials forming around them a special process to deal with the structure , making the magnetic material permeability is improved, so that Coolant Temperature Sensor has been effectively guaranteed linearity .

What is the characteristics of strain pressure sensor

Pressure sensor is a kind of commonly used sensors, widely used in medical, ships, aerospace, petrochemical, machine tools and other industries. Pressure sensors need to know when in use of knowledge is also a lot of, among them the characteristics of strain pressure sensor for users is also a need to understand, here is for everyone to introduce what is the characteristics of strain pressure Automobile Temperature Sensor.The measuring range of the pressure sensor is twice as big as the inductive sensor, it can not only detect metal target, but also detect dielectric, such as paper, glass, wood and plastics, and even can be detected by a wall or paper shell. Because the human body in low frequency is equal to the electrical conductor, thus can be used for the quiver measurement and alarm.
In the measurement of strain, the strain gauges can be on the component, but if the measuring force, pressure, acceleration, should first change the physical quantity measuring strain, and strain gage, a conversion process more than direct measurement, to complete the conversion process is usually called the original as the elastic elements, therefore, the strain Camshaft Position Sensor is usually made of elastic sensitive components and the strain gauge is composed of two parts.
Elastic sensitive element is a core component of sensor, elastic component of elastic energy storage requirements high, usually expressed as elastic material storage and deformation work without permanent deformation. Pressure sensor has good mechanical processing and heat treatment performance, has high compressive strength. Influence of temperature and other characteristics, correct choice of elastic sensitive components and strain gauge bridge is an important way to improve the strain sensor:
1 measuring range, high precision, the force sensor can measure the force of 0.01--1000000N, the accuracy can reach more than 0.05%FS; the pressure sensor can measure the pressure of 0.1-1000000, the accuracy can reach 0.1%FS.
2, stable and reliable performance, long service life, such as weighing type mechanical lever, the lever, the knife edge part of mutual friction loss and deformation, we want to maintain its accuracy is quite difficult, using resistance strain weighing sensor made of electronic pump, truck scale, railway scale, long-term stable operation in harsh environmental conditions.
3, the frequency response characteristic of excellent. Pressure sensors of resistance strain gauge response time is 0.01MS, the dynamic process of semiconductor strain gauge can reach strain sensor if 0.001MS can take measures in the elastic component is constitute by them can be measured in tens or even hundreds of Hertz hz.
