Description
Product Features
The inductive sensors produced by Zhongyuan Gauge have a complete range of measurement range and high measurement accuracy. They are not only suitable for product inspection in production workshops, but also suitable for precision testing occasions such as metering rooms. At present, the sensor of Zhongyuan gauge has been widely used in many industries of industrial production at home and abroad to precisely measure the size, shape and position error of the measured piece.
The main components of the inductive sensor include measuring rod, magnetic core, coil, etc. During detection, the change of the displacement of the measured piece changes the relative position of the magnetic core and the coil through the measuring rod, thereby changing the inductance of the coil. The electrical part matched with the sensor amplifies and shapes the changing signal after processing, and displays it in the form of analog signal or digital signal.
Inductive sensors are divided into two types: differential inductance and differential transformer in principle. From the measuring rod movement mode, they are divided into two types: elastic type and pneumatic propulsion type. From the structure, they are divided into rolling guide rail type, sliding guide rail type and lever type. Most of the sensors use rolling guide spring return structure, we call this form the basic type. The pneumatic propulsion sensor adopts filtered and stabilized clean gas of 0.05 ~ 0.1MPa to measure the measuring rod after being pushed out. The measuring rod retracts when the gas stops, which is convenient for taking and placing workpieces.
