Product Introduction
The important role of sensors in modern science and technology have been fully recognized, it is an important means of technology is indispensable is to achieve automatic control of the test and the most important part.
Sensor is home to one of the widely used, which is based on resistance strain gauges for the conversion element, such as the non-power: force, pressure, displacement, acceleration, torque and other parameters is converted to electricity, has the following characteristics:
S-type shape
Simple structure
High cost performance
High precision, wide measuring range
Frequency response is good
Simple structure, small size, light weight
It can operate in the harsh environment of high temperature, low temperature, high pressure, strong vibrations, strong magnetic field and nuclear radiation.
