BLR-42 pull-type load sensors

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.
