4436535 42CP2 Original SENSOR. ZAX200/200-5G HITACHI Excavator Electric Parts

Pressure sensor is the most widely used kind of sensor, it is the detection of gas, liquid, solid and other materials between the general term of the influence force energy, also includes the measurement of pressure higher than the pressure gauge and the measurement of lower than the pressure gauge.

The resistivity changes and stress the mutual relationship between conductors called a semiconductor piezoresistive effect, the effect of mechanical quantity sensor called a piezoresistive type made of force sensor, it has two types, one kind is the semiconductor strain gauge sensor made of paste on the elastic element, called paste piezoresistive sensor type, another kind is the substrate of semiconductor material made of integrated circuit technology diffusion resistance, make the strain gauge sensor, with the whole of silicon substrate to form the same type called diffusion piezoresistive sensor. It is characterized by high sensitivity, high precision, small volume, light weight, high working frequency, simple structure, reliable operation and long service life.
