Strain Gauge Pressure Sensor
Description of strain gauge pressure sensor
Based on metal foil strain gauge technology, the sensing elements of UPX7-b is strain gauge, the strain gauge form a Wheatstone bridge on back of the diaphragm to sensing the deformation of the diaphragm, it results from the pressure which act vertically to the diaphragm.
UPX7-b strain gauge pressure sensor is made with flush diaphragm. Its performance and principle are similar to UPX7-a. By using integrated structure without O-ring or welding, its measuring range can reach 6000bar.
UPX7-b strain gauge sensor uses welding as sealing method, and widely used in food, medicine and beverage industries.
Features of strain gauge pressure sensor
◇High accuracy, high performance
◇Suitable for middle and high pressure measurement
◇Isolated structure, suitable for many kinds of pressure medium
◇Anti-corrosive, anti-attrition, anti-impact
◇Pressure port has cavity type and flush diaphragm
