Strain Gauge Pressure Sensor
Brand: Xi'an UTOP Measurement Instrument Co, LtdBased on metal foil strain gauge technology, the sensing elements of UPX-7 series pressure sensors are strain gauges, these strain gauges form a Wheatstone bridge on back of the diaphragm to sensing the deformation of the diaphragm, this deformation 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 uses unique sealing method between the diaphragm and the connector, so as to ensure the sealing reliability, and also ensure the diaphragm performance. This sensor is widely used in food, medicine and beverage industries.
Features- 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
