Stainless Steel Pressure Sensor
Description of stainless steel pressure sensor
UPX22 all-welded pressure sensor is constructed by welding general pressure sensor UPX19 into
pressure port with standard or specific thread. This structure avoids the hidden trouble or incompetability caused to O-ring in bad conditions. The sensor back end (electrical side) is suppled with M25*1 male thread, it will be easy for use to make transmitter with this design.
UPX22 all-welded pressure sensor can be customized as special requests.
UPX22 pressure sensor is widely used in petroleum industry, chemical industry, process control, hydraulic system, pressure examination measuring instruments, pressure calibration instruments, refrigeration plant and air-conditioning system as well as aviation navigation examination etc.
