Flush Diaphragm Pressure Transmitter
Description of flush diaphragm pressure transmitter
UPB2 flush diaphragm pressure transmitter uses piezoresistive silicon chip as sensing element. UPB2 has clamping type, G1/2 thread type, and flange type for options. Its output signal can be made standard voltage output signal or current output signal.
UPB2 flush diaphragm pressure transmitter is made with flush membrane structure, it has good ability on preventing fouling, crystallization and jamming of thick liquids.
UPB2 flush diaphragm pressure transmitter is widely used in food, medicine, health and wine industry etc.
