Applications of pressure transmitter

·Pump and compressor

·Commercail air conditioning unit

·Automatic testing system

·Pneumatic system


Introduction of pressure transmitter

PT03 pressure transmitter made by ORR’s own pressure sensor core as sensor sensitive element. Pressure transmitter can be transferred liquid or gas pressure into the various standard analog output signal 4~20mA, 0~5VDC, 0~10VDC, 0.5~4.5VDC. Transmitter strictly proceed by high-low temperature calibrated and endurance test with tough structure. It is proved that  PT03 product works well under severe environment, PT03 product has shared a reliable performance and service to some very famous customer such as Carrier, LG and SANY Group etc.The product is widely used for pump, compressor, commercial air conditioning and pneumatic system.
