Capacitive Differential Pressure Transmitter
Brand: Xi'an UTOP Measurement Instrument Co, LtdUIB3351 Capacitive Differential Pressure Transmitters are suitable for the measurement of flow, level and pressure (differential pressure, gauge pressure and absolute pressure), this product has strong adaptability and high reliability, and also has good anti-interference ability and zero stability.
Its accuracy reaches 0.1%FS. 3351 can be made with HART Protocol communication, can be communicated with many hand-held communicator like HK- 375 & Rosemount 275 etc.
UIB3351 Capacitive Differential Pressure Transmitters is composed of pressure sensor and PCB.
The pressure sensor includes sensing element, EEPROM and other parts; PCB includes micro processor, digital/analogue converter, digital communication and memory EEPROM etc, to complete the conversion from pressure signal to 4~20 mA DC signal.
