Remote Differential Pressure Transmitter

Brand: Xi'an UTOP Measurement Instrument Co, Ltd

This Remote Differential Pressure Transmitter has strong adaptability and high reliability, and also has good anti-interference ability and zero stability.

Its accuracy reaches 0.1% FS. UIB3351 can be made with HART Protocol communication, can be communicated with many hand-held communicator like HK- 375 & Rosemount 275 etc.

UIB3351 Pressure Transmitter 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.
Features
  • Have strong self-diagnostic capability
  • Wide ranges from 0~100 Pa to 42 MPa
  • Accuracy better than 0.1% FS or 0.2% FS, rangeability 15:1
  • Zero and span adjustment without mutual influence
  • Have prefect remote setting, local setting as well as adjustment function
  • 2-wire system, Hart Protocol
  • Use digital compensation technology to compensate for temperature and system pressure error
  • Good stability, high accuracy, adjustable damping, strong unidirectional overload capacity
  • Optional of diaphragm material (contact medium), explosion-proof
