HR3288 HART Smart Pressure Transmitter

The HR3288 protocol Smart Pressure Transmitter is a high-precision, high-stability, multi-parameter, four and a half digits LCD display  for intelligent pressure measurement products.  It conforms to HART protocol. The users could manage, adjust or monitor the process variables by HART communicator, and it could also be configurated by key-press at local working place.
The pressure transmitter uses the most advanced digital technique, temperature compensation, linearity correction and reliable ex-proof construction for production. pressure transmitter has high accuracy, wider temperature compensation range and standard signal output to measure flow pressure precisely. 

The product works in a two-wire mode and can be directly replaced analog two-wire 4mA-20mA DC output transmitter. Digital communication with manual operator. Electromagnetic radiation fits IEC801 standard.
