HR3051-DP Differential Pressure Transmitter-HighReach

HR3051-DP Differential Pressure Transmitter

The HR3051-DP differential pressure transmitter measures the level density pressure and flow of a liquid gas or vapor and converts it into a 4-20 mA DC HART current signal output. The HR3051-DP can also communicate with the RST375 handheld terminal or the RSM100 Modem for parameter setting process monitoring and more.

Standard Specification
(Standard zero as the reference calibration range Stainless steel 316L diaphragm filling liquid is silicone oil.)

It can be arbitrarily adjusted within the upper and lower limits of the range.

Zero and span can be adjusted to any value within the measurement range in the table

The change in mounting position parallel to the diaphragm surface does not cause zero drift

2-wire system 4 to 20mADC optional HART output digital communication selectable linear or square root output
