HR3051-LD Differential Pressure Remote Transmitter

overview

.The diaphragm of the differential pressure remote transmitter is used for preventing the medium in the pipeline from directly entering the pressure sensor component of the differential pressure transmitter, and the pressure is transmitted between the transmitter and the filling liquid such as silicone oil.

.The HR3051-LD Differential Pressure Transmitter is used for measuring the level, density, pressure, and flow of liquids, gases, or vapors and then convert it to a 4-20mA DC HART current signal output. The HR3051-LD can also communicate with the RST375 handheld terminal or the RSM100 Modem for parameter setting, process monitoring, and more. The measuring range of the HR3051-LD differential pressure remote transmitter (when not moved) is 0-1kPa~2MPa, and the rated pressure of the remote flange is: 1.6/4MPa, 6.4MPa, 10MPa, 150psi, 300psi or 600psi.

Operating principle

The HR3051-LD differential pressure remote transmitter consists of a HR3051-DP differential pressure transmitter and a welded remote flange with a capillary. Its working principle is the same as HR3051-DP type differential pressure transmitter (see HR3051-DP type differential pressure transmitter technical specification), but the pressure transmission path is slightly different: the pressure acting on the remote flange side is firstly The diaphragm and filling liquid on the remote flange are passed through the capillary tube and finally reach the corresponding positive and negative sides of the measuring sensor.
