HR3051-LT Differential Pressure Level Transmitter

overview

The diaphragm of the differential pressure level transmitter is used to prevent the medium in the pipeline from directly entering the pressure sensor component of the differential pressure transmitter. It uses a filling fluid such as silicone oil to transmit pressure between the transmitters.

The HR3051-LT differential pressure level transmitter be used for measuring 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 RP2001 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-LT differential pressure level transmitter (when not moved) is 0-1kPa~2MPa, and the rated pressure of the liquid level flange is: 1.6/4MPa, 6.4MPa, 10MPa, 150psi, 300psi or 600psi.

Working principle and structure

The HR3051-LT differential pressure level transmitter consists of a HR3051-DP differential pressure transmitter and a soldered liquid level flange. Its working principle is the same as HR3051-DP type differential pressure transmitter (see HR3051-DP type differential pressure transmitter technical specification), except that the pressure transmission path on the positive pressure side is slightly different: the pressure acting on the high pressure side is firstly The diaphragm and filling liquid on the liquid level flange pass through the transmitter body and finally reach the high voltage side of the measuring sensor.
