LR3051DP Double Flange Intelligent Remote Differential Pressure Transmitter

Remote transmission pressurePressure transmitter manufacturerThe remote transmission device is used to prevent the medium in the pipeline from directly entering the pressure sensor component in the transmitter. It is connected to the transmitter through a capillary tube filled with fluid.

LR3051DP remote differential pressure transmitter is used to measure the liquid level, flow rate, and pressure of liquids, gases, or vapors, and then convert them into 4-20mA Dc signal output. The LR305lDP intelligent remote differential pressure transmitter can communicate with the HART controller for setting and monitoring.
