RDLY is a series of pressure transmitters through silicone oil pressure sensor, the signal is then converted to Hart protocol and the circuit converts to a 4~20mA current signal. The characteristics of this transmitter line are high precision, stable operation, good interference resistance, wide measuring pressure range, easy calibration or change of measuring range, compact size, light weight and easy installation.
Explosion-free pressure sensor application
Sensors are applied a lot on ships such as: Cargo tunnel pressure alarm system, pump pressure alarm system, pipeline pressure alarm system, cargo tunnel level measuring system and water level system to penetrate the cargo tunnel.
