LFT720 Monocrystalline Silicon Differential Pressure Transmitter with Flange

LFT720 flange-mounted transmitter consists of the LFT710 Differential Pressure Transmitter and a welded level flange. The flange and the sensor are filled with silicone oil to transfer the pressure, avoiding the measurement influence of the measured medium through the pilot tube. The Influence on the measurement caused by the measured medium passing through the pilot tube includes crystalline solidification vaporisation (boiling), condensation, fractionation (heavy change), etc. lt is used to measure the pressure of liquids, gases or steams and then convert it into a 4-20mA signal. The measurement principle is the same as LFT710 DP Transmitter. The only difference lies in the pressure transfer route, pressure is firstly transmitted through the diaphragm of the level flange and the filled oil, then through the transmitter body and finally reach the measuring sensor.
