LFT720B Double Flange-mounted Differential Pressure Transmitter is composed of the LFT710 Differential Pressure Transmitter and a small welded remote flange with a capillary tube. Between the flange and the sensor, silicon oil and other filing fluids are used to transmit pressure, to prevent the measured medium from passing through the impulse pipe. Which will impact the measurement. The impact of the measured medium pass through the impulse pipe includes crystallization, solidification vaporization (boiling), condensation fractionation (severe change) and etc. The Transmitter is used to measure the liquid level, flow and pressure of liquid, gas or steam, and then convert it into 4~20 mA signal output. The working principle of LFT720B Double Flange-mounted Differential Pressure Transducer is the same as LFT710 Differential Pressure Transmitter except that the pressure transmission path on the positive pressure side is slightly different, that is the pressure acting on the high- pressure side firstly passes through the diaphragm and the filing liquid of the remote flange, and then pass to the transmitter body via capillary tube, and finally reach the high pressure side of measurement sensor.
