LFT720A Flange-mounted Differential Pressure Transmitter is composed of LFT710 Differential Pressure Transmitter and a welded liquid level flange. 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 then 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 4~20mA signal output. The working principle of the LFT720A 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 first passes through the diaphragm of the liquid level flange and the filing liquid. and then pass through the transmitter body, and finally reach the high pressure side of the measuring sensor.
