- product specification:LFT720
- product category:Air Conditioning-Control equipment for intelligent building-Sensor
- product introduction:LFT720 Flange-mounted Transmitter is composed of LFT710Differential Pressure Transmitter and a welded liquid level flangeBetween the flange and the sensor, silicon oil and other filling fluidsare used to transmit pressure, to prevent the measured medium frompassing through the impulse pipe then impact the measurement. Theimpact of the measured medium pass through the impulse pipeincludes:crystallization, solidification, vaporization (boiling)condensation, fractionation (severe change) and etc. The Transmitteris used to measure the liquid level, flow and pressure of liquid, gas orsteam, and then convert it into 4~20mA signal output. The workingprinciple of the LFT720 Flange-mounted Transmitter is the same asLFT710 Differential Pressure Transmitter except that the pressuretransmission path on the positive pressure side is slightly differentthat is the pressure acting on the high-pressure side first passesthrough the diaphragm of the liquid level flange and the filling liquidand then pass through the transmitter body, and finally reach the highpressure side of the measuring sensor.
