LPD-310A Series
Digital Submersible Level Transmitter

The LPD-310A digital display input liquid level gauge is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses foreign advanced isolated diffused silicon sensitive elements or ceramic capacitive pressure sensitive sensors to convert the static pressure into electrical signals, and then through temperature Level compensation and linear correction are converted into standard electrical signals (generally 4~20mA/1~5VDC). It is a liquid level meter widely used in mechanical engineering and automated control. It can be connected to meters, recorders, computers, PLC program controllers or alarms, etc.
