LPD-310A Series

Digital display input level gauge

LPD-310A digital display input liquid level meter is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid. After the circuit processing and output, through temperature compensation and linear correction, it is converted into standard 4-20mA or other different standard electrical signals to measure the liquid position. It has the advantages of wide measuring range, field programming display, diversified information output, built-in temperature compensation, and slight corrosion resistance, which can meet most measurement needs.

Specification

Performance Features

Performance characteristics:
LPD-310A digital display input liquid level meter is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid, using foreign advanced isolated diffused silicon sensor or ceramic capacitive pressure sensor, the static pressure is converted into electrical signals, and then through temperature compensation and linear correction, converted into standard electrical signals (generally 4 ~ 20mA/1 ~ 5VDC). Is a widely used in mechanical engineering, automatic control of the level meter, can be connected to the meter head, recorder, computer, PLC program controller or alarm.

Application field:
