Product Description
Submersible Hydrostatic Liquid Level Sensor
Product Features
Good stability, high accuracy, high performance / price ratio, directly into the measured medium, installation
and use is quite convenient, solid-state structure, no moving parts, high reliability, long service life, from water, oil
to viscosity of the larger paste can be measured with high accuracy, not affected by the measured medium blistering,
deposition, electrical characteristics no material fatigue wear, insensitive to vibration, shock no polarity 4-20mA
output.
Working Principle
Measuring principle by hydrostatic pressure
When the level transmitter is put into the measured liquid at a certain depth, the pressure on the liquid surface
of the sensor is P=ρ.g.h+P0 in the formula
P: the pressure on the liquid surface of the sensor
Unit:Pa
ρ: density of the measured liquid
Unit:Kg/m³
g: local acceleration of gravity
Unit:m/s²
P0:Atmospheric pressure on the liquid surface
Unit:Pa
H: sensor into the liquid depth
Unit:m
At the same time, the atmospheric pressure P0 on the liquid surface is introduced into the back pressure
chamber of the sensor through the air guide cable to offset the P0 on the liquid surface of the sensor, so that the
pressure measured by the sensor is P=ρ.g.h. Obviously, the liquid level depth H can be obtained by measuring the
pressure P. The pressure signal sensed by the sensor is converted and amplified by the circuit and output as a
standard signal after compensation.
