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.

Note: This model is used for open container level measurement.
