1. Product Brief Introduction:
The HQ-2088 series high-temperature input liquid level transmitter
is based on the principle that the measured liquid static pressure
is proportional to the height of the liquid. It uses the
piezoresistive effect of diffused silicon or ceramic sensitive
elements to convert static pressure into electrical signals. After
temperature compensation and linear correction. Convert to 4-20mADC
standard current signal output.
The sensor part of the HQ-2088 series high-temperature liquid level
transmitter can be directly inserted into the liquid, and the
transmitter part can be fixed with a flange or bracket.
The input head of this type of liquid level transmitter does not
need to be equipped with a protective cap, and the measuring
membrane comes into contact with the medium over a large area. The
sensor used is a ceramic capacitor membrane, which has strong
impact resistance, is not easy to block, and is easy to clean,
further leveraging the excellent corrosion resistance of ceramic
sensors. Industrial High Temperature Level Sensor Rs485 Water Level
Indicator for tank with Alarm Seawater Level Sensor.
2. Product Features:
High precision measurement, wide range temperature compensation
unaffected by foaming, deposition, and electrical characteristics
of the measured medium;
Solid state structure, no moving parts, high reliability, long
service life, can be processed from water, oil to viscous paste;
Good stability, high precision, and can work in high temperature
environments;
Directly put into the tested medium, installation and use are quite
convenient.
