The HQ-2088 series high-temperature submersible level transmitter
is based on the principle that the static pressure of the measured
liquid is proportional to the liquid height. It utilizes the
piezoresistive effect of diffused silicon or ceramic sensing
elements to convert static pressure into an electrical signal.
After temperature compensation and linear correction, it is
converted into a 4~20mA DC standard current signal output. The
sensor part of the HQ-2088 series high-temperature level
transmitter can be directly immersed in the liquid, while the
transmitter part can be fixed with a flange or bracket.

Application
HQ-2088 High-Temperature Submersible Level Transmitter Features:
High-precision measurement, unaffected by foaming, sedimentation,
or electrical properties of the measured medium; wide-range
temperature compensation.
Solid-state structure, no moving parts, high reliability, long
service life; suitable for water, oil, and high-viscosity pastes.
Good stability, high accuracy, and can operate in high-temperature
environments.
Directly immersed in the measured medium, making installation and
use very convenient.
