High-temperature Submersible Level Transmitter
- Product Description
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.
HQ-2088 High-Temperature Submersible Level Transmitter Overview:

The sensor portion of the HQ-2088 series high-temperature level transmitter can be directly immersed in the liquid, while the transmitter portion can be fixed using a flange or bracket.
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.
