Hydrostatic Type Level Transmitter

Product Overview

Liquid level transmitter adopts refined encapsulation technology and perfect assembly process to ensure the product

long-term work without leakage and high stability. Front sand cap plays a role in protecting the sensor membrane,

waterproof air-conducting cable is connected with the shell sealing, the vent tube adopts polymer isolation plug and

connected with the outside, at the same time, it is also equipped with an amplifier circuit inside which can directly transmit

stable amplified signals, and according to the principle that the pressure generated by different specific gravity liquids at

different heights becomes a linear relationship, it realizes the accurate measurement and transmission of the volume, height

and weight of the water, oil and pasty materials, which is applied to water conservancy, environmental protection, industrial

process control, petroleum, chemical, pharmaceutical, new energy and other fields of liquid level measurement and control.
