Introduction

Principle & Structure

The LV62 high temperature hydrostatic level transmitter uses a silicon piezoresistive isolation diaphragm oil-filled core as the signal measuring element. The pressure of the measured medium is transmitted to the sensor through the heat dissipation structure on the transmitter, and the signal processing circuit located in the stainless steel shell , which converts the sensor signal to a standard output signal.

Features

Wide measurement range, all stainless steel structure, various pressure interface forms, protection grade IP65;

The output signal has various forms and can be adjusted on site.

application

Non-corrosive liquid level measurement on 316L stainless steel.

Used in petroleum, chemical, metallurgy, electric power, hydrology and other industrial process sites.

Ship and aviation industry.

Hydraulic and pneumatic control system.
