Submersible Pressure Level Sensor

Submersible pressure transmitters or sensors use piezoresistive technology. These sensors are oil filled, stainless steel integrated structure with IP68 grade, suitable for liquid level and depth measurement. The stainless steel, hermetically sealed housing makes them suitable for immersion in almost all kinds of industrial liquids and oils. They are designed to give accurate readings at pressure ranges from 50 mbar up to 20 bar (corresponding to water column depths of 0.5 m to 200 m).

Category:

The electrical connection of submersible level transmitter is a specially designed PE cable with air vent tube and the pressure connection part is an exposed 316L stainless steel corrugated diaphragm, hence no blocking problems due to no pressure port and easy for daily maintenance. The all-welded design eliminates the need for an O-Ring seal, thereby eliminating potential leak paths. These sensors are designed with amplified signals, typical 4-20mA output or 0-10V, 0-5V voltage output.
