Available products in different pressure and cable length

Features

Descriptions
SS634 series submersible pressure sensors use piezoresistive technology, oil filled, IP68 grade, suitable for liquid level and depth measurement. Their hermetically sealed housing makes them suitable for immersion in almost all kinds of industrial liquids and oils, are designed to give accurate readings at pressure ranges from 100 mBar up to 20 Bar(corresponding to water column depths of 1 m to 200 m).

The electrical connection is a special designed PU cable with air tube and the pressure connection part is an exposed 316L stainless steel corrugated diaphragm, easy for daily maintenance. Typical applications including water and sewage treatment plants, water level monitoring at reservoirs, dams, down-hole water wells.

Installation and precautions
*** The installation place should be easy to operation and fixing
*** When installation, the metal probe should sink to the bottom of the container
*** The installation place should be away from the heat source as far as possible
*** If the customer need to connect with other cable, waterproofing measures must be taken
*** When the sensor put into the water, it is the best that the sensor can be fixed, and away from the inlet

Precautions for safety use
*** Clean the metal probe(sensor) regularly to avoid block the pressure port
*** The cable is a special waterproof cable, abrasion, puncture, and cut the cable is not allowed
*** The wiring should strict reference to the electrical connection, wrong wiring will cause damage to the sensor
*** A stainless steel 316L diaphragm is in the front part of the sensor, artificially foreign body touch is not allowed
