Product Details
ATEX Explosion Proof 4-20mA Water Level Sensor
WNK immersion water level sensor transducer is suitable for liquid
level, pressure or depth measurement. With high accuracy and high
stability diffused silicon internal sensor, WNK level sensor offers
good long-term level monitoring. Made of stainless steel housing
and SS316L diaphragm, WNK sensor can be used in most industrial
liquids and oils.We have two types of input cable: Polyvinyl Fluoride and PTFE, which are suitable for non-corrosive
and corrosive medium measurement.
Each level sensor housing is tested in-house via a helium leak
tester to ensure proper protection. Ventilation tube in the cable
automatically compensates for changes in atmospheric pressure above
the tank.
Our submersible fuel / water level sensor can be used to measure
water level, fuel level and other liquid level; well depth;
groundwater level; bore well, underground water, river etc,.
