Pressure transmitter 4 meters wg with 5m cable

Submersible transmitters for water level measurements

This submersible water level transmitter is notable for its excellent long term stability, rugged build and a low cost, value engineered design. The KAVLICO low pressure capsule measures the pressure generated by the head of water above it very accurately, and is enclosed in a sealed brass housing with a clamped cable entry at the rear. A clamp ring terminates the cable screen to the brass housing and the signal wires are moulded into the body, acting as a secondary hydraulic seal. This brass housing is mounted in a second waterproof plastic housing. The measuring cell and the cable are sealed with secondary O-rings. The pressure media is therefore only in contact with the plastic housing - which can be selected to suit special applications - and the goldplated ceramic diaphragm. The cable is also double sealed. The first sheath seals the conductor wires and the reference tube, which are then mechanically protected by a heavy-duty braid and covered by a thick polyurethane sheath.
Level transmitters can be subject to internal condensation caused by installations in cold water on warm, humid days. If the reference tube is not terminated in a warm, dry enclosure, KELLER recommends the use of a purpose built cartridge filled with a silica gel which is fitted at the end of the reference tube.
