The PR3420 submersible depth and level transmitter has been designed for the accurate measurement depth in sludge/slurry materials.

The transmitter is mounted on a sludge platform to lift the sensing diaphragm above the sludge/tar level. This prevents build-up of foreign matter on the sensor face, which could affect performance of the transmitter.


Level or contents measurement of liquids where sedimentary deposits may occur in storage tanks, rivers, seabed, etc.
