Robertshaw Capacitance Level Probes

The Robershaw Capacitance Level products can be used to measure the level of liquids and solids in a variety of tanks, bins, totes etc.

Robertshaw has a number of probes to use with their Control Units

The capacitance probes are normally made of SS and may be coated with PTFE for conductive liquids and sanitary applications.
