Level SwitchThe Model FCLS Flush Capacitance Level Switch from the Proximity Division of Dwyer Instruments, Inc., is a good fit for level measurement of liquids and bulk solids to trigger an alarm or close a filler inlet. No-probe design allows for installation where space is constrained or where material flow or material build-up would damage a probe. With no moving parts, this level switch assures no jams, no wear, nothing to break, and no maintenance. The level switch comes standard with IP65 housing with a maximum pressure limit of 185 PSI (19.7 bar).
