DCS Continuous Capacitive Sensor

Product Description

The Deeter Capacitive Sensor (DCS) is a reliable alternative to our range of float switches, specifically designed for use in cryogenic applications and other non-conductive liquids. With no moving parts, accurate level measurement takes place within the custom length hollow probe. The open ended probe allows liquid to flow in and out from the bottom of the sensor where turbulence is at a minimum, making it ideal for use in fast flowing or turbulent applications.
