תיאור
Capacitive proximity switch CPS–24 is intended for detection of proximity or motion of solid objects. It is suitable for indication of
the liquid level through non-conductive walls of vessels or on non-conductive gauge-pipes. It is excellent for liquid leakage detection
in collection pits or directly on floors. The sensor state is indicated by LED. The sensitivity is adjustable by a trimmer located under
a cover screw on the rear side. The design and housing materials of CPS allow the use in complicated environments (harsh, dusty,
explosive, aggressive) as well as in clean environments (medical technology).
