The CLS-23 capacitance level sensors are designed for limited level detection of electrically conductive and non-conductive fluids in vessels, reservoirs, sumps, pipes, tanks, etc. The sensitivity of the sensor can be easily set by placing the magnetic pen on the spot. The process coupling at the housing can be with a metric thread (M18x1.5 ; M20x1.5), pipe thread (G3/8″ ; G1/2″) or sealing thread(NPT 1/2–14). Output performances – transistor output with open collector (PNP), two wire electronic switch (S) and NAMUR output.
