CPS-24 CAPACITIVE PROXIMITY SWITCH


  • Detect liquids in glass or plastic pipes, indicate liquids in inter-coat space of double coated tanks
  • Adjustable sensitivity
  • NPN, PNP or NAMUR output
  • Material of housing and nut from stainless steel
  • Version for usage in explosive areas
  • LED state indication

 

Capacitive proximity switch CPS–24 is intended for detection of proximity or motion of solid objects. It is suitable for indicationof 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 fl oors. 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).

Description

ELECTRICAL CONNECTION

Sensor with NPN or PNP output is allowed to lead only by resistive or inductive lead. Positive supply voltage (+U) is connected to the brown conductor BN (1), negative (0 V) to the blue conductor BU (3) and the leads (only NPN or PNP type of output) to the black conductor BK (4). The capacity loads and low resistance loads (bulb) is evaluated by the sensor as short circuit.
Note: In case of strong ambient electromagnetic interference, paralleling of conductors with power distribution, or for the distribution to distance over 30 m, we recommend to use shielded cable.

 

SENSOR SETTING

The sensitivity is set by trimmer located under cover screw on the rear side. Clockwise turning makes the sensitivity lower, reverse direction turning makes the sensitivity higher. The sensor is factory adjusted to basic sensitivity. Real sensitivity (sensing distance) depends on sensing material.

 

AREAS OF APPLICATION

Detect liquids in glass or plastic pipes, indicate liquids in inter-coat space of double coated tanks. Detection of various kinds of non-abrasive bulk-solid materials (granulates, cereals, sand) in non-conductive containers. Sensing of moving objects.
