rOduCT dESCriPTiON Through wall level switches GPLS-25 are intended for liquid (conductive and non- conductive) level detection on glass or plastic gauge-pipes, tubes and tanks. The sensor is equipped with high frequency technology,which allows reliable operation even for sensing of the adherent electrically conductive medium. The sensitivity and modes (O - normally open or C - normally closed) of the switches can be easily set by placing magnetic pen on sensitive spot.
imENSiON drawiNgS Variant"A" with cable outlet Sensitive spot for setting cable Electrode Variant "C" with connector GPLS–25N–0 GPLS–25N–1 Magnetic pen MP–8 ECOmmENdEd raNgE OF aPPliCaTiON Detection of various types of liquids - water, disel, oil, cooling liquids, water solutions, some types of solvents. It is suitable for glass or plastic gauge-pipes, vessels, plastic container tanks, plastic tubs, pools, canisters, etc.
NSuiTablE raNgE OF aPPliCaTiON The sensor also is not intended for level measurement on the gauge-pipe and the container wall with antistatic treatment (partially electrically conductive). rOCEdurE FOr PuT SENSOr iNTO OPEraTiON 1. i NSTallaTiON a) The sensor type GPLS–25N–0, which is intended to point level detection on plastic or glass and gauge-tubes.
2. E lECTriCal CONNECTiON a) The type of sensor GPLS–25N–_-S Positive pole (+U) of power supply is connected through a load (relay) to brown wire or pin connector No. 1, negative pole is connected to while wire or pin connector No.3. Connection scheme of sensor with “S“...
3. S ENSOr SETTiNgS The setting is done by placing of magnetic pen MP-8 to sensitive spot located on the front of the sensor. Short time attaching (up to 2 sec.) of the magnetic pen to the sensitive spot makes the sensor open.
b) Mode C (normally closed) Put the level of the measured medium in the state below the lower edge of the sensor in the tank or in the gauge-pipe. Attach the magnetic pen MP-8 to the sensitive spot for minimum 4 seconds. When the LED lights up, the sensor is in the state closed.
