Level sensors (flood sensors) consist of metal sensing electrodes and a plastic head containing evaluation electronics. The connection of 24 VDC or 24 VAC supply voltage as well as the resting state of the relay or transistor output are indicated by a green LED. The failure state (forming of a conductive connection between the electrodes) is indicated by a red LED inside the box and a change of the state of the output transistor or relay contact. The selection of the relay output is done through the placement of a jumper on the PCB. All metal parts are made of stainless steel DIN 1.430, the basic length of the sensing electrodes is 50 mm. The supply cables are connected to the terminal board through bushings, which are part of the plastic head. The basic material of the head is POLYAMIDE.

Level sensors (flood sensors) operates on the principle of different conductivity of air and water. Water becomes conductive to a certain extent due to dissolved mineral and organic substances. Under normal conditions (rain water), it has a conductivity of 5 mS/m and higher. This value reflects also on the setting of the sensitivity of the sensor with a margin (less than 1 mS/m). Once the electrodes are connected by a conductive medium, current starts to flow through the circuit (of the order of μA), which is then detected by evaluation electronics. This leads to state indication by a red LED, activation of the output transistor (open collector) or closing/opening of relay contacts.

Level sensors (flood sensors) indicate fault conditions associated with water leakage in industrial plants as well as in rooms, offices or production halls within the range of 0 to 80 °C. The level sensors (flood sensors) meet the ingress protection of IP 65 according to EN 60 529, as amended and satisfy the conditions for operation in a normal, non-aggressive environment. The method of use must be chosen with regard to the temperature resistance of the sensor head and chemical resistance of the sensor housing and head.

Possible applications:

  • pump shutdown upon reaching a required level
  • flooding of buildings by groundwater, floods, sewage
  • flooding of sumps, pump activation upon reaching a certain level
  • indication of water leakage from a washing machine, boiler, pump unit, etc.
  • flooding of a room in the event of various equipment failures – broken toilet water supply line, overflowed bathtub, sink
  • monitoring of condensate in a ventilation duct

DECLARATION, CERTIFICATION, CALIBRATION

  • Manufacturer provides EU Declaration of Conformity
