Water detector SHT 5000 12-24V

The multifunctional device of our water detectors!

Possible applications

  • Water ingress / water pipe burst
  • Pump control
  • Cistern monitoring
  • Level monitoring
  • Overflow message (e.g. drainage shaft)
  • Monitoring flat roofs
  • Combined with mini float switch also suitable for other liquids (e.g. heating oil, diesel, vegetable oil, lubricating oils, etc.)
  • Automatic bilge pumps (SHT5000-24 V for boats)
  • for water sports, hobby brewers, aquariums, model making, swimming pools, bathrooms and kitchens, workshops, etc.
  • IP 65 on request

The SHT 5000 water detector for surface-mounted fixed installation is the all-rounder among water detectors with its 4 detection lines and expansion options. Each of the 4 detection lines can be individually assigned whether the alarm is stored or the alarm transmitter is activated on contact with water, but the potential-free main relay always switches, regardless of which of the detection lines is activated. To bridge short power failures, a 9-volt block battery can be used and with the optional relay plug-in card, each detection line is additionally assigned its own small signal relay, which is interrogated e.g. by a GSM dialler or the BMS. Each individual detection line can drive up to 50 metres of LiYY cable, to which the sensors for soil moisture or mini-float switches for water levels are connected, even several in parallel.

Performance features

Water ingress in the house:
If the SHT 5000 is upgraded with the optionally available relay plug-in card, a separate relay can be controlled for each input, thus creating various combination options for controlling additional devices.

Monitoring cistern:
Level indication by 4 sensors or better and more reliable, with mini float switches: each input is indicated individually. Sensors are preferably to be used for regularly dry environment, e.g. cellar floor. Even the thinnest water films due to condensing moisture will cause the water detector to alarm or not reliably shut down, which involves a pump of dry running.
