Greisinger 600658 GEWAS 300 SP Water leak detector no sensor mains-powered

The measurement methods for fill level detection are based on the conductive principle, in other words, the electrical conductivity of the medium is monitored. If the switching amplifier determines a value smaller than the preset conductivity, then the state "media detected" is returned, otherwise "no medium".
Application: versatile alarm and protective device for DIN rail, or wall-mounting with universal input (screw) for a variety of external sensors. It allows all sensors with a switching threshold of< 100 kOhm to be connected, such as water sensors, float switches, level switches, magnetic contacts etc. In case of alarm, a potential-free changeover contact a connected device (for example, pump, machine) to be switched on or off. The GEWAS 300 SP will also sound an acoustic alarm. To clear the alarm, the internal/external reset button must be pressed. The GEWAS 300 FG is suitable for detecting conductive media (water etc.) It is less suitable for weak or non-conductive media (oils or fatty liquids), conductive foam-forming media or media that allow electrically insulating deposits to form on the electrodes.
