Product description
Flood detector/sensor with built-in amplifier. Voltage-free relay contact. Alternative to Cavia water nuisance detection. Fully in IP67 design. The robust water detector GBS is suitable for almost all situations where water needs to be detected: under a computer floor, in an archive basement, swimming pool, technical room, tunnel, pump station, elevator shaft and other demanding environments. This water detector can be connected directly to a BMS (Building Management System) or an alarm system. Universal Guinea pig alternative for water detection, operates on 12 or 24 volts, both AC and DC voltage.
Applications
Water detector BMS with memory function
After a leakage, both LEDs will flash. Performing a reset (memory empty) is done by briefly interrupting the power supply. The water detector GBS can be used for water + all other electrically conductive liquids, such as milk, fruit juice, alcohol, acids, chemicals.
Robust and maintenance-free
The floor sensor is encased in a waterproof IP67 housing with 4 stainless steel detectors at the bottom. The entire water detector is flood resistant (permanent immersion). One LED indicates power supply and the other serves as an alarm indicator. The Water Detector-GBS is maintenance-free. It is sufficient to remove any dust once a year and check the operation using a wet cloth or sponge.
Protected against wire breakage
In idle state (with power connected) the green LED is lit and the relay contact is engaged. When the sensor detects water, the red LED illuminates, the relay contact drops and the alarm contact closes. This protects the water detection system from wire breakage and power loss. You can connect the potential-free alarm contact directly to a BMS, as well as to an alarm or intrusion system or GSM detector.
Floor-mounted water detector
This compact water detector is a great alternative to the guinea pig water nuisance detector. Advantage: this water detector does not need amplifier(s) or additional modules. It operates standalone on safe low voltage. Professional/ industrial quality. The sensor housing contains no screw holes: for fastening, a special mounting bracket is available as an option. The housing has a molded-in connection cable (flexible and strong), which may be extended or shortened if necessary.
