SENVA WD-1 Water Detector
Specifications
-
Power Supply Output: 12-24VDC/24VAC +/- 15%, 5W Max. Isolated N.C. (Form B) Solid State Relay, Isolated Output
Rating: 30VAC/DC, 0.1A (100mA) Max. -
Sensing: Gold-plated electrodes
-
Operating Environment: -20 to 70°C / 0-95% RH non-condensing
-
(1) Isolated Power supply from earth ground required.
Product Installation Instructions
- Install a sensor in the area to be monitored such that probe pins will contact collected water.
- Fasten the sensor with screws provided, or other means.
- Wire sensor as follows:
- RED = Power Supply 9-30VAC/DC
- BLACK = Ground/Common
- WHITE = N.C. (Form B) Switch
- GREEN = N.C. (Form B) Switch
Operation
Switch output opens when sensing probe pins are bridged by water, or power
is removed. The device is also equipped with a status LED:
- Green : Normal operation, no water detected
- Red: Alarm Status, water detected
The water supply must be less than 1,000k (1M) ohms. Nearly all water supplies contain sufficient dissolved minerals to trigger the sensor including Filtered, Tap, Rain, Condensate, Melted Ice, Detergent, and Salt. Not suitable for detecting distilled water.
Dimensions
Sensing probes utilize alternating current sensing (even when powered by DC)
to prevent electrolysis and oxidation of the sensing probes.
