Water can enter a building in many different ways and in some cases
remain undetected, causing damage and problems to sensitive
electronic equipment. Computer and mainframe rooms have a false
floor and many instances of undetected water laying in these areas has
only been detected after a problem occurred. The Water detector is an
important addition to your BLACK BOX Sensor inventory.
The Water detector is an exclusive patent pending design capable of
detecting the presence of even distilled water. The water detector
contains a microprocessor-controlled capacitance measuring circuitry.
This is far more precise than standard commercially available water
detectors, which measure the resistance of water. The resistance of
water can vary depending upon the impurities in the water. Normal
resistance type monitors are unable to detect the presence of distilled
water due to its high resistance.
The entire circuit is encased in epoxy allowing the water detector to
function while submerged in water.
The water Detector detects water leaks and flooding with a WET/DRY
indication in software. The ServSensor JR will retain any error
condition until it is read via an SNMP Get. Therefore if a water
detector encounters a critical condition at any time it will report that
condition before it returns to a normal state.
The value of the Status for the OID for switch sensors can be
“normal” , “noStatus” , “critical” or “sensorError” .
For a switch type sensor on RJ45#1 the OID for the status is.
