LEAKSENSE LKA-24/230V Leak Alarm


• Multi-voltage: Supply voltage 24V AC/DC or 230V AC
• Selectable reset: auto/manual
• Alarm repeated after 24 h when manually reset
• 2 alarm relays (energized in no-alarm condition)

Our LEAKSENSE LKA-24/230V is designed for monitoring of electrically conductive fluid leakage, such as water. Application example: computer centres, archives, lofts, floor/ceiling structures.
LEAKSENSE LKA-24/230V is fitted to a DIN rail and adapted to ingress protection standards. The sensor tape is installed at the lowest point at the monitoring site.

LEAKSENSE LKA-24/230V measures the resistance in a sensor tape which consists of 2 conductors weaved into a textile strip with an end resistance of 680 kOhm at the farthest end. The resistance changes when water comes into contact with the textile strip and the LEAKSENSE LKA-24/230V activates an alarm. The relays activate alarms and the green LED flashes at 1 Hz when there is an interruption or short circuit in the sensor tape.
The sensor tape can be up to 100 meters long.
