Liquid detector 24V 40894

Warning device for visual and audible alarms in case of accumulations of liquid occuring e.g. caused by leaks, backwater or floodings. The device is suitable for the media fuel oil, diesel fuel, low-viscosity lubricating oils, motor oils, gearbox or hydraulic oils, vegetable and transformer oils, water and other liquids. The set consists of a signal unit with visual and audible alarm, test/acknowledge button, relay output and photoelectric probe. The probe is mounted at the deepest place in the area to be monitored. In case of an alarm, a visual and audible alarm is triggered and can be ended by pressing the acknowledge button. The visual alarm remains until the leakage has been removed. The test button allows for functional control by simulating the alarm case. Additional external transducers or a building service can be connected via the potential-free relay contact.

Optionally, a 9V battery can be connected so that in case of power failure an alarm sound is triggered. The alarm cannot be acknowledged and ends as soon as the power is back on.
