Alarm unit ÖWU

Combination probe for determination of leaking medium oil and water For storage rooms, manholes, drip pans and pumps With fail-safe mode With visual/audible alarms, Test/Acknowledge buttons and relay output Application For visual and audible alarms if liquids with a flash point of > 55 °C are detected. Suitable for the following media: water, fuel oil, diesel fuel or low-viscosity lubricating oils, motor oils, gearbox oils or hydraulic oils, vegetable oils and transformer oils. Separate detection of electrically conductive and non-conductive liquids. Description Alarm unit in wall mounting housing for early detection of accumulations of liquids. ÖWU consists of a control unit with visual/audible alarm, Test and Acknowledge buttons, two relay outputs as well as a combination probe with photoelectric and conductivity sensors. An integrated microprocessor determines whether the detected medium is oil or water. The probe is mounted at the lowest point of the object to be monitored. Alarm is triggered when there is contact with escaped liquid. The audible alarm can be muted with the Acknowledge button. The visual alarm is cleared once the leak has been removed. The Test button allows you to simulate an alarm condition in order to perform a function test. The two voltage-free relay contacts are provided for connection of additional external alarm equipment or additional alarm units; e.g. 1 relay for water alarm and 1 relay for oil alarm. ÖWU features a "fail-safe" mode. The alarm units are suitable for panel mounting with a mounting frame. A sealing kit (IP 54) is available for rough application conditions.
