Model OAA-100.A1 -Liquid Level Alarm Indicator

Our alarm indicators type OAA-100.A1 are stand-alone signaling devices with optic and acoustic alarm indication. Combined with a liquid level sensor (e.g. T-200.F...) and a leak detector (e.g. T-200.L...) the OAA-100.A1 can be used as a local monitoring device of a tank. OAA-100.A1 records the limit-value signals of the connected level sensor / leak detector and releases an acoustic signal (acceptable) and an optical signal (not acceptable).
