Our ARIANA overflow protection siren is an essential accessory for every CNC machine filled with emulsion or oil. The overflow protection siren signals overflow via an audible and optical signal. The fluid level in the container can be adjusted via the modular hose. Flooding is indicated by the acoustic warning siren. The dual function can be activated by rotating the liquid level switch. Once the tank fill volume is low, the overflow protection siren is activated. To prevent the supply pump from running dry, a signal indicates that the minimum liquid level has been reached. Advantages: Acoustic control of the liquid level in your machine tool; No need to unnecessarily clean your production room and consume time; Excellent control of minimum or maximum fill levels; Easy fixation via a magnetic base; Operates on a 9V monobloc battery.
