Remote level monitoring? No problem!

The alarm unit WGL 01 W consists of a control unit with integrated visual and audible alarms, Acknowledge button and a voltage-free output relay as well as a probe with a connected transmitter (3 V battery).

A jumper lets the user configure the interval at which signals are transmitted (433 MHz): every 30 seconds or every 10 minutes. The operating radius from the probe to the control unit is 150 m; however, transmission distances up to 650 m are also possible. The control unit controls and monitors all functions. Once the probe comes into contact with the liquid, the transmitter sends an alarm signal to the control unit which immediately triggers an audible alarm.

The alarm tone can be muted with the Acknowledge button. The visual alarm is automatically reset as soon as the problem has been solved or the level is correct again. The system is self-monitoring und also triggers an alarm if the transmitter has no power or if the battery needs to be replaced.

The alarm unit is supplied with AC 230 V and suitable for ambient temperatures of -30 to +60 °C. The WGL 01 W alarm unit detects all conductive liquids such as flood water, rainwater, tap water, fresh water, waste water or cooling water. The complete WGL 01 W alarm unit is fast and easy to install and commission.
