Wireless filling alarm for closed tank with with s

Wireless fill level alarm for monitoring the liquid level in sludge tanks.

The Tank-Check RF-412 wireless fill level alarm is easy to install. The location of the display unit inside the house is freely selectable, and installation requires no special expertise or digging of cables. The fill alarm works wirelessly, with a range of up to 100 meters. Both sound and light alerts notify when the liquid level rises above the selected threshold. The alarm also has a relay output for transferring the alarm signal to a GSM modem, for example.

The sensor cable can be extended up to 20 meters. The sensor cable is attached to the electronics board with screws, making it simple to extend. Smartel recommends a 2 x 0.5 LIYY cable.

The resistive sensor detects the liquid level in the tank or drainage well.
The outdoor unit’s electronics are fully moisture-protected.
Designed to withstand Nordic weather conditions.
Sound and light alarms are triggered if the radio link fails, for example, due to a dead battery.
