Overview
Description
Rain sensor with heater and professional, functionally reliable measuring principle (12V)
The large sensor surface reacts to rain or snow. The switching polarity and sensitivity are adjustable. The switchable heating prevents icing or condensation and accelerates drying. In the most sensitive setting, the device is also suitable for detecting fog.
The mast or wall mounting bracket, available as an accessory, enables easy installation. Typical areas of application are in garden centres, in agriculture, in building control systems, but also in the home and garden.
The rain sensor works on the basis of an alternating current measuring system (electrolytic measuring principle). The advantage is that no sensor electrode can degrade and therefore has a significantly higher life expectancy compared to other sensors with direct current measuring principle (as almost 80% of all devices on the market).
The potential-free relay contact closes when rain starts. The relay contact can transmit any voltage, e.g. 12V or 24V, to the evaluation electronics, e.g. an ESERA 1-Wire Digital Input or 1-Wire Switch Input Module.
