In various outdoor applications, wireless signals sometimes have to bridge distances of several hundred metres. This is the case, for example, with components on railway bridges. Position monitoring of the joint clearances of the bridge is taken care of by wireless magnetic sensors. If a predetermined tolerance is exceeded, the sensor will transmit a signal to a monitoring station approx. 500 m away for evaluation. In order to bridge the distance, a repeater reinforces the signal halfway. The necessary power is, in this case, supplied by a solar panel.
The switches and sensors from steute are equipped with a high IP protection class and, assuming appropriate installation, are suitable for different meteorological conditions.
