What advantages does the LWS have as compared with the 237?
The ability of the LWS to detect water on its surface is not limited by the size of the water droplets, as it can be with a 237.
The LWS is ready to install for most applications, whereas the 237 requires further preparation before installation.
The LWS can detect the presence of ice and differentiate ice from water. In contrast, when ice forms on the 237, the sensor’s output is no different from that of a dry sensor.
