Signal WEL-FW-B Frostwatch Temperature Sensor with Included Power Supply

The Signal WEL-FW-B FrostWatch Temperature Sensor is a reliable, plug-in frost detection unit designed to safeguard sensitive crops, turf, or irrigation systems from temperature-related damage. Fully compatible with Signal SDS Series Two-Wire Irrigation Controllers, this sensor activates pre-programmed frost response actions—such as pausing irrigation programs or triggering protective watering cycles—when freezing conditions are detected.

Supplied with its own plug-in power supply, the WEL-FW-B is simple to install and can be positioned in a frost-prone area of the site for accurate ambient temperature sensing. It connects to the controller via a DataNode Switch Input, allowing real-time communication of frost events back to the SDS controller interface or SignalCloud™ software.

Built for long-term outdoor use, this sensor is ideal for agricultural operations, turf facilities, and commercial irrigation networks where frost damage can result in costly setbacks.
