Temperature sensor for fast moving surface
A temperature sensor device and a system for measuring temperature of a fast moving surface are described herein. A sensor body comprising a temperature sensor for measuring temperature of the moving surface. The sensor body has an engagement surface for contacting the moving surface. A biasing mechanism is coupled to the sensor body for providing pressure to maintain the engagement surface in contact with moving surface and for allowing the engagement surface to pivot with the moving surface when the moving surface deflects. An electronics module is connected to the temperature sensor for determining temperature data indicative of the temperature of the moving surface and for transmitting the temperature data to an external device. The temperature sensor device and/or the system may be used for measuring temperature of a saw blade.
