This improves sensing accuracy. Solid state moisture and temperature sensors provide the sensitivity required for effective automatic control. Ice bridging occurs if incomplete melting occurs near the heater or sensor leaving an air space. The air insulates thus preventing effective heater and sensor operation. The GIT 1's unique microcontroller design frees its moisture sensor from ice bridging.
Additional features prevent heater operation under conditions favorable to heater ice tunneling.
Low voltage operation simplifies installation. Microprocessor control effectively eliminates ice bridging, eliminating the need for a separate temperature sensor. Power consumption is less than 4 watts. The heavy duty machined brass housing provides optimum protection and reliability in severe service while providing an attractive appearance. The removable top cover and plug in electronic assembly permit repair without disturbing the pavement.
