2" Water Temperature Gauge (100-200°F) A temperature gauge operates by sending a low amperage current through the gauges meter to ground via a sending unit with variable resistance. The resistance of the sending units increase or decrease with the changes in pressure, temperature, etc...As the sender's resistance varies, the amount of current allowed to flow through it to ground changes and the meter deflects, showing the temperature.
Includes fire orange pointer, tall black aluminum bezel, flat glass lens, case with locator keyway to ensure proper installation and perimeter lighted black dial with stylish white graphics.
Available for MG systems, J1939 CAN Bus or J1939 Stand-Alone systems and mechanical types.
