Provided range of Electrical Gauges is used as integral parts of tractors, truck and other automobiles. These are required to denote fuel level of vehicle oil tank. Brass forged housing ( 42 mm to 60 mm diameter range) of these instruments is highly durable. Operating principle of these products depends on NS moving magnet technology. With having 12v to 24v voltage range, these adopt eccentric movement based sweep angle. Based on their design, these Electrical Gauges consist of solid brass bolts, BA 9512/24V bulb, return or ferrite magnet. Sensing unit of these measurement instruments is used to detect leakage in oil tank.
