Ge specialises in the manufacture of speedometers for 2-wheelers and a wide range of hour meters, ampere meters, pressure and temperature gauges for the oe and replacement markets. Its oe customers include reputed auto manufacturers such as lml, punjab tractors ltd, scooters india, kinetic engineering, hero motors and sooraj automobiles. The speedometers are mechanical type instruments and work on the principle of eddy current generated by a rotating permanent magnet. These are available in a wide range of gear ratios to suit most 2, 3 and 4-wheelers. Speedometer movements are manufactured in two basic types-japanese type for trucks, cars, 3-wheelers, scooters and motor-cycles and the light-duty moped type for mopeds, cycles and exercising machines. Pressure gauges [mechanical] use a bourdon tube as the sensing element and gear and-sector mechanism for pointer movement. The pressure is transmitted by tubing from the engine. Temperature gauges are bourdon tube vapour-pressure type and use a copper capillary tube to transmit vapour pressure from the sensor to the gauge. The capillary is protected from damage by a copper/steel wire braiding. Ampere meters indicate the battery charging/drain current and are moving-magnet type. Ge uses a disc magnet in ammeters which makes them very sensitive and accurate. They are available in 52 and 60 mm outer case diameters and ranges of 30, 50 and 80 amps. The company consists of sophisticated production, assembly and testing facilities for in-house production of all critical and high precision components.
