2200 SRM 1105 Description

GeneralMeters provide information to the operator on thecondition of various systems. Gauges may be eitherdirect reading (mechanical) or indirect (electrical).Unlike mechanical gauges, electrical gauges haveelectrical meter movements, light emitting diodes(LEDs), or digital displays inside the case. These me-ters receive an electrical signal from a sender unit,usually in the engine or transmission case. This

section only describes electrical meters, senders, andinstrument panel displays.

Meters and displays are used to provide operator in-formation on the status of many systems, includingengine oil pressure, fuel level, transmission oil pres-sure, engine coolant temperature, transmission oiltemperature, and hour or fault code display. See Fig-ure 1.

DescriptionGENERAL

Many meters have meter movements that move anindicating needle attached to a shaft (or pin). Theshaft rotates to swing the needle. Shaft rotation of ameter is limited to less than one full revolution. Me-ter faces are calibrated to indicate a range of values.For examples of meter faces and indicators, see Fig-ure 1.

Many meters and displays require a separate sender.
