Car Gauges

Car Gauges

The terms “gauge” are usually used to denote the receiver and transducer of the measured physical quantity.

Gauge construction

The gauge consists of at least a sensing element that senses changes in the measured physical quantity and an element that converts the non-electric signal of the sensing element into an electric one.

Types of car gauges

By purpose, the gauges of modern cars can be divided into four groups: gauges of control devices, gauges of emergency conditions, gauges of ignition systems and gauges of electronic engine control systems.

Gauges of control devices are elements of an information-measuring system that provides the driver with information about driving conditions, operability, or about the condition of units and the car as a whole.

The gauge together with the pointer (receiver) and the elements of electrical communication between them make up a control measuring device.

The gauge is installed at the measurement site and converts the measured physical quantity into a proportional electrical signal. At the receiver, this signal undergoes an inverse transformation.

Depending on the purpose of the control device, various types of gauges are used: temperature, pressure, fuel level and vehicle speed (speedometer sensor). The types of sensors of domestic cars are given in table. 1.1.
