A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. [1] The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
The most common wheel speed sensor system consists of a ferromagnetic toothed reluctor ring and a sensor (which can be passive or active).. The tone wheel is typically made of steel and may be an open-air design, or sealed (as in the case of unitized bearing assemblies).
The mini-DIN connectors are a family of multi-pin electrical connectors used in a variety of applications. Mini-DIN 9.5 millimetres ( 3 ⁄ 8 in) is similar to the larger, older 13.2 mm diameter DIN connector .
An auto tachometer has a sweep of about 240-250 degrees and typically uses an air core gauge. An air core gauge is a specific type of rotary actuator in an analog display gauge that allows an indicator to rotate a full 360 degrees. It is used in gauges and displays, most commonly automotive instrument clusters.
The tach timer integrates over time the instantaneous rotation speed displayed by the tachometer. The displayed number is incremented by one if the engine is run at its reference speed for one hour. The displayed number is incremented by one if the engine is run at its reference speed for one hour.
Earlier tachograph heads displayed the mode as a thin line in one of four concentric tracks within the activity band. These heads are known as manual heads as the activity was manually selected using the mode switch. Automatic heads succeeded manual heads, and differ from them in two main areas. Firstly, the automatic head will always display ...
The Mini-A connector and the Mini-AB receptacle connector have been deprecated since May 2007. [13] Mini-B connectors are still supported, but are not On-The-Go-compliant; [14] the Mini-B USB connector was standard for transferring data to and from the early smartphones and PDAs. Both Mini-A and Mini-B plugs are approximately 3 by 7 mm (0.12 by ...
Tachymeter scale on a Citizen watch bezel. A tachymeter (pronounced / t æ ˈ k ɪ m ə t ər /) is a scale sometimes inscribed around the rim of an analog watch with a chronograph.It can be used to conveniently compute the frequency in inverse-hours of an event of a known second-defined period, such as speed (distance over hours) based on travel time (distance over speed), or measure distance ...
