Most motorists and car enthusiasts will be familiar with tachometers as they are usually the most prominent instrument displayed on car dashboards. A tachometer, also known as a rev (revolution) counter, tachymeter, tach, or speedometer is an instrument measuring the rotation speed of a shaft or disk within a machine. Values are typically reported on both analogue and digital displays in revs (revolutions) per minute, which is often shortened to RPM in most scenarios.
There are many different types and constructions of tachometer, each have their relevant advantages and disadvantages suited to specific applications across a wide variety of sectors. The most common types of tachometers are electronic or mechanical, with some being attached to the actual item they are designed to measure (contact) and others taking measurements with the use of infrared light and therefore not requiring direct contact with the application (non-contact).
Despite the significance of tachometers in the automotive industry, they are also used in many other industries and applications such as:
As with all test instruments tachometer measurements can drift over time so regular tachometer calibration is an essential part of any planned preventative maintenance. Calibrationhouse boasts onsite and laboratory-based tachometer calibration services, both performed with many years of knowhow and highly accurate tachometer calibration standards.
