Tachometer & Stroboscope

What is a tachometer?

A tachometer is an important instrument used to measure and record the number of revolutions per minute (rpm) of a rotating machine or engine. This device provides accurate and reliable measurements of rotation, giving the operator crucial information about the machine's performance and operation. Tachometers come in various types and formats, including analog and digital variants. Most modern tachometers are digital and equipped with an easy-to-read display that shows the rpm in real-time. Some advanced models can store data and generate graphs or reports for further analysis.

Depending on whether you measure via contact with the subject, reflectors, non-contact, or with stroboscopic technique, this instrument is also referred to as a tachometer, an rpm counter, an rpm meter, or a stroboscope. 

You can use tachometers in ventilation systems, factory operations, and production, where time and precision are crucial for consistent production and quality.

Get an accurate tachometer

With a tachometer from Buhl & Bønsøe, you can measure the revolutions per time unit - also called the rotational frequency or rpm frequency. For example, you can effectively and accurately measure the rotational frequency of your machines. 

Tachometer for measuring rotations

Tachometers can be used to measure rotations, either optically or mechanically. You can achieve an accurate measurement of rpm with a laser meter, and you can also monitor your machinery and engines with a reliable tachometer. These devices are used in many different industries and applications. In industrial and production environments, they are used to monitor the rotational speed of machines and ensure operation within acceptable parameters.

Buy a professional tachometer

As already mentioned, you can measure or count revolutions by touching the measuring subject with the measuring instrument. The instrument works by emitting a laser beam from the measuring device, which is reflected in the reflectors, allowing a stable rotational speed to be measured with high precision. The smart LCD display then tells you the corresponding rpm. 

At Buhl & Bønsøe, you will find, among other things, a non-contact tachometer in the range. With it, you can measure revolutions without getting too close to moving parts at high speed.

What is a tachometer used for?

The tachometer is used to see if an engine or axle is rotating and at what speed this occurs. A tachometer can also indicate when the engine is running too fast. This is important because if the rotational frequency is too high, it can damage the engine. 

A tachometer can also indicate when the engine should have the best energy utilization. And an rpm counter can indicate when the engine should have the highest torque. A tachometer is therefore incredibly useful, both in business and in motorsport. In short - anywhere you want to optimize the performance of an engine or axle.
