What is the tachometer































Hand tachometers / tachometers
You can see handheld tachometers or tachometers on our website. With e.g. the The PCE-T236 handheld tachometer allows you to easily measure speeds and revs and transfer them to a PC using the RS-232 interface. These tachometers are also used for counting. The digital hand tachometers are particularly suitable for use in preventive maintenance and servicing of machines and systems. They enable both contact measurement and non-contact measurement of speed / rotational speed. The non-contact measurement is carried out using the reflection marks supplied. Instead of reflection marks, simple markings with a felt pen on the object to be measured are suitable in many cases. Some models of the hand tachometer have a laser target point for precise targeting of the measuring point. The PAX I speed measuring devices are ideally suited for permanent installation on machines and systems in industry / research. These devices have a digital display with digital and analog output, various optional plug-in cards are available and can be combined with optical sensors, laser sensors or mechanical measuring wheels. We also offer you a range of digital stroboscopes that can also be used as optical tachometers. If you have any questions, please use our contact form or call us at 02903 - 976 990. Our engineers and technicians will be happy to advise you on all products in the field of hand-held tachometers as well as on general questions about measurement technology.

Here you can see some pictures of the tachometers in practical use (all with an optical measurement). In order to always guarantee a high measuring accuracy, almost all tachometers can be calibrated and can be equipped with ISO test certificates (optionally available from us). Either directly with an initial order or for recalibration, e.g. annually or according to the specifications of your own in-house ISO manual. This includes a laboratory calibration and a corresponding ISO certification. The high-quality stroboscopes can also be calibrated and certified according to ISO, the only question that arises is whether it makes sense to calibrate this type of tachometer. The stroboscopes are not subject to any temporal drift and the reduction in the light intensity of the lamp (over many years) can only be viewed as minimal.
