Rotation meters
Here you will find a selection of distinct  rotation meters. There are different ways of measuring revolutions within the industrial sector, either optically or mechanically. The PCE-151 handheld rotation meter with RS-232 interface can measure revolutions and velocity and store the readings onto a computer using software which comes with the device. Handheld digital rotation meters are ideal for measuring velocity and revolutions in research and maintenance. The PCE-T236 measures velocity both by contact and non-contact and has a good relation between price and quality. Non-contact measurement of velocity is done with the help of reflective tape. For a device that can be installed for measurements over a period of time, we recommend the PAX I. These devices have a digital display with digital and analogue outputs, different memory cards which are optional, and a combination of an optical sensor, a laser sensor or a mechanical measuring wheel. There is another variation for measuring revolutions and they are stroboscopes. Here you will find a description of these handheld rotation meters. If you don't find the endoscopes you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our German offices: +49 (0)29 03 976 99-52; our Italian offices: +39 0583 975 114; or our Spanish offices: +34 967 543 548 and our technical staff will advise you regarding our measuring instruments.

Here you will find various images of rotation meters in use and all non-contact devices. We also offer a wide range of digital stroboscopes that can be used as optical rotation meters.  Inside the devices there is a xenon bulb, similar to what is used in flash photography, with the difference that it emits a continuous series of flashes that can be adjusted by the user. If we have an object that is rotating at a particular rate of rpms, and we adjust the flash frequency, if the object then appears not to be turning, then the device can determine the velocity at which the object is rotating by the flash rate of the strobe. To guarantee accurate readings the device can be calibrated and an optional ISO calibration can be done in our laboratories. This calibration can be ordered with the unit or as an annual recalibration at a later date. Normally, these stroboscopes don't require recalibration annually as the bulb has a constant brightness and a long lifespan. Rotation meters are used for determining the velocity of turning parts in machines and motors without the need to make an electrical or mechanical connection.
