Digital tachometer

The Rotaro digital handheld tachometer from RheinTech has two measuring methods; the non-contact optical method measures up to 99,999 rpm and the mechanical method, using an adapter and various probes, measures up to 19,999 rpm.

The non-contact method uses a precise beam of light together with a piece of reflective tape affixed to the rotating element to accurately measure its rotational speed. The result appears immediately on the 5-digit LCD. The distance between the RheinTacho tachometer and the test object can be up to 600 mm.

The mechanical method permits the user to connect an adapter that accepts a variety of contact probes, as well as a surface speed wheel, for precise measurement of contact RPM or surface speed and length.

The easy-to-read LCD provides various data including the measured value, selected engineering units and an indication of the selected measuring mode, whether contact or non-contact.

Example applications for the RheinTech Rotaro include motors, turbines and pumps, centrifuges, conveyors, paper, foil and textile production systems, and spool and transformer coiling machines.
