Rotational speed sensors use various magnetic proximity measuring principles to monitor the speeds of machine components in a range between 0 and 30,000 rpm. The application itself determines the measuring principle used. RHEINTACHO offers a wide range of standard products for the most varied applications, with suitable measuring systems and electronics, as well as appropriate housings, designs and connections. Additionally to this, we also provide custom solutions, quickly and inexpensively.

Stroboscopes are versatile instruments for the visualization of very fast movements. They are important and necessary tools for the inspection and control of machines and manufacturing lines e.g. in printing or textile industries. Stroboscopes could also be used for the non-contact measuring of rotational speed. If the stroboscope flash frequency matches the frequency of movement, the test object appears stationary. It can be observed and its frequency of movement recorded. The range of products available today allows bandwidths exceeding three metres to be illuminated.

RHEINTACHO’s tried and tested digital hand-tachometer record rotational speeds and run lengths.

The digital hand-tachometers are just as useful when setting up plants and machinery as during service jobs, monitoring manufacturing processes or in development laboratories. Example applications include measuring the rotational speeds of engines, pumps and turbines, as well as of mixers, centrifuges and conveyors; it can also measure the velocities and lengths of all kinds of sheets and belts.
