Rheintacho Messtechnik GmbH

Company information:

Rheintacho Messtechnik GmbH is a company with a long tradition. Since 1901, we have been developing special solutions using rotational speed measurement technology for mechanical processes. More than 70 members of staff are employed at our headquarters in Freiburg.

Our UK-subsidary, Foundrometers Instrumentation, located close to Leeds, is taking care for sales and marketing activities within UK and manufacturing of mechanical tachometer and other special solutions.

Our own development, production and assembly departments guarantee fast and innovative solutions that meet individual customer needs. Our product portfolio covers a broad range of high quality technical solutions for rotational speed applications such as speed sensors, rotational speed indicators, switching devices and converters. Hand held measuring devices such as hand-held digital tachometers and stroboscopes comprise another large part of our product range.

Speed Sensors
Rheintacho sensors are designed to withstand the harshest conditions and record the rotation of machine parts without contact. They can withstand high pressures, are waterproof, can be used within a wide temperature range and are resistant to oil, salt and acid. Our scope of supply contains speed sensors with different measuring principles for nearly every application. Main products in that range are speed sensors for the combined detection of the rotational speed and direction.

Digital hand-tachometer
Rheintacho's prooven and tested digital hand-tachometers record rotational speeds and run lengths. Some of them use a proximity system by shining a light beam on a reflective mark; others use a contact system with special adapters for different applications.

Stroboscopes are versatile instruments for the visualisation of very fast movements. They are important and necessary tools for the inspection and control of machines and manufacturing lines eg 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. Rheintacho offers stroboscopes in different design and technologies (stationary or portable models – LED light or XENON light), for every single application the right tool for you.

Switching devices and converter
The programmable ROTAS rotational speed monitor measures the motion of engines, machines and systems. Thanks to its wide variety of functions and its variable programming options, it can be flexibly adapted to many different system requirements.

The F/U F/I converter converts frequencies in to currents or voltages with accuracy and long-term stability. One of the many uses of this converter is recording system factors such as rotational speed as part of preventive servicing.

If no 24 V DC power supply is available for the sensors, Rheintacho can offer a power pack suitable for industrial use.

Tacho generators
Our tacho generators produce a current or voltage signal in proportion to the measured rotational speed. This signal can be transferred over long distances so that the rotational speed can be displayed at a remote location or used for control applications.

Electrical indicators
Rheintacho electrical indicators are sturdy and reliable. They can display frequency, voltage or current and are used together with Rheintacho tacho generators or other sensors. We create custom faces for the application.

Mechanical indicators
Rheintacho mechanical rotational speed indicators need no electricity at all. They are connected directly in position via a shaft. They have a long service life and are also very sturdy and reliable.
