Rheintacho rotational speed sensors

These 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 applicati***, with suitable measuring systems and electronics, as well as appropriate housings, designs and connecti***. As well as this, we also provide custom soluti***, quickly and inexpensively.

Rheintacho specializes in developing and manufacturing sensors for the harshest environments. The sensors' resistance to high pressure, temperature changes, electromagnetic interference, aggressive media, water and steam jets is crucial for their operability and service life.

Rotational speed sensor applicati***:

• Ships' engines
• Communal power stati***
• Wind power plants
• Emergency power units
• Hydraulic drives (hydro motors)
• Electric drives (Material Handling)
• Road-building machinery
• Cranes
• Agricultural machinery
• Printing and paper machines
• Special machinery

Standard sensor features at a glance:

• Frequency range from true 0 Hz to 30,000 Hz
• Pressure resistance up to 500 bar as standard
• Extremely leakproof due to patented individual wire sealing
• Resistant to (hydraulic) oil, salt, alkaline soluti*** and acid
• Wide operating temperature range (-40°C to +165°C)
• Highly resistant to changes in temperature
• Highly resistant to electromagnetic interference (EMC/ESD)

Stroboscopes

Stroboscopes are versatile instruments for the visualisiation 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. For every single application the right tool for you.

Portable stroboscopes:

Stationary stroboscopes:

Stroboscope control units:

Rheintacho digital hand-tachometer

Rheintacho's tried and tested digital hand-tachometer 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 applicati***.

Rheintacho switching devices and converter

This category includes switching devices to protect against excessive or insufficient speed (ROTAS), a frequency – current/voltage transducer and a system for detecting the direction of rotation.

All these systems h***e been developed for industrial use.
The speed monitor (ROTAS) and the converter h***e GL approval.
The devices are mounted on a top-hat rail.

Electrical indicator systems

Rheintacho electrical indicator systems visualize process factors such as rotational speed, velocity, flow, filling levels and positi***. These factors are transferred as normalized voltage or current signals for display.

Rheintacho offers a range of indicators in analog or digital versi***, and in various sizes.

The indicators are exceptionally robust and ideally suited for use in harsh, industrial environments. We also take account of ergonomic aspects for the operating staff. Clear displays with a well-structured, high-contrast and clear figures enable them to read the displayed values with ease.

The many different uses of the electrical indicators are shown by applicati*** in experimental set-ups and in process monitoring, test rigs and control systems. Ideally, they are used together with our tacho generators.
The actual location of measurement can be up to several hundred ya*** from the indicator, for example on ships, where the speeds of the engines are displayed way up on the bridge.

Features at a glance:

• Clear analog or digital indicators
• Industrial standard products in various sizes
• Clear, legible display
• Sturdy design
• Long service life
• Excellent value for money
• Custom faces

Tacho generators

Rheintacho tacho generators reliably measure the rotational speeds of motors. The rotation is mechanically transferred directly via a shaft to the sender. At the output of the sender there is an electric signal proportional to the rotation. The signal is then normally transferred to a Rheintacho indicator system.

The senders are ***ailable with a normalized voltage, current or pulse output, which means that the right model can be chosen for a wide range of indicator and control units. Rheintacho also offers custom soluti*** adapted for the application.

Because of their sturdy and compact design and their electromechanical measuring procedure, the tacho generators are absolutely suitable for industrial applicati*** and are used in plant c***truction and mechanical engineering, as well as in power and drive engineering, and above all in shipbuilding.

They can measure the rotational speeds of ships' engines, turbines, rotors, rollers or conveyor belts very reliably, even under the most demanding conditi***, because this measuring method needs no external power supply. Even if the on-board supply fails completely, the tacho generator continues to provide accurate readings.

A good example of use over long distances is the measurement of the speed of a ship's engine, which is then displayed way up on the bridge.

If, for reas*** of safety, certain rotational speeds must be measured several times and with different methods, Rheintacho tacho generators are a reliable alternative to purely electronic or optical measuring systems.

Features:

• No external power supply needed
• Mechanical transfer of rotation
• Compact design
• Shock-resistant
• Powerful, normalized voltage, current or pulse output
• Tested and approved by certification institutes
• A reliable alternative to optical or electronic measuring
