  2. Mission Statement • To design, manufacture, market and service both standard and customized products that • detect, measure, diagnose and control SPEED under any circumstances. • To create a competitive edge for our customers’ applications, and secure high quality and reliability standards • To be dedicated to excellence and continuously develop innovative new solutions

  3. Markets served Diesel- and Gas-Motors • Cam- and Crank-Shaft speed • Turbocharger Speed • Overspeed Protection • Engine Diagnostics Industrial Applicationsi. e. Textile machines • Speed of Spinning Head • Operator Protection Automotive Applications • Speed of VG Turbocharger • Cam- and Crank-Shaft speed • Engine Diagnostics

  4. Markets served Mobile Hydraulics • Speed-Measurement • Overspeed Protection • Position Control Gas- Steam and Water-Turbines • Speed measurement • Pole wheels and Pole bands • Speed-Sensors for all Applications • Overspeed Protection Railway Systems • Brake Control • Feedback Loop for Propulsion System • Door Interlock • Black Box Information

  5. Markets served Diesel- and Gas-Motors

  6. Markets served Diesel- and Gas-Motors • Cam- and Crank-Shaft speed • Turbocharger Speed • Overspeed Protection • Engine Diagnostics

  7. Crankshaft Speed • Sensors with different technologies Electro-magnetic, Hall-effect, HF • Adapted housings and connectors • Fast and reliable signal output • Temperature range -40 .. +125 °C • GL certified

  8. Turbocharger speed Speed values of the turbocharger deliveruseful information fromthe prime mover Protection of the Turbo-charger against overspeed

  9. Turbocharger speed Sensor from rather largeto pretty small For temperatures up to240 °C With different technologiesand output signals With integral cable or connectorat the sensor body

  10. Turbocharger speed Sensor from rather largeto pretty small For temperatures up to240 °C With different technologiesand output signals With integral cable or connectorat the sensor body

  11. Overspeed protection .. and more IQ™

  12. Overspeed protection .. and more IQ™

  13. Overspeed protection .. and more Intelligent enough to be simple IQ™

  14. What is IQ™? • Overspeed protection switch • Digital to analogue converter • Signal analyse • Temperature sensor • Signal with frequency division • Sense of rotation (CW, CCW) • and, and, and .... Basically IQ™ is a Speed Sensor... ... but also a lot more than a Speed Sensor:

  15. Engine Diagnostics • Diesel engines do not run totally round. There are masses in linear movement and there are compression and burning cycles which accelerate and decelerate the system. • These effects cause variations in the speed. The speed signal contains information about the compression, the burning cycle and the internal friction; or in other words the basis for an engine diagnostics.

  16. Example of Results: Net work per cylinder Running diagram of a 6 cylinder engine over 85 total cycles having a problem on cylinder 5

  17. Possible Products using MDS 4000 Technology • Stationary Test System MDS used as test equipment at the production plant of the engine manufacturer. MDS comes as a complete unit

  18. Possible Products using MDS 4000 Technology • Test System for Service Network Special speed sensors deliver speed and diagnostic signals. This diagnostic information can be used in the service stations to gain specific information on the engine condition.

  19. Possible Products using MDS 4000 Technology

  20. Speed sensor with integrated analysis system Ready to deliver online information such as Actual torque / power value Condition of the engine Required service or maintenance Possible Products using MDS 4000 Technology
