■ Measuring on turbo vanes and shafts ■ TTL output for speed measurement ■ Analogue monitor output for gap control ■ High resolution ■ High dynamics ■ Low current consumption ■ High noise immunity

The SM series offers ultimate reliability and precision in a small size, and is designed for industrial and lab use. With a measuring range from 2 up to 200 mm and various configuration options (mechanics, protection class, temperature range, linearity) the SM series ensures to have a suitable measuring system for every application. ■ High precision and linearity ■ Various configuration options ■ Push-rod guided and unguided, spring loaded ■ Stainless steel housing ■ Linearity up to 0,10 % ■ Measuring range 2...200 mm

With an extended measuring range up to 45mm, the new eddy current sensor series completes the product portfolio of eddylab GmbH and at the same time combines all advantages of a non-contact eddy current measuring principle: With wear-free distance and displacement measurement, eddy current sensors are characterized by highest precision and dynamics. The new T14/T20/T40 series can withstand extreme temperatures in a range of -40...+150 °C without any problems and is insensitive to external influences such as dirt and dust. The new sensors with measuring ranges between 14 mm and 45 mm are also extremely compact and robust. This makes them ideal for use in difficult industrial environments or vibration measurements with larger amplitudes. Together with the TX electronics from eddylab GmbH and the eddy current software eddyMOTION, measurement data can be analyzed, visualized, and documented.

Based on the SL series, the SLT probes are also characterized by an ultra robust construction and a fully stainless steel housing which makes them suitable for harsh environments. The combination of a hardchrome plated shaft with 6 mm in diameter and precision bearings guarantees highest resistance to lateral forces on the push rod. There are three different functional variants available to meet the demands of most measuring tasks: ■ Spring loaded mechanism: The push rod is fully extended by an internal spring. ■ Pneumatic version 1: The push rod extends by applying pressurized air. An internal spring retracts the push rod after releasing the pressure. ■ Pneumatic version 2: The push rod retracts by applying pressurized air. An internal spring extends the push rod after releasing the pressure. Each sensor requires a carrier frequency measuring amplifier to operate, which evaluates and transforms the sensors signal to a standardised analog output signal of 0...10 V or 4...
