Inductive Sensor SLX, LVDT

The SL series offers ultimate reliability and precision in a small size, and is designed for industrial and lab use. The sensors can also be used under water because of their high protection class and the stainless steel housing. ■ Measurement ranges 10...600 mm ■ Housing ø20 mm ■ Linearity up to ±0,10 % of full scale ■ Protection class IP67, optional IP68 ■ Sensor working temperature up to 200 °C ■ External, or cable electronics with cable break detection ■ Customized versions available ■ Predestined for use in harsh industrial enviroments

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

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...

he greatest challenge in the use of inductive displacement transducers is the optimization of linearity. Usual linearity deviations are around 0.30 % of the measuring range of the sensors. Values that are significantly below this can hardly be realized. With the help of the LVDT digital controller from eddylab, to which either one or two sensors can be connected, the linearity deviation of inductive displacement transducers can be almost completely eliminated.
