Induktive sensors SL, LVDT

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...

■ Configurable output signal (4...20 mA, 0...20 mA, 0...5 V, 0...10 V, ±5 V, ±10 V) ■ DIN rail mounting ■ Low residual noise ■ Built-in cable break detection with alarm-output

The SLX series is derived from the SL series and has been especially for use in applications in the pharmaceutical, medical and food industries. To reduce machine downtimes, CIP and SIP ("cleaning in place", "sterilization in place") cleaning and sterilization processes are state of the art today. For this purpose, the machine interior is cleaned thermally and/or chemically with high temperature, pressure and aggressive media. The devices of the SLX series are perfectly equipped for use in this area and guarantee maximum reliability and service life thanks to their extremely robust design, a completely sealed stainless steel housing and high media and temperature resistance.
