SM SERIES | LVDT Inductive Position Transducer: Standard series that fits nearly all industrial and laboratory applications, highly customisable. ■ 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

LVDTs (Linear Variable Differential Transformers) are inductive sensors excellent for use in harsh industrial environments, e.g. high temperature and pressure ranges, as well as high accelerations and measuring cycles. 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. The IMCA and KAB electronics (explanation...

4 SENSOR TYPES | SM SERIES SENSOR TYPES ■ CONNECTOR / CABLE OUTPUT AXIAL / RADIAL Sensors with cable output have a cable fitting and a spring for bend protection of the cable. For installation, the bending radius should not be less than 3 times the cable diameter. The standard cable length is 2 m. Instruments with option H for temperatures up to 150 °C/ 200°C feature a PTFE cable. For normal application the sensors have a closed rear end body. Sensors that feature a radial cable output can be supplied with a through hole on request. Please use this version for applications at heavy dirt...

CABLE ELECTRONICS KAB FUNCTION CABLE PTFE-UL If not specified otherwise the cable electronics is placed at 1 m from the end of the cable. EXTERNAL ELECTRONICS IMCA external electronics IMCA (for DIN-rail mounting) The external electronics IMCA is designed to be installed in switch cabinets (Din-rail mounting). The connection to the sensor is conducted as connector with push-in spring connection. * * Terminals 1 and 7 are internally connected. ADJUSTMENT OF ZERO POINT AND GAIN Each sensor, manufacted by eddylab, is basically adjusted and calibrated. You will receive a traceable calibrated...

CABLE BREAK DETECTION The electronics by eddylab feature a built-in cable break detection. This is achieved by an impedance measurement of the LVDT´s secondary coil. If the sensor cable is cut, the impedance on the secondary connections of the electronics change regardless of the push rod position, triggering the cable break detection. This feature is based on a broken secondary connection. A partial cable break of the primary connections (cables between primary coil and electronics) will not activate this function. The electronics vary in their functional range. The external electronics...
