Linear LVDT Schreiber Series SM26 and SM28
- Manufacturer: Schreiber Messtechnik
- Category: Displacement, LVDT, LVDT Unamplified, SENSORS
He Linear LVDT The Schreiber SM26 and SM28 series is the high-performance standard for displacement measurement in extremely confined spaces. With a housing diameter of just 10 mm In the SM26 series, this inductive transducer offers infinite resolution and frictionless mechanical durability thanks to its free magnetic core. Its design is optimized to ensure a signal stability and EMI immunity Exceptional, being the preferred solution for integration into servo valves, pneumatic actuators and process control systems where space is a critical resource.
This displacement transducer It has been designed to offer a 1:1 compatibility / drop-in replacement In industrial machinery requiring a technological upgrade without modifying the original mechanical design. Thanks to its protection IP68 with cable output and connector option M12 (Binder 723 series), the SM26/SM28 withstands vibration conditions up to 20g and shocks of 250g. Its inductive half-bridge technology requires external amplification (SM10/SM12 series), allowing data acquisition to be separated from electronic processing for maximum reliability in harsh environments.
