Schreiber SM22 Series Compact LVDT Sensor | Accuracy within 10mm Ø
- Manufacturer: Schreiber Messtechnik
- Category: Displacement, LVDT, LVDT Unamplified, SENSORS
He compact LVDT sensor The Schreiber SM22 series is the benchmark in precision engineering for space-critical applications. With a housing diameter of just 10 mm and a standard 8 mm clamping stem (h8 tolerance), this inductive transducer offers infinite resolution and superior thermal stability (< 0.005%/°C). Constructed from stainless steel and nickel-iron alloys, the SM22 is designed to withstand the most demanding conditions, ensuring protection up to IP68 in its airtight configuration.
For advanced metrology applications, the variant SM224 (Microprobe) It incorporates high-precision ball bearings and a Viton bellows, achieving an astonishing repeatability of 0.15 µm. Thanks to its mechanical and electrical compatibility with standards from brands such as Tesa, Solartron, and Mahr, the SM22 allows update measurement systems with PLC directly and economically. Its robustness against shocks of 250g and vibrations of 20g makes it the perfect ally for quality control in automated production lines.
