Schreiber SM27 Series Amplified LVDT Sensor Ø 10 mm PCD 20.0 mm
- Manufacturer: Schreiber Messtechnik
- Category: Amplified LVDTs, SENSORS, LVDT Sensors
The Schreiber SM27 miniature amplified LVDT sensor belongs to the family of LVDT with integrated electronics. It integrates an ASIC oscillator/demodulator in a 10 mm diameter stainless steel cylindrical body. Power supply: 5 V DC. Continuous analog output of 0 to 4 V proportional to the displacement of the NiFe alloy core (SM277 increasing, SM278 decreasing). No external conditioners required. Useful measurement range: 5, 10, 15, and 20 mm.
The SM27 uses the same flanges as the passive SM21 version, with a 20.0 mm PCD pattern (SM906 flange). The 0-4 V signal is applied directly to data acquisition (DAQ) cards or PLCs. Applications: CNC machinery and space-constrained test benches. Linearity: < 0.5% (standard) and < 0.25%. Protection: IP66 (connector format) and IP67 (radial injection-molded connector). Thermal drift: < 0.01%/°C (-20°C to +85°C). Shock resistance: 250 g SRS (20 Hz to 2000 Hz). More linear position sensors. Technical consultation.
