Linear variable differential transformer displacement sensors have nearly unlimited mechanical life because the internal core moves without friction or wear. Their excellent linearity and rugged-environment resistance make them the preferred choice for aircraft flight control systems, nuclear power plant valve position feedback, and precision laboratory deformation monitoring, with unmatched performance in high-frequency reciprocating motion.
The SensorsX SX-DLNC series uses LVDT electromagnetic sensing for linear displacement and position measurement. Ranges, outputs, and configurations vary by model.
Measurement Range: 2–500 mm, depending on model.
Repeatability / Resolution: ≤0.01% FS or 1 μm, model-dependent; resolution down to 0.1 μm; digital output: 16-bit.
Linearity Error: ±0.25%, ±0.35%, ±0.5%, or ±2% FS, depending on model.
Output / Power Supply: 0–5 V or digital: 9–28 VDC; two-wire 4–20 mA: 15–28 VDC. AC excitation: 1–3 Vrms, 5 kHz. Pen types require an external transmitter for DC or RS-485 output.
Configurations: Split-type, spring-return, pneumatic, pen-type, explosion-proof, valve-spool, gap displacement, and crack meter.
Connection: Direct cable or connector; shielded TPU cable, Ø3 or Ø4 mm; 1, 2, or 5 m.
Service Life: Over 10 million cycles on applicable models.
Temperature / Protection: −25 to +85 °C; high-temperature valve-spool version: −40 to +125 °C. IP64, IP65, or IP67, configuration-dependent; pen-type rating unspecified.
