SX-FTFNB Series

The SensorsX SX-FTFNB series is a double-flange static torque sensor designed for static and reaction torque measurement. It suits applications that do not require continuous rotation. Rated capacities range from 10 to 20,000 N·m. The sensor provides a 1.0 mV/V output and features stainless-steel construction with IP65 protection. An external amplifier is required for transmitter-output configurations.

  • Capacity: 10–20,000 N·m.
  • Non-Linearity: ≤±0.1% FS.
  • Hysteresis / Repeatability: ≤±0.05% FS.
  • Output: 1.0 mV/V.
  • External Module Options: 4–20 mA, 0–5 V, 0–10 V, PROFIBUS, Modbus, CANopen or RS485; module-dependent.
  • Excitation: Recommended 5–12 V DC; maximum 18 V DC.
  • Creep: ±0.05% FS over 30 min.
  • Zero Output: <±1% FS.
  • Temperature Effects: Output and zero: ±0.05% FS / 10 °C.
  • Overload: Safe 150%; ultimate 200% FS.
  • Temperature: −30 to +80 °C.
  • Construction: Stainless steel; double-flange mounting; IP65.
  • Connection: Binder 581 series, 6-pin.
