SX-FTRNB Series

The SensorsX SX-FTRNB series is a flange-mounted static torque sensor designed to measure static and reaction torque. Its square socket interface suits applications that do not require continuous rotation. Rated capacities range from 2 to 5,000 N·m. The sensor provides a 1.0 mV/V output and features stainless-steel construction with IP65 protection. Optional conditioned outputs are available through an external transmitter module.

  • Capacity: 2–5,000 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; flange mounting; IP65.
  • Square Socket: 1/4"–1 1/2", depending on capacity.
  • Connection: Binder 581 series, 6-pin.
