Fast and accurate torque measurement is becoming more and more important in a variety of manufacturing sectors for process automation and to optimize productivity. Setting a new benchmark for digital torque measurement, Sensor Technology has launched a new series of optical rotary torque transducers ideal for applications when the demand is for low torque and/or high bandwidth.

The sensors claim to provide precise, dynamic measurement of rotary and static torque of less than 100Nm and for bandwidths of up to 50kHz. 

Applications for these torque sensors include: food and chemical mixing, engine and turbine power measurements, measuring peel forces, friction, and bottle cap torque, spring testing, ISO 9000 and other quality control during manufacturing, screw and assembly machine logging.

Key benefits of the sensors include:-

  • Low inertia – High-Speed capability because electronics are not fixed onto shaft.
  • Non-contact/brushless measurement ensures long life and reliability with high accuracy.
  • Excellent noise immunity due to the optical operating principle
  • Units are backed by a lifetime warranty.
  • High Bandwidth upto 50kHz.
  • 200% safe mechanical overload
  • Separate digital electronics
  • Operates both statically and dynamically
    – clockwise/anti-clockwise
  • Any full-scale torque can be specified within standard range: 10mNm through to 100Nm

Key features of the TorqSense ORT230 Series transducers include:

  • Fixed voltage or current analog outputs (one for torque and the other for speed or power) for interfacing with analog instrumentation
  • BIT Self-diagnostics for letting the manufacturer know that the transducer’s torque, speed ratings and calibration due date have not been exceeded
  • Simple ‘Sensor status’ output pin
  • Sensors to monitor shaft temperature for better compensation and accuracy

Key features of the TorqSense ORT240 Series transducers include:

  • Digital outputs, such as RS232, CANbus and USB, for interfacing with modern instrumentation and laptops
  • Digital input for configuring transducer via PC
  • 2 x user selectable voltage or current analog outputs (one for torque and the other for speed, power or peak torque) for interfacing with analog instrumentation
  • Transducer configuration software to allow user to changes transducer variables
  • BIT Self-diagnostics for letting users know data is trustworthy, that the transducer’s torque, speed ratings and calibration due date have not been exceeded
  • Simple ‘Sensor status’ output pin
  • Sensors to monitor shaft temperature for better compensation and accuracy
  • Ability to connect up to 10 transducers using USB
