Optical Torque Transducers Catch The Spin

Providing precise dynamic measurement of rotary and static torque less than 100 Nm for bandwidths of up to 50 kHz, ST Sensor Technology’s TorqSense ORT 230/240 torque sensors replace the E200 ORT series. They add electronics that produce significant performance gains in resolution, frequency response, reduced sensor current consumption, and faster digital data throughput. Overall features include:

  • Low inertia – High Speed capability because electronics are not fixed onto shaft
  • Non-contact/brushless measurement
  • High Bandwidth
  • 200% safe mechanical overload
  • Excellent noise immunity
  • 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
  • Lifetime warranty

 

TorqSense ORT230 Series transducers offer:

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.
  • 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  

TorqSense ORT240 Series transducers offer:

  • 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 users to change 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  

For further details, a plethora of resources abound including the Datasheet, Manual, Installation Guide, Communications Protocol, CANbus Manual (ORT240), and DLL Programmers’ Guide (ORT240).
