Torque Transducers

Flange Mounted Transducers incorporate mounting points for securely fixing the transducer to the working surface. The transducer lead is also included and is fitted with a high quality Lemo® connector, suitable for attachment to TST and TTT instruments.

  • Classified to BS7882:2017, typically better than Class 1 for the primary classification range (±0.5% of reading from 20% to 100% of full scale).
  • 'SMART' - TST, TTT, TTL-HE& T-Boxinstruments will automatically recognise calibration details.
  • Rundown Fixture is included on transducers up to 150 N·m (100 lbf·ft) allowing joint simulation for power tool testing.
  • Supplied with UKAS accredited calibration certificate.
  • Transducers are supplied with precision made square drive adaptors.

Flange Mounted Transducers

The accuracy and quality of the Norbar Static Torque Transducers has made them the first choice of many calibration laboratories throughout the world.

  • Up to 5,000 N·m (5,000 lbf·ft) classified to BS7882:2017, typically better than Class 1 for the primary classification range (±0.5% of reading from 20% to 100% of full scale).
  • Robust, heat treated, alloy steel torsion shaft design.
  • Designed to ignore non torsional forces.
  • Operates in clockwise and anti-clockwise directions.
  • Calibration up to 100,000 N·mwith a UKASaccredited Certificate.
  • Calibrated in clockwise direction as standard. Anti-clockwise provided on request.
  • 'SMART' transducers have a built in memory circuit which contains essential information about the transducer. This information can be read by Norbar's TST, TTT, TTL-HE& T-Boxinstruments meaning that when the transducer is connected, it is immediately recognised and ready for use.
  • 'SMART' transducers can also be used with many other instruments. However, these will operate as normal ratio calibrated (mV/V) transducers - the 'SMART' data will not be read.

'SMART' Static Transducers

'SMART' Static Transducers

Rotary transducers are designed to measure the torque from continuously rotating shafts such as Impulse Power Tools and certain non-impulse tools with a severe clutch action.

This new range offers an additional model of 5 N·m capacity and class leading performance with impulse tools and will be supplied with a UKAS accredited calibration certificate from Norbar's laboratory.

These trandsucers are known as 'SMART' transducers. They have built-in intelligence in the form of a memory circuit which contains essential information about the transducer which can be read by the appropriate type of instrument (TST, TTT, TTL-HE & T-Box), thus reducing set-up time.

They will also work with instruments that cannot read the memory information, by inputting the relevant calibration details manually.

Not for use with Impact Tools.

Angle measurement also available.
