TORQUE MEASUREMENT

ANNULAR TRANSDUCERS
Calibration details

These Annular Transducers are designed to fit directly to Norbar torque multipliers and will
accurately measure the torque output from the gearbox, via a display instrument (instrument
supplied separately, see pages 93 - 94 & 96).
• Up to 6,000 N�m 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 tube design
• Designed to ignore non-torsional forces
• 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-Box™ 2 instruments
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
