Rotary transducers are designed to measure the torque from continuously rotating shafts. 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 calibration certificate from Norbar's laboratory. These transducers 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.
