Affordable non-contact torque transducer avoids need for slip-rings
05 July 2011
For applications where measurements are to be taken from a rotating shaft without resorting to the use of slip rings, then the new Model 1700 Series transducers from RDP Electronics provide a cost effective solution. The comparatively low cost, non-contact, amplified, torque transducer uses a combination of optical and inductive technologies, avoiding the use of slip rings where they are not appropriate.
The output is proportional to the torque applied to the shafts of the transducer either whilst the shaft is static or rotating. The compact Model 1700 can have speed or angle sensing and has integral signal conditioning and amplification electronics with a ±10V dc output that can optionally be connected to a digital display indicator. A range of models is available up to 10,000rpm in speed sensing versions and 3,000rpm for the angle sensing option.
