Product overview
Monad’s Rotary Transformer (Inductive Loop) Torque Sensor, are suitable for laboratory applications as well as industrial environments because of their compact size and multiple mounting options. Current models include either shaft or square drive styles. The contactless transmission of supply voltage and measuring signal enables continuous operation with low maintenance
For higher speed (rpm) torque measurement applications the rotary transformer system might be used. The rotary transformer system consists of two coils, one static coil that is attached to the transducer''s housing and one rotating coil that is attached to the transducer shaft. This offers the distinct advantage of there being no contact between rotor and stator and incorporates both transmission of power to and signal back from the rotating strain gauge bridge circuit. Rotary transformer type torque sensors offer typical inaccuracies of ±0.2% and are capable of speeds up to 50,000rpm.
The rotary transformer system is versatile enough for use in special torque transducers and those where space is limited. However as this design incorporates bearings, the maximum rpm is more than the slip-ring design but limited by the maximum specified performance of the bearing. The system can also be susceptible to noise and errors, which are induced by the alignment of the transformer primary-to-secondary coils. Because of the special requirements imposed by the rotary transformers, specialized signal conditioning is also required in order to produce a signal acceptable for most data acquisition systems.
