SENSOR Technology has updated TorqSense, its non-contact digital torque measuring system.
TorqSense now incorporates an integral sprocket or pulley for easier mounting in machinery such as drum mixers, generators, pumps, dynamometers and conveyor drives.
Earlier models of TorqSense provided an in-line shaft for connection to the equipment under test which made them complicated to mount.
The new RWT 350/360 TorqSense is suitable for virtually any plant driven by a belt or chain drive, particularly those where space is limited or access restricted.
Belt and chain drives naturally have a high radial load, which has to be accounted for when mounting a standard TorqSense. The RWT350/360 replaces an existing pulley/sprocket, and can be fitted quickly and automatically compensates for the radial load.
The RWT350/360 has its control electronics separate from the sensing head which means that the head can be located in very small spaces, while the electronics are mounted at a distance via a dedicated cable.
TorqSense uses tiny piezo-ceramic combs, known as surface acoustic wave devices fixed to a purpose designed flange. These distort in proportion to the instantaneous torque level. The distortion creates RF data signals that are transmitted via a non-contact radio frequency coupling rather than by conventional slip rings, or high inertia rotary transformers.
This data signal in turn is transmitted to the control unit, from which it can be read on an alpha-numeric display or transferred to a PC for storage and analysis using the TorqView software programme.
