Non-contact torque measurement is the theme of Sensor Technology’s stand this year. The RWT310/320 series of Torqsense Rotary Torque Sensors is now available in a full range of sizes from 1Nm to 10,000Nm, so can be applied to virtually any size of system where precise yet simple torque monitoring is required. And these are complemented with Torqview II, a software program that generates a virtual instrumentation display of the output from a Torqsense transducer that can be run on any computer.
Torqsense RWT310/320 provides non-contact measurement of torque, speed, power and position of rotating shafts, such as machine drives. It uses tiny piezo-ceramic combs fixed to the shaft that distort in proportion to the instantaneous torque level. These create data signals that are transmitted via a radio frequency coupling rather than by conventional but clumsy slip rings. Because piezo technology requires so little power, this is also supplied via the RF coupling.
Each sensor includes an on-board alphanumeric readout for data collection. However many users prefer to feed the data streams through to a PC for collection and analysis, which opens up the possibility of displaying the data on a full-sized screen. Torqview II has fully configurable and scalable graphics modules, so that the information can be presented in a number of different formats, including discrete digital readouts, analogue dials, bar graphs and so on.
