A Bluetooth interface and Android app have been developed for the TorqSense non-contact torque sensor. The sensor does not have to be physically connected to the shaft that is being measured. Instead two tiny piezoelectric combs are glued onto the shaft and an adjacent radio transmitter/pickup monitors their distortion due to the shaft’s rotation, using radio frequency waves. There is no physical connection between shaft and sensor, hence no need for delicate wiring or slip rings. The Bluetooth module option brings total wireless flexibility to torque measurement. In use the module simply plugs into the TorqSense’s existing 15 way ‘D’ digital lead connector. As well as collecting the torque signal, the Bluetooth allows the transducer to be powered through the interface and also provides a USB output for connection to a PC, which allows a full version of the TorqView software to be used.
