Drive shafts and prop shafts transmit power in machinery throughout the world. In many cases they are driven to the limits in applications such as motor-sport or subject to occasional overload in applications such as factory drive systems.
Whatever the application an accurate and simple measurement of the torque transmitted can be invaluable to improve designs, protect the machinery and monitor or control its performance. The two systems offered by Datum Electronics provide effective on-shaft torque monitoring which will fit a wide range of shafts, which type will vary depending upon your requirements.
The first is the Series DSTT420 which is designed to fit on to permanent installations and is self powered. The second is the Series DSTT430 which is designed to be used as a trails kit, which is powered by batteries, which uses short range telemetry technology transmitted to a receiver.
Series DSTT420
Series DSTT420 is our ‘permanent’ solution which is self-powered, allowing the transducer to be installed on the majority of drive shafts and is robust enough to work in harsh environments. There is no need to move or disrupt the equipment connected to the drive shaft, we can install directly on to the shaft. This is the recommended option for continuous condition monitoring.
Series DSTT430
Series DSTT430 is our Trials version of the permanent solution. The Series 430 is battery powered and a completely self-contained shaft unit that uses short range telemetry technology to transmit the digital data to a receiver. The receiver has a transmission range of up to 30 metres and can sample raw data at 300 samples per second. The battery can replaced or re-charged as and when necessary
Specifications
The Drive Shaft Torque transducers have a system accuracy of 0.1% to 0.25% depending upon the size and Diameter of the shaft. The level of torque being measured is again dependant upon shaft size with the diameter ranging from 20mm up to 400mm. It outputs in digital data (RS232) with an output of 4-20mA or 0-10VDC as required.
