On-shaft torque monitoring for wide range
The two systems offered by Datum provide effective on-shaft torque monitoring, which will fit a wide range of shafts, which type will vary depending upon users' requirements.
New developments within the signal processing and transmission elements of our torque sensors have greatly enhanced our capability, reliability and product worth.
The Series 420 torque transducers have been designed to fit into drive systems and are able to provide enhanced and more detailed information on transmission characteristics within the drive train itself.
Datum Electronics are providing the transducers of the future, for the industries of the future, by combining the latest technology and design features with the ability to fit into the most stringent spatial constraints.

Strain gauge amplifiers provide load cell data
Strain gauge amplifiers provide serial data from one or more load cells and can supply either scaled or raw data from one, two, four or eight load cells - linked directly into a PC workstation.
This new technological capability has provided us with the tools to measure high frequency torsional changes within a transmission system.
Such changes will allow further analysis into enhanced characteristics.
These include torsional vibration - out of balance and unwanted drive vibration components; torsional ripple - gear meshing, blade cycling and offset loading, plus dynamic events including gear changes, braking and acceleration.
In order to analyse these transient events, measurement capabilities have been extended and can now measure data at 15KHz in burst mode and 5KHz in continuous mode.
Selective measurements of small fluctuations in data as low as 1:10,000 of the full shaft torque range are achievable, giving optimum measurement performance and data analysis.
The data can be made available in graphical, analogue or digital formats as required.
Datum Electronics can advise on the most efficient system to provide performance data from your transmission line and provide data analysis in a clear and precise format.
One example of this being used in the field, included long term gear box testing of teeth wear within a drive system.
The solution offered provided the capture of torsional meshing data from the input and the output of a gearbox under test conditions.
From the results of the tests, analysis of the shape of torsional profile, or the teeth as they mesh, could be seen and understood.
Bursts of data were taken periodically over the life of the gearbox providing on-going data for the end user.
The ability to gather this form of dynamic data at 60,000 samples per second from the shaft gave an early indication of the change of the gear conditions and allowed additional analysis to be conducted relating to the input and output work cycles through the gearbox.
