EDC uses advanced data acquisition instrumentation to measure both static and dynamic strains across a wide range of industries and service conditions. EDC has the resources to measure signals even in the most hazardous of environments. If you think it can't be measured, chances are, it can!
Each of the Senior Engineers has over 20 years of practical strain gauge experience. Our extensive experience ensures that accurate data is always obtained.
Data Acquisition Instrumentation
- Multi-channel simultaneous high-speed data acquisition instrumentation.
- Data loggers for long term or remote data acquisition.
- Telemetry instrumentation for measurement of strain on shafts or mobile equipment.
- Multi-channel (up to 56) high speed radio transmitters for strain measurement.
Signal Processing Software
- Matlab and Labview signal processing software for site data analysis.
Strain Gauging Experience
Over the years, EDC engineers have been involved in numerous different strain gauge projects. Some of the more interesting and complex jobs have been:
- Installation and monitoring of high temperature weldable strain gauges on a kiln, blast furnace and continuous metal casting machine.
- Multi-channel strain gauge installation and measurement on many Ball/SAG mills through telemetry instrumentation.
- Similar multi-channel strain gauge installation and measurement on a reclaimer bucketwheel monitoring dynamic strains during normal operation, using radio telemetry instrumentation.
- Duty cycle monitoring of strains on mobile equipment using radio telemetry and datalogging instrumentation.
- Shaft torque strain monitoring on numerous mining/marine shafts and fans.
- Underwater strain measurement on the keel of a high-speed catamaran vessel and on the blades of an agitator.
- Simultaneous strain measurement of in excess of 80 channels of dynamic strain.
- Residual stress measurements on highly loaded structures.
Materials Strain Gauged
EDC engineers have extensive experience with static and dynamic strain measurement with full temperature compensation on:
- Steel
- Aluminium
- Plastics
- Concrete
- Stainless steel
- Fibreglass
- Polyethylene
Fatigue
Much of EDC's work involves detailed fatigue analysis, typically of welded steel structures. Through measured strain time history data and analysis, the remaining/consumed fatigue life of a machine or structure can be predicted.
Typically, a fatigue analysis would be conducted in accordance with the requirements of fatigue standards, British Standard BS 7608 or associated aspects of the Australian Standard, AS 4100.
