Test and Measurement
Another cornerstone of BMT WBM's approach in assisting clients with machinery problems is the use of diagnostic measurements under actual operational conditions.
Machinery problem diagnostics
BMT WBM has a very comprehensive range of sophisticated instrumentation and recording equipment for measuring critical parameters such as loads, stresses and hydraulic pressures. Measurements of this kind often provide the key to diagnosing the cause of machinery problems or failures and they provide the best possible basis for re-engineering to fix a problem.
Performance, safety and design verification testing
An independent testing service for customers wishing to verify the performance, safety or design of both new and existing machines.
Stress Measurement/Strain Gauging
BMT WBM has the capability and extensive knowledge necessary to measure the strain and vibration of static structures during load tests or ordinary operations. These structures to date have included concrete girder and steel road bridges, steel railway bridges, mining infrastructure and longwall mining subsidence affected infrastructure. The measurements can be used to determine the behaviour, adequacy or redundancy present in the structure. Natural frequencies can be determined through bump tests and accelerometer arrays.
BMT WBM has vast experience in troubleshooting measurements on dynamic machinery or equipment. The strain measurements can be used to determine the safety of the design and the nature of the load, and post-processed to determine the component or structures’ fatigue life and other design factors. Accelerometers are used to monitor vibration levels, and can be used in conjunction with strain measurement to determine the loading circumstances. BMT WBM has been involved in many diverse projects, ranging from boats and ships, mobile mining plant, industrial process machinery, freight and passenger trains and wind turbines. The instrumentation is configured to allow the plant to be operated as per usual, in order to allow relevant recordings.
Vibration monitoring
Advice, interpretation, hardware or software supply, or total program management. For the more complex and difficult vibration problems, BMT WBM provides powerful multi-channel measurement and analysis to identify the source of problems and their solutions.
Long term on-line monitoring, data logging
For problems which only occur intermittently, and for capturing long term trends, BMT WBM provides on-line data loggers programmed for the specific requirements of each problem.
Remote interrogation
For critical items of equipment, a low cost communication link to a site office or to one of BMT WBM's offices allows rapid, effective interrogation and very cost effective management of a condition monitoring program.
Testing of rotating machines
BMT WBM specialises in measurement of torque, stress and vibration on rotating machines, using radio telemetry links to transmit the measurement data to a recording station.
Special purpose test instrumentation
The company maintains an electronic design and build capability. Where the constraints imposed by a particular machine require a novel approach, BMT WBM provides purpose-built transducers and instrumentation.
