Condition MonitoringCondition monitoring is a major tool in predictive maintenance, for many areas of industry. Vibration analysis is a key diagnostic indicator in condition monitoring, especially for rotating equipment or machinery. A key aspect of this is to measure the shaft speed of rotation and phase angle accurately. Safety MonitoringMonitoring of noise or vibration signals from plant machinery or equipment under test is an important tool in protecting the safety and integrity of the equipment itself. Typical examples are for the development testing of new designs of equipment, for which predictions of vibration are available but measurements are not. Endurance TestingDuring development testing of equipment such as rotating machinery, it is often necessary to run performance or endurance testing, often lasting 150 hours or more. For situations like this, it is highly beneficial to be able to record data continuously. Data LoggingLogging data from dynamic signals is often useful for assessing the long-term behaviour of equipment. This can be done by digitising data at a higher bandwidth than is required for recording, and summarising the data prior to recording. Examples include measuring vibration responses to harmonic excitation such as tracked engine orders, or shaft centre-line on rotor dynamics. Some applications require further calculation, such as rain-flow stress-strain cycle counting. |
