Continuous online monitoring is available to large and small facilities alike. For facilities that have a control or monitoring system which accepts 4-20mA analog signals, such as a PLC or DCS, these analog input channels are all that is needed to add the benefit of vibration monitoring to your process control. Plants that do not have an existing process monitoring system in place can use the relay capability present in the iT301 or monitor the dynamic output through the use of a data collector.
Moreover, trending of the overall vibration level does not require any sophisticated analysis skills. Observing a sustained increase in overall vibration usually provides enough evidence to warrant a more detailed inspection of the machine.
