A self-contained system to continuously monitor a mechanism used to process, control or regulate fluid flow or pressure and provide a continuing indication of the status or condition of the monitored mechanism. A specific form of the invention employs a low frequency sonic-to-electrical transducer that monitors opening and closing of a disk-type steam trap. The detected sonic signal is processed and sent to a microprocessor that is programmed to develop a time-based, baseline data set representative of normal operation of the steam trap in the environment in which it operates. The baseline data set is compared with the data from on-line operations of the steam trap. As the environment and the steam trap operation change during normal on-line operations, the baseline data set is updated to change with the changing environment and the changing steam trap operation.
