A rotating equipment monitoring device includes a set of sensors, such as temperature, speed, pressure, and vibration sensors, locally connected to a diagnostic unit having a plant communication interface and a processor that implements one or more diagnostic routines. The diagnostic unit collects data from the sensors and performs diagnostics thereon to detect actual or potential problems with the rotating equipment on a continuous or semi-continuous basis. Using the communication interface, the diagnostic unit automatically sends signals indicating detected conditions of the rotating equipment to a maintenance system or a control system via standard or common communication network, such as a HART or Fieldbus network. The diagnostic unit may also be intermittently coupled to an off-line computer, such a one associated with a service provider, who may verify or further define the diagnostics provided by the diagnostic unit.
