The system utilizes a digital memory component of the RFID transponder to record and maintain historical measurements to aid in determining machine condition trending. The RFID transponder interacts with a machine condition advisor (MCA), where the MCA obtains a configuration and historical data from the RFID transponder, queries sensors, collects data, transfers updated data to the RFID sensor, and determines and displays condition trending. Machine condition trending can be displayed in a graphical format. Warning or alarm levels can be established enabling the system to determine machine conditions warranting alerting a machine technician. Each machine condition trending can be independent of or associated with the associated warning or alarm level.
