Abstract
An apparatus and a method monitor condition of a temperature measurement point in an industrial process system by sensing vibration frequency of a thermowell positioned in a process fluid flow passage and providing a diagnostic output based upon the vibration frequency sensed. The apparatus includes a temperature measurement point having a thermowell, a vibration sensor, a temperature sensor, and a transmitter. The vibration sensor is fixedly attached to the thermowell, and the temperature sensor is positioned inside a bore cavity of the thermowell. The transmitter is electrically connected to both the temperature sensor and the vibration sensor.
