Abstract
A process variable transmitter for use in an industrial process control or monitoring system includes a transmitter housing and a process variable sensor having a sensor output related to a process variable. An accelerometer is coupled to the transmitter and provides an accelerometer output related to acceleration. Diagnostic circuitry provides a diagnostic output as a function of the sensor output and the accelerometer output.
