ABSTRACT:
A process fluid pressure transmitter includes a process fluid pressure sensor, measurement circuitry, a controller and a loop communicator. The pressure sensor is coupleable to a source of process fluid pressure. Measurement circuitry is coupled to the process fluid pressure sensor and provides a signal indicative of the electrical characteristic of the process fluid pressure sensor. The controller receives the signal from the measurement circuitry and calculates a process fluid pressure based at least in part upon the signal. The controller is also configured to detect a process fluid pressure transient and store at least one parameter related to the process fluid pressure transient. The loop communicator is coupled to the controller and is configured to provide a signal over a process communication loop based upon the process fluid pressure. The process fluid pressure transmitter is also configured to provide an indication related to the at least one stored parameter.
