What are common failure modes for pressure transmitters and their typical causes?

• A. Sensor drift due to aging; diaphragm leaks from corrosion or mechanical damage; fill-fluid migration in sealed units; clogging from particulates; wiring faults; and electronics failure.
• B. The only failure mode is a broken housing; everything else is impossible.
• C. Overheating the transmitter permanently improves accuracy.
• D. Calibration will automatically fix drift without maintenance.
