How long do piezoelectric sensors last?
Piezoelectric sensors are solid state sensors with no internal moving parts to wear or fatigue. Mean Time Between Failure (MTFB) analysis for typical industrial sensors predicts a life of 12 years. However, many sensors returned to Wilcoxon for re-calibration are more than 30 years old and still operating. While many sensors do indeed last beyond a decade, empirical data suggests an average life of approximately 15 to 20 years. If a sensor is continuously operated to the full limits of their environmental specifications, then their life span can be decreased. Sensors exposed to high temperatures (> 200ºF) and rough handling are candidates for earlier failures than those permanently mounted in benign environments.
