What to Consider When Choosing Piezoelectric Vibration Sensors for Marine Engines?

1. Core Performance Parameters Temperature Range – The Primary Consideration! It is essential to select a high-temperature dedicated piezoelectric accelerometer. Confirm the sensor’s “operating temperature range”, not just the storage temperature. Ensure its upper limit is significantly higher than the actual maximum temperature at the installation point. For extremely high temperature measurement points (>180°C), consider … Read more
