How to determine if a vibration sensor is heat-resistant

Three procedures can be used to quickly determine the outcome: "parameter verification + label verification + test verification." Examining the stated temperature resistance parameters is crucial.

First, go to the "Operating Temperature Range" section of the sensor's parameter page in the product parameter manual. Its higher temperature resistance limit is the highest operational temperature that is prominently shown. It satisfies the high-temperature resistance criteria as long as the upper temperature resistance limit is ≥ hot runner operating temperature + 20°C. You must look at the continuous operating temperature parameter if just the storage temperature is indicated. The storage temperature cannot be used as the operating temperature resistance.

Verify the product's certification and labeling: Reputable industrial sensors that can withstand high temperatures will have the temperature resistance range clearly indicated on the label or casing. Industrial certifications like AEC-Q100 will be applied to products modified for automotive or industrial application. Higher dependability is shown by the well-defined temperature resistance standards that correlate to the certification level.

Simple pre-test verification (optional): For unidentified sensors that aren't labeled, put them in a chamber with a continuous temperature set to the hot runner operating temperature and leave them there for two hours. Test the output signal and continuity after removing it. It can tolerate the appropriate temperature if the signal is normal and there is no damage.

Common sensors frequently say "wide operating temperature" without providing an upper limit or purposefully hide their temperature resistance specifications. The high-temperature requirements of hot runner systems are typically not met by these kinds.
