High Temperature Piezoelectrics Ceramics

Our range of high temperature materials offer increased sensitivity at higher temperatures to help you succeed in your demanding environment.

Piezoelectric sensors offer low cost, low power consumption solutions that are temperature stable in challenging environments, including oil well logging, automobile sensors, and vibration and pressure sensors for aerospace and power plant engines.

We have two materials particularly suited to high temperature situations. Our TRS 203HD can operate up to 300 oC. TRS BT200 can operate up to 350 oC.
