Redefining Extreme Sensing: How Piezocryst’s GaPO₄ Technology Delivers Precision Under Fire

Hydrogen combustion environments present unique challenges for pressure sensing –extreme temperatures, rapid thermal gradients, and high vibration can cause conventional sensors to fail. HBK addresses these issues with gallium phosphate (GaPO₄) technology, a material that maintains stable piezoelectric properties up to 1,000°C and resists hydrogen-induced degradation, making it ideal for turbine development, combustion monitoring, and other high-stress applications. In this article, Christian Röthel, Product and Sales Manager at Piezocryst by HBK, shares insights into how this technology is shaping the future of extreme environment measurement.
