Leaders in Engineering Solutions

Meggitt HTP origins after the divestures of low temperature activities related to the Endevco brand.
In fact Meggitt Energy Equipment retained all products with operative capabilities above 260°C As a leading provider of pressure and vibration sensors for the most demanding aerospace, nuclear, turbine and industrial control measurement applications,
Meggitt’s advanced sensors are specialized to withstand the challenges of extreme environments.

Over a half century of high temperature innovation from Meggitt
– 1970’s First high temperature (900°F, 482°C ) piezoelectric crystal developed
– 1980’s First tourmaline sensor developed (1400°F, 760°C)
– 2019. Higher temp sensor developed (1500°F, 815°C)

What makes them unique in the market:

  • Long term, stable performance
  • Small size & lightweight
  • Proven, reliable design and manufacturing legacy
