PHT120 Miniature Pressure Sensor

Operating from –40 up to +175°C, the PHT120 series is dedicated to high temperature pressure measurements. With all stainless steel wetted parts, it is compatible with most media, including corrosive fluids used in automotive, aerospace and energy industries. Equipped with the premium thin film technology developed by EFE, its performances and stability over wide temperature range are excellent. The PHT120 is available with unamplified output (mV/V), compensated in temperature to deliver the best accuracy. Amplified output (Vdc) is also standard, thanks to a high performance and rugged built-in electronic module.

Features

  • Miniature pressure sensor
  • Available with 0,5-4,5Vdc output
  • Robust and reliable sensor
  • Operating from -40 to +175°C

Applications

  • Oil & gas
  • Automotive – on vehicle
  • Aerospace
  • Military

The EFE Engineering Department is responsible for designing all our sensors, from sensing elements to state of the art PCBs. To meet the customer’s high requirements, EFE decided very early on to develop its propriety sensing technology for pressure transducers. This technology, thin film, is manufactured mainly using a physical vapour deposit, and more precisely sputtering process on a metal diaphragm (stainless steel, titanium, inconel, hastelloy, etc.). This film is used by EFE is the only technology which does not require any intermediary between the sensing element and the fluid to be measured as with an oil separator for silicon based sensors or O-rings for ceramic technology.
