Explosion-proof hydrogen pressure transducer E2X & E2F
- The Ashcroft E2X and E2F pressure transducers fulfills a wide spectrum of pressure sensing requirements when explosion or flameproof hazardous approvals are required.
- Using Ashcroft’s proven CVD thin film sensor technology provides a reliable and repeatable sensor manufactured to Ashcroft’s TruAccuracy terminal point standard.
- The Ashcroft’s straight forward TruAccuracy standard eliminates confusion from statistically derived accuracy specifications and avoids the need for user calibration at the time of installation.
- This makes the E2X and E2F ideal for demanding hazardous industrial and process applications.
