Request Information
The Ashcroft® E2S pressure transducer fulfills a wide spectrum of pressure sensing requirements when intrinsically safe or non-Incendive hazardous approvals are required. Using Ashcroft®'s proven CVD thin-film sensor technology provides a reliable and repeatable product manufactured to Ashcroft®'s TruAccuracy terminal point standard. Ashcroft®'s straightforward TruAccuracy standard eliminates confusion from statistically derived accuracy specifications and avoids the need for user calibration at the time of installation. This makes the E2S ideal for demanding field applications.
