Intrinsically Safe Hydrogen Pressure Transducer - E2S

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.

Key features

Uses Ashcroft’s proven thin film technology

+/-0.25%, +/- 0.50% or +/-1.0% of span accuracy available

Standard ranges from vacuum to 20,000 psi and 0 to 500 psia (custom ranges available)

Rugged 316 stainless steel Housing

Diaphragm available in 17-4 PH, 316L stainless steel or A286

FM, ATEX and IECEx intrinsically safe approvals

FM non-incendive approved

4-20mA or multiple Voltage outputs available

External magnetic offset and span adjustment

CE approved

RoHS compliant intrinsically safe pressure transducer
