E2X & E2F 氫氣防爆壓力傳感器 E2X & E2F Explosion-Proof Pressure Transducer
CVD 薄膜傳感器
當(dāng)需要防爆或防爆危險(xiǎn)認(rèn)證時(shí) ，Ashcroft E2X 和 E2F 壓力傳感器滿足廣泛的壓力傳感要求。 使用 Ashcroft 經(jīng)驗(yàn)證的 CVD 薄膜傳感器技術(shù)，可提供根據(jù) Ashcroft 的 TruAccuracy 終點(diǎn)標(biāo)準(zhǔn)制造的可靠且可重復(fù)的傳感器。 Ashcroft 的直接 TruAccuracy 標(biāo)準(zhǔn)消除了從統(tǒng)計(jì)得出的準(zhǔn)確度規(guī)格中的混淆，并避免了在安裝時(shí)進(jìn)行用戶校準(zhǔn)的需要。 這使得 E2X 和 E2F 成為要求苛刻的危險(xiǎn)工業(yè)和過程應(yīng)用的理想選擇。
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.
