E2X & E2F 氢气防爆压力传感器 E2X & E2F Explosion-Proof Pressure Transducer
CVD 薄膜传感器
当需要防爆或防爆危险认证时 ，Ashcroft E2X 和 E2F 压力传感器满足广泛的压力传感要求。 使用 Ashcroft 经验证的 CVD 薄膜传感器技术，可提供根据 Ashcroft 的 TruAccuracy 终点标准制造的可靠且可重复的传感器。 Ashcroft 的直接 TruAccuracy 标准消除了从统计得出的准确度规格中的混淆，并避免了在安装时进行用户校准的需要。 这使得 E2X 和 E2F 成为要求苛刻的危险工业和过程应用的理想选择。
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.
