FOXBORO PH/ORP傳感器871A系列介紹
871A-1和-2(標(biāo)準(zhǔn))傳感器設(shè)計(jì)用于873PH和873DPX分析儀,也可以與875PH分析儀和870ITPH變送器一起使用。
871A-3和-4(智能)傳感器設(shè)計(jì)用于875PH智能分析儀和870ITPH智能變送器。它們提供了在線診斷的附加功能,以在出現(xiàn)幾種常見傳感器故障中的任何一種時(shí)向用戶發(fā)出信號(hào)。這些傳感器可以通過多種方式安裝到過程中。它們?cè)陔姌O和電纜末端都有1英寸的外部NPT連接。傳感器可以直接插入到生產(chǎn)線中,也可以通過各種附件將傳感器連接到其他標(biāo)準(zhǔn)管道尺寸。通過將傳感器電纜端的1英寸NPT連接耦合到所需長度的1英寸管道,然后將組件降低到要監(jiān)視的過程中,就可以在堰,水渠,池塘和水箱中進(jìn)行現(xiàn)場安裝。
這些傳感器采用密封的電極設(shè)計(jì),消除了對(duì)電極系統(tǒng)完整性的擔(dān)憂。當(dāng)與智能分析儀或變送器一起使用時(shí),智能傳感器設(shè)計(jì)可以向用戶發(fā)送信號(hào),告知其電極系統(tǒng)完整性是否丟失或破壞。所有傳感器均經(jīng)過工廠測試,以確保安裝時(shí)具有適當(dāng)?shù)男阅堋?/p>
The 871A-1 and -2 (standard) Sensors are designed for use with 873PH and 873DPX Analyzers.They can also be used with 875PH Analyzers and 870ITPH Transmitters.
871A-3 and -4 (intelligent) Sensors are designed for use with 875PH Intelligent Analyzers and 870ITPH Intelligent Transmitters. They provide the additional capability of on-line diagnostics to signal the user if any of several common sensor faults occur. These sensors may be mounted to the process in a number of ways. They have a 1-inch external NPT connection on both the electrode and cable end. The sensors can be inserted directly into the process line or through a variety of accessories that adapt this connection to other standard pipe sizes. In-situ mounting into weirs, flumes, ponds and tanks is achieved by coupling the 1-inch NPT connection at the cable end of the sensor to the required length of 1-inch pipe and then lowering the assembly into the process being monitored.
These sensors, with their sealed electrode design, eliminate concerns of electrode system integrity.The intelligent sensor design, when used with the intelligent analyzer or transmitter, signals the user if electrode system integrity is lost or destroyed. All sensors are factory tested to ensure proper performance upon installation.
