2008年3月13日消息，艾默生過程管理公司已宣布推出其SIL3的加強版，被鑒定的Fisher®FIELDVUE®SIS DVC6000數(shù)字閥。此次性能的增加可幫助改善可靠性、靈活性和緊急停車閥解決方案的實用性。ESD最終控制系統(tǒng)部件由安全的經(jīng)驗證的傳感器和SIL3額定系統(tǒng)和艾默生數(shù)字智能SIS解決方案整合而成。 艾默生過程管理公司Fisher部門主管Alfred Lee說：“安全性是第一個為我們的過程用戶考慮的。利用智能SIF的DVC6000SIS數(shù)字閥控制器，艾默生能夠完全滿足這些需求。DVC6000 SIS儀器結(jié)合在線診斷功能，可診斷SIS閥，以保證其在需求之上的實用性，還能預(yù)防spurious trips協(xié)議。 DVC6000 SIS儀器增強版包括手動重啟，儲藏安全需求事件日志，在部件撞擊測試后得知通過狀態(tài)是否正常，并通過了第三方證明，如SIL3和SIF回路證明。 安全需求事件可被存儲在處理器的非易失性存儲器中，并且可在任意時間恢復(fù)數(shù)據(jù)。此事件日志對于工廠人員，工程師來說都至關(guān)重要，審查專家也能夠真實地了解事件的最初和最終結(jié)果。 在完成部分沖擊測試之后，DVC6000 SIS儀器將提供一個帶有簽名曲線的狀態(tài)圖。其還將提供額外的粘滑運動診斷，軸的完整性和轉(zhuǎn)矩的最大化和最小化。 DVC6000 SIS數(shù)字閥控制器可由一個輸入為0-24VDC, 0-20 mA或4-20 mA的信號進行控制操作。此儀器已經(jīng)過第三方的驗證，符合IEC61508標準，并適用于SIL3，SIF回路。此儀器還適用于嚴酷離岸環(huán)境中的不銹鋼架構(gòu)，嚴格的服務(wù)架構(gòu)提供遠程安裝能力和適應(yīng)極端溫度的性能。 艾默生智能SIS安全管理解決方案是其PlantWeb®數(shù)字工廠架構(gòu)的擴展，為完整的安全回路提供完整的方法，從傳感器到邏輯解決到最終的控制元件，全部涉及在內(nèi)。艾默生過程解決方案能使用戶在運行設(shè)備時更安全，實用性得到改善、低使用周期成本及緩和的調(diào)整適應(yīng)。智能SIS系統(tǒng)部件包括Rosemount 和Micro Motion設(shè)備，DeltaV™ SIS系統(tǒng)，配有FIELDVUE DVC6000 SIS 控制器的SIL-PAC最終控制解決方案，及AMS®組件：智能設(shè)備管理器。 想知道更多關(guān)于艾默生智能SIS信息，請登錄http://www.emersonprocess.com/SIS [font=times]original text [/font] [font=times][color=#708090]Marshalltown, IA （March 13, 2008） - Emerson Process Management has announced enhancements to its SIL 3 certified Fisher® FIELDVUE® DVC6000 digital valve controller for Safety Instrumented Systems （SIS）. The enhancements help improve reliability, flexibility, and availability of Emergency Shutdown （ESD） valve solutions. The ESD final control system components are integrated with safety-certified sensors and SIL3 rated systems in Emerson‘s digital smart SIS solutions. "Safety is a major concern with our process industry customers. Emerson is able to address these safety needs with smart Safety Instrumented Function （SIF） loops that use its DVC6000 SIS digital valve controller," said Alfred Lee, director of FIELDVUE and positioning instruments for the Fisher division of Emerson Process Management. "The DVC6000 SIS instrument incorporates on-line diagnostics and partial stroking that diagnose the SIS valve to ensure its availability upon demand and also provide protections against spurious trips." The DVC6000 SIS instrument enhancements include manual reset, a stored safety demand event log, pass / fail status after a partial stroke test, and third party certification to SIL3, SIF loop. A safety demand event can be stored in the non-volatile memory of the microprocessor and retrieved at any time. This event log is critical for plant personnel, reliability engineers, and auditing authority to properly understand the final element status before and after the trip or demand event. After the completion of a partial stroke test, the DVC6000 SIS instrument will provide a pass or fail status along with a signature curve. It will also provide additional diagnostics on stick slip, shaft integrity, and maximum and minimum torque. The DVC6000 SIS digital valve controller can operate by an input signal of 0-24VDC, 0-20 mA, or 4-20 mA. The instrument is certified by a third party for its compliance to IEC61508 requirements enabling the device to be suitable for use in SIL3, SIF loop. The instrument is also available in stainless steel constructions for harsh offshore environments and severe service constructions providing remote mount capability and extreme temperature functionality. Emerson‘s smart SIS safety management solution is an extension of its PlantWeb® digital plant architecture, providing an integrated approach to complete safety loops — from sensor to logic solver to final control element. The Emerson SIS solution enables customers to implement safer facilities, improve availability, lower life-cycle costs, and ease regulatory compliance. The smart SIS system components include Rosemount and Micro Motion certified and proven-in-use devices, the DeltaV™ SIS system, SIL-PAC final control solution with FIELDVUE DVC6000 SIS controller, and the AMS® Suite: Intelligent Device Manager.
