2400S現(xiàn)可與DeviceNet 和PROFIBUS DP通信相配套一起使用,提高ELITE® Coriolis儀表 COLO,BOULDER2008年8月26日消息，艾默生過程公司已經(jīng)推出供Micro Motion® 2400S傳送儀使用的通信選擇權。這些緊湊型產(chǎn)品，可整合安裝在Micro Motion ELITE® Coriolis傳送儀上，可與除像4-20 mA，HART®的傳統(tǒng)界面之外的DeviceNet或PROFIBUS DP 通信協(xié)議相適應。 DeviceNet和PROFIBUS DP被廣泛用于許多行業(yè)和應用PLC的過程應用，帶有PLC的直接數(shù)據(jù)通信意味著兩根線就可以執(zhí)行二級和三級過程變量、儀器儀表/過程診斷信息，以及初始測定。通過單一設備，排除多重傳感器和布線/配置成本的需求，提供流量、密度和溫度測量，將全功率的Micro Motion Coriolis流量和密度設備帶給用戶的主機系統(tǒng)。此外，數(shù)字化通信開啟了儀器診斷信息時代，如drive gain，儀表確認和其它報警器。 新通信選擇權使Micro Motion 2400S傳送器在采用各種不同標準的全球操作市場上很受歡迎，對于OEMs來說更是非常理想的選擇，傳送計提供了一個簡單且快速的界面，與現(xiàn)存PLC架構一起成為直接數(shù)字通信的額外受益。因為2400S傳送器被整合在了Micro Motion ELITE傳感器上，其很容易安裝和使用，由于具備可選擇的顯示器，可以隨時了解過程變量和診斷信息。在原位，儀表確認還可以從2400S傳送儀處獲得，允許用戶在四分鐘以內(nèi)執(zhí)行完整的流量檢查，排除了由傳統(tǒng)儀表測試導致的中斷，保證了儀表能夠按工廠規(guī)范執(zhí)行。 除增加了通信選擇權，2400S傳送儀可被裝在指定的316L不銹鋼盒里，作為標準的鍍鋁聚亞安脂盒的另一種選擇，額定的IP66和IP67，防腐蝕不銹鋼盒在應用中非常合適，例如，應用在食品餐飲和生命科學行業(yè)，及其它苛刻的環(huán)境，如海運業(yè)和離岸操作。 Micro Motion 2400S傳送儀擁有C1D2和Zone 2，擁有最新的MVD™數(shù)字化過程處理技術，該技術可提供加強的精確性，穩(wěn)定性和多功能性。困難的應用由于快速響應時間變得方便容易，處理高度加氣處理的能力和內(nèi)置的智能診斷就能在問題發(fā)生前提前報警?！? [font=times]original text [/font] [font=times]Emerson announces new communication interfaces for Micro Motion® Coriolis flow transmitter[/font] [font=times][color=#708090]Model 2400S transmitters are now available with DeviceNet and PROFIBUS DP communications, increasing the versatility of ELITE® Coriolis meters BOULDER, COLO （August 26, 2008） – Emerson Process Management has introduced new communication options for the Micro Motion® 2400S transmitter. These compact devices, which mount integrally onto Micro Motion ELITE® Coriolis meters, are now available with DeviceNet or PROFIBUS DP communication protocols in addition to the traditional interfaces such as 4-20 mA, frequency and HART®. DeviceNet and PROFIBUS DP are widely used across many industries and processes with PLCs. Direct digital communications with the PLCs means that two wires can now carry secondary and tertiary process variables and instrument/process diagnostic information, as well as the primary measurement. This brings the full power of Micro Motion Coriolis flow and density devices into the user‘s host system by providing flow, density and temperature measurements through a single device, eliminating the need for multiple sensors and the wiring/configuration costs associated with them. In addition, digital communications unlock instrument diagnostic information, such as drive gain, meter verification and other alarms. The new communication options make the Micro Motion 2400S transmitter ideal for OEMs operating in global markets, where different communications standards are often employed. The transmitter provides a simple and fast interface with an existing PLC architecture together with the added benefits of direct digital communications. Because the 2400S transmitter mounts integrally on Micro Motion ELITE sensors, it is easily installed and commissioned, with an optional display showing process variables and diagnostics at a glance. In situ meter verification is also available with the 2400S transmitter, allowing users to perform a complete flow meter check in less than four minutes. This eliminates disruptions caused by traditional meter tests and ensures that the meter is performing to factory specification. In addition to the increased range of communication options, Model 2400S transmitters can now be specified with a 316L stainless steel housing as an alternative to the standard polyurethane-painted aluminum housing. Rated to IP66 and IP67, the corrosion resistant stainless steel housing is ideal for applications, where instruments are subjected to regular caustic wash-downs, for example as found in the food & beverage and life science industries and other harsh environments such as marine and offshore. The Micro Motion 2400S transmitter has C1D2 or Zone 2 approvals and features the latest generation MVD™ digital processing technology which provides enhanced accuracy, stability and versatility. Difficult applications become easy with ultra-fast meter response time, the ability to handle high degrees of air entrainment, and built-in smart diagnostics that alert you to problems before they impact the process.
