加利福尼亞州洛杉磯 - 工業控制制造商Barksdale很高興地宣布推出其首款采用HART通信協議的數字壓力變送器系列：BiT系列。我們的新型BiT是Barksdale智能變送器的縮寫，有兩個產品系列：450X系列，帶防爆額定外殼，專為石油和天然氣行業的危險區域應用而設計;和450系列，專為高壓測試和測量以及一般工業應用而設計。


BiT系列450和450X是我們新系列高壓變送器的一部分，采用先進的電子和傳感技術設計，以保持穩定性，減少停機時間，維護和校準成本。它們提供24標準壓力范圍，從真空到30,000 psi（2,000 Bar），多個電氣和過程連接，以及高精度到0.1％FSO（包括線性，滯后和重復性）。 BiT產品系列均提供三種基本型號：

1）采用HART通信協議的4-20 mA輸出，
2）4-20 mA輸出，
3）1-5 VDC輸出，可選定制電壓輸出高達10 VDC。


具有HART協議的BiT系列450和450X提供了除正常過程變量之外的其他信息。它們提供診斷，設備狀態和其他校準功能，包括遠程量程可調性和零點調整。 HART通信協議以數字方式提供所有這些信息，而不會改變現有的4-20 mA接線。數字信號疊加在4-20 mA電流環路上，并由所有主要PLC制造商提供支持，并進行簡單的I / O模塊升級。


除了HART功能外，BiT 450和450X系列還通過薄膜傳感技術提高了精度和穩定性，提供了長期穩定性和高精度。薄膜技術的長期穩定性增加了校準間隔之間的時間，從而降低了維護成本并保持了校準間隔之間的準確性。


“Barksdale已成功設計和供應壓力變送器解決方案超過35年，”Barksdale的副總經理，石油和天然氣總經理Tarun Shivlani說。 “對于我們的新BiT，我們使用了我們廣泛的壓力變送器設計專業知識，并將其與HART協議標準相結合，生產出比同類競爭對手更小的高性能不銹鋼變送器。”


BiT系列450X是防爆型號，提供危險區域防爆保護，符合北美，歐洲和國際標準，具有cULus，ATEX，IECEx和Single Seal認證。防爆外殼采用全焊接不銹鋼制造，符合IP66和IP67標準，符合NEMA 4X標準。 450X系列機型的典型應用包括海上控制面板和其他油氣處理和生產設備。


BiT 450系列適用于OEM重型移動設備測試的非機密區域。該系列包括流行的工業和MS型連接器，便于連接，并獲得cULus批準用于普通地點。

Los Angeles, CA – Barksdale, a leading manufacturer of industrial controls, is pleased to announce the release of its first digital pressure transmitter family with HART communication protocol: Series BiT. Our new BiT, short for Barksdale Intelligent Transmitters, has two product series: Series 450X, with explosion proof rated enclosure, designed for hazardous area applications in Oil & Gas industry; and Series 450, which is designed for high pressure test & measurement and general industrial applications.

BiT, Series 450 and 450X, are part of our new line of high-pressure transmitters designed with advanced electronics and sensing technologies to maintain stability, reduce downtime, maintenance and calibration costs. They offer 24-standard pressure ranges from vacuum to 30,000 psi (2,000 Bar), multiple electrical and process connections, and high accuracy to 0.1% FSO (including Linearity, Hysteresis and Repeatability). Both BiT product series offer three basic models: 1) 4-20 mA output with HART communication protocol, 2) 4-20 mA output, 3) 1-5 VDC output with optional custom voltage output up to 10 VDC.

BiT, Series 450 and 450X, with HART protocol provides additional information beyond the normal process variable. They offer diagnostic, device status and other calibration capabilities, including remote span adjustability and Zero trim. HART communication protocol provides all this information, digitally, with no changes to the existing pair of 4-20 mA wiring. The digital signal is superimposed on the 4-20 mA current-loop and is supported by all major PLC manufacturers with a simple I/O module upgrade.

In addition to HART capabilities, BiT Series 450 & 450X have raised the bar for accuracy and stability with thin-film sensing technology that provides long-term stability and high accuracy. The long-term stability of thin-film technology increases the time between calibration intervals reducing maintenance cost and maintaining accuracy between calibration intervals.

“Barksdale has been successfully designing and supplying pressure transmitter solutions for over 35 years,” said Barksdale's VP, General Manager-Oil & Gas, Tarun Shivlani. “For our new BiT, we used our extensive pressure transmitter design expertise and combined it with the globally-accepted HART Protocol standard to produce a high-performance, stainless-steel transmitter that is smaller than competitors in its class.”

BiT, Series 450X are explosion proof models that provide hazardous area explosion protection to meet North American, European and international standards with cULus, ATEX, IECEx and Single Seal certifications. The explosion proof enclosure is an all-welded stainless-steel and is IP66 & IP67 and NEMA 4X rated. Typical applications for Series 450X models include offshore control panels and other Oil and Gas process and production equipment.
