传送器可帮助处理现场测量,更精确地测量明渠流量。 德州奥斯汀2008年1月15日消息,艾默生过程管理公司推出新版流行的Mobrey® MSP900超声波传送器,设计用于明渠流量测量的优化。新MSP900FH是一款预接线遥控温度传感器,是水处理和工业处理上提高明渠流量测量精确性的理想选择。 当用在户外测量时,传统的超声波传送器在太阳直射时,很容易受来自太阳能增加造成的误差影响。Mobrey MSP900FH传送器已将遥控温度传感器直接与传送器相连,经过专门设计克服了这些问题。测量范围恰好是10mmX25mm, 紧凑的传感器可以很容易地安置在适当的背阴位置,位于液体表面与传送器之间。这样,系统保证以声速估算的气温测量才是真实且具代表性的。 传感器通过硬线接入带有两米电缆的传送器中,所以没有额外的电缆或是安装要求,仅有一个控制器的单相连接,以保证最低的安装成本。 艾默生水力行业专家Peter Ward解释说:“这是对普通问题最简洁且具功能性的解决方案。在用户现场, MSP900FH在拓展领域测试中的始终如一的表现都超出传统的设计。“ Mobrey MSP900FH是一款24V直流回路动力装置,具有防水性能,密封级为IP68。既有4-20mA的通信装置,还有内置的HART选项,可单独应用也可作为现场测量、数据控制和收集系统的一部分。 Mobrey MSP传送器是智能化、数字化现场总线的一部分,为PlantWeb®数字工厂架构供以动力,工厂效率改善可达2%,传送更多资产优化、过程自动化和执行管理信息。 [FONT=times] original text [/FONT] [font=times] Emerson’s new Mobrey® ultrasonic level transmitter is optimized for open channel flow measurement [/font] [font=times][Color=#708090]Transmitter helps processing sites measure open channel flow more accurately. AUSTIN, TEXAS (January 15, 2008) – Emerson Process Management is offering a new version of its popular Mobrey® MSP900 ultrasonic level transmitter, optimized for use in open channel flow measurement. The new MSP900FH features a pre-wired remote temperature sensor and is ideal for water and industrial processing sites looking to improve the accuracy of their open channel flow measurements. Used in the open air, conventional ultrasonic level transmitters are prone to suffer from inaccuracies caused by "solar gain" when the sun shines directly on them. The Mobrey MSP900FH transmitter has been designed to overcome this problem by using a remote temperature sensor wired directly into the transmitter. Measuring just 10mm diameter x 25mm length, the compact sensor can easily be located in an appropriately shady spot between the liquid surface and the transmitter. In this way, the system ensures that the air temperature measurement used in the speed of sound calculation is truly representative. The sensor is hard-wired into the transmitter with a two-meter cable, so there is no additional cabling or set up required, and only a single connection to the controller, thus keeping installation costs to a minimum. "We have made this development as a direct response to what our customers were telling us," explains Emerson water industry expert Peter Ward. "It is a neat, functional answer to a common problem. In extended field trials at a customer site MSP900FH consistently out-performed competitive conventional designs." The Mobrey MSP900FH is 24V DC loop powered, supplied in a waterproof housing sealed to IP68. It has both analog 4-20mA communications and digital HART options built-in, and can be used stand-alone, or as part of a site-wide measurement, control and data acquisition system. Mobrey MSP level transmitters are part of the broad range of intelligent, digital field devices that power the PlantWeb® digital plant architecture to improve plant efficiency by 2% and more through delivering asset optimization, process automation, and management execution.
