一款California配有MBD 1000数字显示器和MBS 3000压力传送计的增压泵集分器已经取代了传统的压力仪表，可以节省组装、测试、维护和服务成本。
降低安装时间简化维护
高层楼宇和商业大厦需要一个专业的增压泵系统以保证有充足的水压给所有楼层供水。最近几年里，对这些工厂的控制技术已变得日益成熟和有效。目前已经有许多集分器用于电子传感器提供压力信息，但仍有一部分样式陈旧的传统测量仪表用于压力监视。
用丹佛斯MBD 1000即插即用数字显示器替代现有的传统测量仪表，Cal Hydro已经降低了组装和测试时间，使得系统更容易操作和维护。
普通类型的压力测量仪相对比较便宜些，但是缺少从一个到另一个的精确性和可重复性。测量仪表还需要专业的水管装置和经常替换。仪表一旦安装就要进行校准。如果数字不匹配，错误将必须说明原因，列入日常维护，避免不必要的时间损耗和复杂性及多余的成本。
丹佛斯解决方案用MBD 1000替代了测量仪表和它伴随的配管，直接与MBS3000传送器相连接，可以节省相当多的安装时间和成本。自从显示器由相同的直流电压供电开始，就不再需要额外的线。MBD1000显示器可被数字化的调整与控制器读数精确匹配。由于显示器的输出由传送器锁定，精确性则由操作压力控制。
MBD 1000其它的优势就是其可编程性和多功能选择性安装。简单的编程就能允许仪表示数在各种显示器单元上显示，如PSI、bar和KPA。简单的可调整的安装允许MBD 1000来回转动，方便观察。
购买丹佛斯传送器和显示器解决方案仅比购买竞争者配有传统仪表的传送器贵一点，由于简化了组装，实际安装成本比先前要少许多，更不用说进一步节省的服务费用和维护成本。

A California booster pump integrator has replaced conventional pressure gauges with the MBD 1000 digital display unit and MBS 3000 pressure transmitters, saving costs in assembly, testing, maintenance and service.
Reduced build time and easier maintenance
High-rise apartments and commercial buildings require dedicated booster pump systems to ensure adequate water pressure on all floors. In recent years, controls for these plants have become increasingly sophisticated and efficient. While most integrators now use electronic sensors to supply pressure information, most still employ old-style conventional gauges for visual monitoring of pressure.
By replacing the existing traditional gauges with Danfoss MBD 1000 plug-in digital display units and MBS 3000 pressure transmitters, Cal Hydro has reduced assembly and test time, and made its systems easier to operate and maintain.
Ordinary dial-type pressure gauges are relatively inexpensive, but lack accuracy and repeatability of measurement from one to another. Gauges also require dedicated plumbing and frequent replacement. Once installed the gauge must be calibrated. If the numbers don’t match, the error will have to be accounted for in future field service or routine maintenance, adding needless time, complexity and cost.
The Danfoss solution replaces the gauge and its associated plumbing with the MBD 1000 coupled directly to the MBS 3000 transmitter, saving considerable build time and expense. Since the display unit is powered by the same DC voltage that feeds the transmitter, no additional wiring is required. The MBD 1000 display can be digitally adjusted to exactly match the controller reading. Because the display unit’s output is locked to the transmitter, accuracy is ensured across the full operating pressure range.
Additional advantages of the MBD 1000 are its programmability and mounting adaptability. The simple programming allows readings to be displayed in various units, such as PSI, bar, or kPA. The easily adjustable mounting allows the MBD 1000 to be pivoted for easy viewing.
The Danfoss transmitter and display “kit” solution cost California Hydronics little more to purchase than the combination of a competitor’s transmitter with a conventional gauge. Thanks to the simplified assembly, the actual installed cost is considerably less in comparison, not to mention the future service/maintenance cost savings.
