美磁4"和8"R3D刻度盘 - LP型
Rochester Remote Ready (R3D) Dial for LP Applications
Application
The Magnetoresistive Magnetel® Dial is a magnetically-driven, voltage output sender. These dials are utilized on applications where direct reading plus anelectrical signal to a remote fuel level monitor are required. Models are available to fit Rochester 4” & 8” Magnetel® and Taylor 8” Master liquid-level gauges.
General Information & Features
In the area of LP gas measurement, a magnetic drive feature is important because the fluid is stored under pressure. A magnetic drive allows a signal from the float mechanism inside the tank to be transmitted through a solid, non-magnetic bulkhead without the necessity of dynamic seals or pressure-type conductors.
以前设计的用于产生电气输出信号的磁力驱动表盘液位测量仪的缺点在于使用带有雨刮器臂接触的可变电阻器。有必要对这些液化石油气液位计进行更可靠和更简化的设计, 以提供与容器中液位有关的电气输出。
磁阻是一种固态技术, 没有移动触点。磁阻是材料在施加外部磁场时改变电阻值的特性。微芯片技术将电阻变化转换为可用的电压信号。
MR Magnetel®拨号的优点是, 它可以作为现有船只的改装, 以提供可用于远程监测储罐液位的电气输出。通过对储罐液位的远程监测, LP 气体的分销商将能够更有效地规划向各种消费者的交货。

WARNING! This sensor is not to be used as the primary means of determining high or low fuel condition. It must not be used in the absence of redundant systems in critical applications where there may be significant safety risk or financial exposure in the event of fuel overfill or fuel exhaustion condition. This sensor is not to be used for tank filling.
WARNING! For LP-Gas and other flammable product service applications, connect only to circuits and power sources classified and labeled as Intrinsically Safe for Class 1, Division 1, Group C and D hazardous locations. The connection of non-intrinsically safe power could cause fire or explosion of flammable vapor which may be present.
