小号和老号R3D表盘 - LP

小和老R3D表盘

Application
The Rochester Remote Ready Dial, R3D® – LP, is a magnetically-driven, Hall Effect compatible dial. Dials are utilized on stationary applications where direct reading plus an electrical signal to a remote fuel level monitor may be required. Models are available to fit all Rochester Junior, Senior and Snap-Onliquid-level gauges.

罗切斯特的霍尔效果模块设计用于在远程准备拨号镜头中安装在凹槽中。一旦安装, 该模块可以提供与油箱内液体体积成比例的比率电压输出。

General Information & Features
In the area of LP gas measurement, a magnetic drive feature is important because a magnetic drive allows a signal from the float mechanism inside the tank to be transmitted through a solid bulkhead.

R3D®-lp 表盘设计用于允许第二次磁耦合。这是 R3D®-LP 指针磁铁的耦合, 通过密封镜头进入霍尔效果模块。

以前设计的产生电气输出信号的磁力驱动表盘具有使用带雨刮器臂接触的可变电阻器所固有的缺点。霍尔效应传感器的磁连接比依赖可变电阻器件滑动触点的系统更可靠。

霍尔效应是一种没有移动触点的固态技术。它依靠的事实是, 磁铁弯曲电子通过半导体运动的路径。电子的弯曲可以被检测并转换成电信号。

R3D®–P l 和霍尔效应模块可用作现有 LP 储罐仪表的改造, 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。

R3D®-lp 表壳通过超声波焊接密封, 将外壳熔化并融合成一块实心件。这使得天气不稳定, 在极大地延长了机械寿命的同时, 也读出了 "无雾"。该密封件是一种高可靠性、无垫片的设计。

塑料外壳比任何金属包裹的耐磨性都要耐腐蚀, 并且能够承受每种产品的广泛变化。镜头和外壳是一种特殊的紫外线稳定塑料材料。

R3D®–p l 表盘安装在罗切斯特少年或高级仪表上, 带有 #0040-00416 不锈钢表盘螺钉 (6-32 x 3/8 ")。一个广告项目, 以确保耐候性连接从模块到远程显示器是热收缩溶胶, 套筒部分 num ber 0025-00495。
