Application
HM8443 series side mounted refrigerant level gauges are equipped with proportional voltage output or voltage output TwinSite® sender capsules with ranges of 1-2 volts, 1-6 volts or 0.5 to 4.5 volts output Hall Effect. They interface with various microprocessor based controllers now being used in commercial/supermarket applications for continuous, repeatable measurement of refrigerant levels and rates of loss.

General Information & Features
These gauges feature a 4-bolt brass head with integral mounting pads to accommodate the attachment of an electrical junction box. The junction boxes furnished with these gauges are not watertight and it is recommended that the connections inside boxes be made using waterproof connectors for rooftop and other outdoor service applications.

这些仪表通常配有与几种常用制冷剂和润滑剂兼容的氯丁橡胶垫圈。可能还有其他垫片材料。

配有这些仪表的表盘是磁力驱动的。这意味着可以拆除表盘, 并通过拆除两个 #6-32 螺丝来更换表盘, 而不会干扰四个仪表安装螺栓并释放接收器内容。

原配有直接读取或直接读取加电压输出的仪表上的表盘通常是可互换的。换句话说, 只需卸下两个 #6-32 螺丝, 就可以用0.5 至4.5 伏霍尔效应表盘替换1-2 伏输出拨号。

霍尔效应拨号具有0.5 至4.5 伏输出, 引入了以前不可用的无噪声可靠性和使用寿命。所有直接只读的拨号和直接读取电压输出都适用于室内和室外位置。
