美国 Babbitt LS7000/2 双报警点射频开关
 

LS 7 0 0 0/2双点RF电平开关

RF电平的LS7000 / 2的双点开关采用专有的射频（RF）平衡阻抗桥。 它是专门设计来自动填充或清空坦克，船只或油底壳。 的高，低设定点是可调的整个长度的探针。 本机是专为使用均质液体。

的双点液位开关使用一个单一的继电器和用于自动操作的一个板上的锁存电路。 无需外部锁存继电器或接触需要简单地串联泵起动器或电磁阀继电器输出接线。

要自动填充容器，选择“自动填充”上的电子设备，继电器通电时，材料下方的“低”设定点。 该泵将开启，并继续运行，直到水位达到设定点“高”，然后关闭。 对于“自动空”，继电器的动作是相反的。

对于导电性材料，一个海拉尔涂布探针是必需的。

所有指标是必要的校准板，使所有需要校准的LS7000 / 2是小螺丝刀。 模块化电子设备进行故障排除和修复一个单元。 备份整个单元通过我们两年保修。

探头采用316不锈钢棒的固体，是由聚四氟乙烯绝缘体。 à哈拉尔探头涂层需要在所有的导电液体。 密封件均采用氟橡胶“O”形圈。 所有的电子设备都装在铸铝防爆外壳。

L S 7 0 0 0 / 2   Dual Point RF Level Switch

The LS7000/2 dual-point RF level switch uses the proprietary radio frequency (RF) balanced impedence bridge. It is specifically designed to automatically fill or empty a tank, vessel or sump. The high and low set points are adjustable over the entire length of the probe. This unit is designed for use in homogeneous liquids.

The dual-point level switch uses a single relay and an on-board latching circuit for automatic operation. No external latching relays or holding contacts are required Simply wire the relay output in series with a pump starter or solenoid valve.

To automatically fill a vessel, select "AUTO-FILL" on the electronics, and the relay will energize when the material is below the "LOW" set point. The pump will turn on and continue to run until the level reaches the "HIGH" set point, then shut off. For "AUTO-EMPTY", the relay action is reversed.

For electrically conductive materials, a Halar coated probe is required.

All the necessary calibration indicators are on-board so all you need to calibrate the LS7000/2 is a small screwdriver. The modular electronics make trouble shooting and repair a snap. The entire unit is backed by our two year warranty.

The probe is made of solid 316 stainless steel rod, and the insulator is made of Teflon. A Halar coating on the probe is required in all electrically conductive liquids. The seals are made with Viton "O" rings. All the electronics are housed in a cast aluminum explosion-proof enclosure.
