Product Details

Mobrey Level Switch

The Mobrey vibrating rod level switch is the perfect solution for single-point level switching in free-flowing solids across a wide density range, from fine powders to grains. A single rod design provides the solution to tuning forks which may become blocked or bridged. The vibration rod is energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics which initiate the switching of the output relay after a built-in programmable time delay.

Supplied with:
User manual, 2 – 3-pole terminal blocks, 1in sealing, 2 – Pg 16 cable glands.

How do you carry out an installation?
Requiring only a 1in BSP/NPT socket, either on the top or in the sidewall of the silo, the unit is easy to install and simple to the commission.
Prior to installation, it is advised to check the switching function for proper adjustment on a sample quantity of material. The unit may not work with mediums within specified density range but having a very large size of granules or extremely little friction.

Handle device with great care, especially the sensing probe. Any impact on the sensing probe can ruin its resonance system.
A protective shield should be installed if the probe is exposed to falling material or an excessive mechanical load.
