Vibration switch

Hawk has released the Gladiator vibration switch series, a heavy-duty point level device.

The level sensing arrangement is suitable for a wide range of liquids and solids, including slurries and pelletised materials. The element includes two prongs or vanes.

When the prongs on the fork are free to vibrate they are driven to their resonant frequency by piezo ceramic elements.

As the level of the material to be sensed rises, the material blocks the movement of the fork. The electronics in the unit sense this change and produce an output, which can be used for indication or control.

This type of switch is suitable for situations requiring level detection, including pump control, high or low-level alarms and detection of an interface between two different materials.

A remote amplifier option is available. The probe can be separated from the amplifier by up to 500 m. A high-temperature extension allows the unit to handle process temperatures up to 150°C. Heavy-duty construction ensures years of trouble-free operation.
