Gladiator vibration level switch

The level sensing arrangement used in the Gladiator vibration smart switch is suitable for a wide range of liquids and solids, including slurries and pelletised materials.

The sensing 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 many situations requiring level detection, including pump control, high- or low-level alarms and detection of an interface between two different materials. Typical industrial uses include pharmaceuticals, food and beverage, mining, water and wastewater treatment, chemical processing and refining.

A remote amplifier option is available so that 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.

There are a number of smart communications options, including GosHawk, DeviceNet, Modbus, HART and Profibus DP. There is also a remote GSM connection option. Any authorised user with a standard modem and GosHawk software can dial in and then calibrate, test or check on the performance of the unit.
