GreCon ABC 7

• Avoid production shutdowns
• Detection of blockages of the rotary valve
• Eliminates unnecessary environmental pollution and emissions

The ABC 7 control console is the core of the cyclone blockage detector. It collects the measuring signals of the individual monitoring zones of different cyclones. When a material blockage occurs in one of the connected cyclones, the operators are informed immediately, and the conveyor fans in the corresponding areas shut down via voltage-free relay outputs.
Equipped with modern plug-in card system, the modular control console can be configured for monitoring of up to 12 cyclones. Special infrared transmitters are used to generate a stable infrared signal.

Receivers using a highly sensitive electronics detect the infrared signal. The combination of both components guarantees a perfect operation, even for big cyclones with long distances between transmitter and receiver. Two types of transmitters and receivers are available for different applications.

For process temperatures below 60 °C, the transmitters and receivers are installed directly on the cyclone wall.
In areas of high process temperatures (> 60 to 360 °C), such as material drying processes, the transmitters and receivers are connected with the cyclone via fibre optic cables. Thus, the electronics is separated from the high working temperatures in the installation position. Additional cooling measures are not necessary.

The transmitters and receivers as well as the fibre optic cables are mounted on the cyclone wall by means of patented mounting adapters, which are constructed in such a way that they can be flush-mounted and hardly impair the material flow.
