Control Boxes

Control boxes

Control boxes are an integral part of every Xoptix installation and play a critical role in ensuring reliable operation of the complete online particle size measurement system. While the particle sizer is the most visible component, the control infrastructure behind it enables automated sampling, sample transport, measurement, cleaning, and communication with the plant control system.

The electrical control section manages all active components within the installation, including motors, pumps, valves, actuators, sensors, and cleaning devices. It ensures coordinated operation of the complete system and executes the sequences required for startup, shutdown, cleaning cycles, and routine process operation.

A dedicated control board X8 provides communication between the particle sizer, local operator interfaces, and supervisory computers. It collects measurement data, monitors system status, manages alarms, and ensures stable data transfer between all components of the installation.

The automation interface allows seamless integration with plant control systems such as PLCs, DCS, or APC platforms. Both digital and analogue signals can be exchanged, enabling the system to receive operating commands while transmitting particle size data, status signals, alarms, and diagnostic information. Dedicated I/O modules are used to control valves, motors, sensors, and other field devices.

For pneumatic systems, Xoptix also provides dedicated pneumatic control boxes containing pressure gauges, flowmeters, regulators, manifolds, solenoid valves, filters, and air distribution components. These assemblies ensure stable operation of sampling systems, conveying circuits, cleaning functions, and measurement cells while simplifying maintenance and troubleshooting.

Control boxes are designed and manufactured using proven standard design blocks developed through many years of industrial experience. This modular approach improves reliability, simplifies engineering, reduces commissioning time, and ensures consistency across different installations.

The final configuration can be adapted according to the complexity of the system and the specific requirements of each customer site. Small standalone installations may require only basic control functionality, while large multi-sampler systems can incorporate extensive automation, diagnostics, safety functions, and advanced process integration.

Different enclosure sizes are available to accommodate various project requirements. Components may be integrated into a single cabinet or distributed across several electrical and pneumatic enclosures depending on available space, maintenance access, environmental conditions, and installation layout.

Control boxes can be mounted in several ways depending on site conditions. Common installation methods include wall mounting, direct attachment to process structures, suspended mounting arrangements, welded support arms, or installation on dedicated Xoptix aluminium T-slot frames. This flexibility allows the control infrastructure to be positioned optimally while maintaining accessibility for operation and maintenance.
