ProClean Camera technology keeps cameras clean

Keeping cameras clean in harsh environments is vital for detecting defects. Procemex has been gathering experience about various cleaning methods for over 20 years. It has been our mission to perfect the pinhole camera technology and image quality.  An important milestone on this road is the new in 2020 introduced unique Procemex ProClean Pinhole technology capable to cover all camera resolutions up to 12 MPix with superior light sensitivity and imaging clarity. This is Procemex Crystal ProClean Pinhole Camera.

As most of the cameras are located in the forming and press section, it is clear that keeping cameras and lights clean in a harsh environment is important. This is also a foundation for coming image analysis and AI applications.

Lights are typically kept clean by applying a thin water layer on top of the protection window. The cleaning water also takes care of light cooling.

Fed up with Cleaning Cameras?

The inability to keep web break cameras clean is an everyday reality practically at all pulp and paper mills. Dirt in protection window make images dark and fuzzy.

Pinhole cameras have been used by so far only in most difficult environment, such as paper machine wet end locations. The reason for not using them in every position, has been lower image quality than with the cameras equipped with standard lens and protection window.

This is now changed. The traditional pinhole camera bottlenecks such as:  

• Low resolution                                   
• Low pinhole light sensitivity resulting to lower shutter speeds and in capability to stop fast moving paper web and blurry images
• Pinhole images being sharp in the middle and dark and fuzzy in edge areas   

are not relevant any more!
