Procemex pinhole camera housing provides always 100% visibility with a top image quality.
The stainless steel camera housing is designed and constructed specifically for the purpose of accomodating cameras with pinhole zoom lenses.
Web monitoring cameras are kept clean under harsh wet end conditions with the aid of instrument flow. The air is blown through a 5 mm hole in front of the camera housing. As the air flow speeds up when passing the pinhole it forms a strong protection against dirt and prevents water and dirt entering into the housing. The housing has no protection window that could get dirty or wear out. The camera is equipped with a dedicated pinhole zoom lens capable of viewing through the hole.
The benefits of pinhole cleaning are trouble-free operation, low air consumption, 100% continuous visibility and the simplicity of the concept . There are no moving and wearing parts; wipers, electronics or controlling components. Continuous air flow enables pinhole cameras to film undisturbed 100% of the time without washing cycles or wiper movements causing blind times during the cleaning process
Cameras are cooled using instrument air. Temperature insulation inside the camera housing reduces significantly the need for cooling. In some positions warmer than 60°C (140°F) it is necessary to use a Vortex cooler to guarantee a suitable ambient temperature for the camera. In extremely hot positions like in modern impingement dryers reaching 200°-250°C (390°– 480°F) ambient temperatures, it is necessary to use water to cool the cameras.
