Papcel, a Czech Republic-based papermaking machinery manufacturer, is employing Exergen’s noncontract infrared sensors in its Softcalender paper machine to ensure optimal operational efficiency and paper quality.

Exergen’s IRt/c.5 sensors maintain the temperature required to precisely control the paper drying process. Employed at multiple points in the operation to measure the temperature of the swimming roll that is rotating up to 400 rpms, the sensors signal air jets to open or close in order to cool the drum and keep it at 194°F (90°C).

Precise temperature measurement is critical in print production because overheating can damage the drum, sensors and other equipment, potentially costing thousands of dollars. In addition, if substrates measure below or above very specific temperature ranges, the end quality can be degraded.
