ABB’s patented High-Performance Infrared Reflection (HPIR-R) moisture sensor…

ABB has released its High-Performance Infrared-Reflection (HPIR-R) moisture sensor, which provides the fastest, most precise moisture monitoring available on the market today. Taking up to 5,000 measurements per second, the sensor delivers precise, high-resolution measurement that enables mills to increase throughput while reducing operating costs.

This advanced, patented technology will help pulp, paper and board producers to always know the precise moisture levels, giving them confidence to raise moisture targets and improve their CD profiles, enhancing end product quality with fewer rejects as a result.

Being able to measure and control the moisture levels as the sheet moves through the paper machine is critical to reducing energy requirements. This leads to optimized drying, decreased steam usage, significant energy savings in dryer sections and reduced carbon emissions. In fact, changing the steam pressure to create a moisture change of just 1% can equate to $400,000 in energy savings.

The small spot of infrared energy used in the sensor provides excellent streak resolution and accurate edge-to-edge sheet measurement, even in the most difficult environments. Measurement while scanning is continuous, with no beam chopping or filter wheels ensuring optimum signal-to-noise ratio and maximum measurement rate.

ABB’s new HPIR-R moisture measurement, which also has a built-in sheet temperature sensor, is designed to be fully air-cooled and field repairable. That, coupled with its insensitivity to dust and disturbances enables high uptime and lower total cost of ownership than similar solutions.
