ABB HPIR Moisture Sensor for Quality Control System

The recently introduced high-performance infrared (HPIR) grade moisture sensor from ABB is designed to offer increased confidence to paper manufacturers about the precision of their moisture measurement process.


The sensor, which is aimed for use with ABB’s QCS800Xa quality control system (QCS), is expected to help papermakers achieve faster changes in paper grades and start ups, besides tighter CD control. Manufacturers will also be able to achieve moisture targets that are nearer to acceptable limits of quality, reduce fiber expenses, and save energy while at the same time adhere to quality specifications of the paper grade.

This sensor has been designed to replace the widely utilized HemiPlus moisture sensor. It can also enhance the stability and performance of both current and emerging ABB QCS.
A number of design breakthroughs have imparted the improved precision of this new sensor, along with a considerable increase in sensor measurement rate and signal to noise ratio. This sensor is now capable of resolving moisture streaks of even 4 mm width. The sensor is also able to offer precision measurements due its 5000-per-second measurement rate, at a time when paper machines are becoming faster and broader.

Simplicity in design has also contributed to new reliability levels for the sensor. HPIR is a moisture sensor that is devoid of continuously movable components and it does not need liquid cooling. Its modular design enables easy module replacement on the field and eliminates factory repairs and the requirement to stock an entire spare sensor.
