In the pulp and paper industry, gamma transmission is used to determine material properties without touching the web. The technique is insensitive to surface temperature, steam and mechanical vibration — conditions that knock out optical or capacitive sensors.
Typical measurement points
- After the press section: basis weight and moisture for entry control into drying
- After the dryer section: quality classification and closed-loop control to PMS
- After coating: control of applied coat weight
Why gamma
- Non-contact — no wear, no web break on stop
- No burn-through risk — high linearity over a wide weight range
- Operational reliability — NT14 is built for 24/7 in hot, humid environments
