Paper and pulp mills combine high humidity, steam, alkaline white water, and the physical scale of paper machine installations — paper widths can exceed 10 m and machine speeds 2,000 m/min. Sensors must be robust enough to survive continuous water exposure and vibration, while remaining accurate enough to detect web breaks and sheet presence at full machine speed.
Pantron ISM-8000
Pantron ISM-8000 long-range light barriers span the full paper machine width to detect web breaks in wet-end sections, triggering emergency sheet break sequences before the sheet wraps the rolls.
di-soric Distance Sensors
di-soric laser distance sensors measure roll diameter on winder reels during winding, calculating the correct reel change point and controlling winder nip pressure.
EGE Inductive Proximity
EGE inductive sensors monitor flow rates and valve positions in the headbox feed system, providing process control data for basis weight and formation management.
EGE Inductive Proximity
EGE inductive proximity switches confirm that press roll loading actuators have achieved the set nip load position before the paper machine speed is increased through the press section.
Lion Precision Eddy Current
Lion Precision eddy current sensors measure disc refiner plate clearance in TMP and groundwood refiner installations, enabling precise plate gap control at full operating temperature and pressure.
Pantron Fork Light Barriers
Pantron Fork Light Barriers detect belt edge position on wide pulp conveyor belts, triggering belt tracking corrections before belt edge damage occurs at high speeds.
Schmersal Safety
Schmersal safety interlocks protect access to chemical recovery boiler smelt dissolving tanks and other hazardous areas in kraft pulp mills, preventing access when smelt spout doors are open.
