L&W DS Moisture Sensors

Precision moisture measurement for demanding paper, board, and corrugated applications

L&W DS Moisture Sensor is a high-performance OEM moisture sensor built for applications where accuracy, stability, and integration flexibility matter. Based on advanced microwave technology, it delivers reliable non-contact moisture measurements across a wide range of paper, board, and corrugated products.

Designed for OEMs, machine builders, and system integrators, the new generation brings the measuring range of previous sensor models into one configurable unit. The result is a versatile sensor platform that helps simplify integration and supports consistent performance across demanding applications.

Why choose L&W DS Moisture Sensor

When moisture control is critical, L&W DS Moisture Sensor gives you confidence where conventional methods can fall short. Its microwave-based measurement is not affected by sheet color, ink residues, caliper, surface structure, moisture stratification, pH, salt content, or common fillers such as china clay and titanium dioxide.

That means dependable moisture readings in coated, recycled, multi-ply, and other challenging grades even where process conditions vary.
