The QN-100 delivers continuous, non-contact near-infrared moisture measurement for bulk solids, powders, and granular materials — giving you accurate, real-time data directly on the production line without interrupting the process.
The QN-100 combines high-accuracy NIR optics with a practical, engineer-friendly design. From the integrated touchscreen HMI to the auto-balance optical setup routine, every aspect is built to make installation, calibration, and daily operation as straightforward as possible — without compromising on measurement performance.
The QN-100 uses near-infrared light to measure moisture content without touching the product. No moving parts in contact with the process means no wear, no contamination risk, and no process interruption.
The sensor delivers a continuously updated moisture reading with a configurable damping filter for stable output. Three 4–20 mA analogue outputs feed directly into your control system for closed-loop drying or mixing control.
A built-in colour touchscreen displays live moisture readings, a 60-minute scrolling trend chart, and full calibration and system configuration — all on the sensor itself, no separate panel required.
Supports Profinet, Profibus DP, EtherNet/IP, Modbus TCP, and EtherCAT — making integration with virtually any industrial PLC or DCS straightforward. Protocol is specified at the time of order.
In addition to moisture, the QN-100 can be configured to simultaneously measure up to two additional components — including oil content, coat weight, or basis weight — using the same NIR optical system.
The IP65-rated sensor housing is suited to dusty, humid, and washdown environments. The optical window is manufactured from robust sapphire or borosilicate glass for long service life.
The QN-100 is installed across a broad range of manufacturing sectors wherever accurate, continuous moisture measurement of bulk solids or powders is critical to product quality and process efficiency.
