Online near-infrared moisture detector - near-infrared online moisture meter manufacturer, free sample testing - online near-infrared moisture detector

1. Product introduction of online near-infrared moisture detector - near-infrared online moisture meter manufacturer

The near-infrared online moisture meter is aNon-contact, non-destructive real-time continuous detectionAn industrial online moisture monitoring device. The equipment relies on near-infrared spectral absorption principles, requires no sampling, does not touch materials, and can be installed above conveyor belts, assembly lines, and roll material production lines to continuously detect moisture content in granular, powder, block, sheet, and roll materials.

The instrument outputs moisture values in real time and can interface with production line control systems for closed-loop automatic regulation. It eliminates manual sampling and laboratory testing processes, solves detection lag issues, stabilizes product quality, reduces defect rates, and lowers drying energy consumption and material loss. The whole machine adopts a split design, with the controller and detection probe separated. One host can be paired with multiple probes to complete multi-point moisture monitoring on the production line.

2. Core functions of online near-infrared moisture detector - near-infrared online moisture meter manufacturer

1. Real-time continuous detection: 24-hour uninterrupted online monitoring of material moisture content with fast data refresh rate.
2. Non-contact non-destructive measurement: The probe does not contact the material, no wear, no pollution, and does not damage the measured material.
3. Online closed-loop control: Moisture signals can be output as 4-20mA/RS485 signals, interfacing with PLC to automatically adjust drying and batching processes.
4. Multi-point detection expansion: A single controller can connect to multiple probes externally, enabling multi-point moisture monitoring on one production line.
5. Data storage and query: Automatically records historical moisture data, supports data export, facilitating production traceability.
6. Abnormal alarm function: When moisture exceeds upper or lower threshold limits, audible and visual alarm alerts operators for timely intervention.
7. Anti-interference compensation: Built-in temperature, material thickness, and dust compensation algorithms to reduce measurement errors caused by environmental fluctuations.
8. Convenient calibration function: Supports on-site calibration, can establish exclusive models based on material sample curves.
