Inline Near-Infrared Moisture Meter Custom Spectral Solution - AMT-SFY-HW

I. Product Introduction of Inline Near-Infrared Moisture Meter Custom Spectral Solution

The near-infrared online moisture meter is aNon-contact, non-destructive, continuous real-time moisture content detection equipment, based on the principle of near-infrared spectral absorption-diffuse reflectance of water molecules. The probe is installed above belt conveyors, chutes, or dryer discharge outlets. No sampling or material contact is required, with millisecond-level real-time moisture reading. It can directly interface with PLC and DCS control systems to achieve closed-loop automatic control of drying and humidification processes, eliminating the lag of offline laboratory analysis, stabilizing product moisture content, and reducing drying energy consumption. It is a dedicated instrument for intelligent moisture management in industrial production lines.

The entire equipment consists ofDetection probe + control host + signal cableComposed of three parts; supports multi-material curve storage, temperature and dust compensation, adapting to harsh workshop conditions such as dust, high temperature, and high humidity, with 24-hour continuous operation.

Core principle: Water molecules absorb specific bands of near-infrared light. The instrument emits a light source to irradiate the material surface, receives reflected light signals, and calculates the material moisture content value through built-in algorithm models. Detection processNo damage to materials, no consumables.

II. Main Functions of Inline Near-Infrared Moisture Meter Custom Spectral Solution

1. Real-time continuous detection: Continuous measurement of dynamic materials on the production line, real-time display of moisture content, fast response speed, no detection delay
2. Non-contact non-destructive measurement: Probe does not touch material, no sample loss, no material contamination
3. Multi-material curve storage: Built-in multiple calibration curves, one-click switching between different materials, one machine for multiple uses
4. Intelligent compensation algorithm: Temperature compensation, dust compensation, material color/thickness compensation, reducing environmental interference, stable measurement
5. Real-time data output: 4-20mA analog, RS485-Modbus digital signal, interfacing with PLC, industrial control screens, and host computer systems. Can be linked to dryers for automatic adjustment of drying parameters, enabling closed-loop control of production line moisture.
6. Data storage and traceability: Historical moisture data saved, report export, production quality records traceable
7. Over-limit alarm: Sound and light alarm when moisture is above/below the set threshold, timely warning of non-conforming materials
8. Touch operation: Host color touch screen, parameter settings, curve calibration, and real-time data viewing are simple and convenient
9. Remote monitoring(Optional): Supports IoT cloud platform, remote viewing of production line moisture data via computer or mobile phone
10. No frequent maintenance required: Probe window comes with purge interface (optional), reducing dust adhesion and cleaning frequency
