NIR-7000

Industrial-Grade Continuous Online Moisture Monitoring

The NIR-7000 is a continuous in-line near-infrared (NIR) analyser that delivers reliable, non-contact moisture measurements directly in your process environment for real-time monitoring and control of almost any production line. As the next-generation replacement for the widely used Sensortech NIR-6000, the NIR-7000 features an updated optical platform built for high-throughput industrial applications — including wood, building materials, pulp & paper, minerals, textiles and chemicals — where moisture content directly impacts product quality.

Capturing measurements every four milliseconds, the NIR-7000 automatically adjusts your process to hit moisture targets, cut energy costs and protect your bottom line.

Key Benefits

• High Accuracy: Measures moisture on many product types to within ±0.10%.
• Ruggedised Design: Housed in a powder-coated sheet metal IP65 enclosure built for years of trouble-free operation on the plant floor.
• Simple Implementation: Ships pre-calibrated from KPM’s extensive database, or custom-built to your specific application.

Features

• Improved serviceability, modular architecture and user-friendly software — a significant upgrade over the previous-generation NIR-6000.
• Collects real-time moisture measurements in-process for closed-loop control.
• Pre-programmed algorithms and calibrations, or custom-built to your specification using NIR technology.
• Operates from -20°C (with heating option) up to 85°C (with cooling option).
• Thermal-cooled detector included as standard.
• Flexible top or rear mounting to suit belt conveyors, augers, screw conveyors or sight-glass installations.

How It Works

A halogen light source shines through a rotating filter wheel spinning at 2,000 RPM, isolating the specific NIR wavelengths relevant to moisture. The reflected light is focused onto a cooled sulfide detector, and the on-board smart circuit board compares the signal to an internal reference beam, converting it into a precise moisture percentage — continuously, in real time.

Applications

The NIR-7000 can be delivered pre-calibrated for a wide range of products conveyed on a belt, through an auger, or viewed through a sight-glass window in a bin or chute, including:

• Building products: cement, brick, lime, panelboard
• Chemicals: plastic pellets, industrial organic chemical powders
• Lumber & wood: sawdust, hog fuel, veneer, plywood, biomass, wood pellets
• Mining & minerals: iron ore, coal, copper ore, lead & zinc ore, bauxite, boric acid, ceramic powder, clay, crumb rubber, fertilisers, fly ash, foundry sand, industrial sand, silica sand, frac sand, soda ash
• Paper products: pulp, paper, paperboard, containers, converted paper products
• Textile mill products: broad-woven and non-woven fabric

System Components & Warranty

Every NIR-7000 ships with a powder-coated sheet metal IP65 housing, advanced digital noise filtering hardware, pre-programmed algorithms and calibrations, specialised NIR filtering to suit your application, SensorVu management software, and power and connection cables. Backed by a two-year factory warranty on parts and labour, with a three-year warranty on the lamp.
