ST-3300

Smart RF Moisture Analyser for Industrial Manufacturing

Since many materials used in industrial processes have quality standards relating to moisture, the ST-3300 is a smart, simple and effective solution to help operators manage and control moisture at critical stages of their process. Using radio frequency dielectric measurement (RF) technology, the ST-3300 provides a rapid and complete moisture profile of products at full line speeds — unlike NIR sensors, which measure only the surface, RF technology penetrates the full thickness of the product.

Key Benefits

• Customisable to your operation, with a wide range of configurations to integrate moisture measurement almost anywhere in your process.
• Simple implementation via a powerful configuration software package that manages every sensor in your process from a laptop or PC.
• Ruggedised design, virtually maintenance-free in challenging operating conditions and temperatures up to 540°C (1000°F).

Features

• Signal processing capabilities can be integrated into the transmitter electronics.
• Mounting options available to accommodate diverse process locations.
• Interfaces directly with your preferred HMI (PC, PLC, or optional 305 mm/12 in touch screen display).
• Advanced digital conditioning for improved resolution and stability.
• Optional product temperature measurement capability.

How It Works

As product passes across rollers, the ST-3300 transmits an RF signal from the upper and lower sensor electrodes surrounding the material. The measurement area at the bottom of the sensor antenna reads moisture conditions in the local environment, displayed in real time on a PC, laptop or optional touch screen display, so operators can adjust the process to control moisture as needed.

System Components & Installation

The ST-3300 features a patented RF measurement principle enhanced by all-digital phase lock loop signal conditioning for a radically improved standard of resolution and stability. It’s an open-frame configuration installed between conveying belts or rollers, exiting or entering a kiln or dryer, with antenna lengths from 150 mm to 2440 mm (6 in to 96 in) depending on operating temperature — ideally suited to board materials such as gypsum and plywood.

Applications

The ST-3300 is used across lumber and wood (sawdust, hog fuel, veneer, plywood, biomass, wood pellets), building products (gypsum products, brick, board products), textile mill products (broad-woven and non-woven fabric), and paper products (pulp, paper, paperboard, containers and boxes, converted paper and paperboard products).

Software

The ST-3300 includes a powerful configuration software package that manages every sensor in your process through a laptop, PC or optional touch screen display — with graphic display and data-logging to .xls or .csv, up to 50 stored calibrations for quick setup, and a diagnostics screen to monitor sensor health.
