Model DGA-410 & DGA-410M Dual-Gamma Ash Analyzer

The Model DGA-410 and DGA-410M Dual-Gamma Ash Analyzers are advanced instruments designed to measure the ash content, heating value, and weight of combustible materials. The DGA-410M adds a density-based moisture correlation module to measure moisture. Initially developed for the coal industry, these analyzers have been adapted for use in processing cement, minerals, and biomass materials. The device features a source and detector assembly mounted across a conveyor belt, allowing for non-contact, non-destructive real-time analysis as the material passes through. The detector is linked to an electronics enclosure, housing an industrial computer which processes the detector signals and displays the measured results to the operator.

The Dual-Gamma Analyzer generates measurements every three seconds, averaging these readings over a 60-second period to produce minute values for ash content, heating value, weight, and in the 410M, moisture. These minute values are made available to plant control systems through direct access to the system database or via analog and digital outputs provided with the system. The data can be used to sort material by quality or blend material to achieve a desired quality.
