Bulk Material Analyzers & Process Controls

ETI designs, manufactures, installs, and services online bulk material analyzers and process control equipment. ETI online analyzers are used in the coal, cement, minerals, and wood/biomass fuel industries to optimize production and to ensure consistent quality in the end product.







Products

Our analyzer product line ranges from PGNAA units providing full elemental analysis to dual-gamma instruments measuring ash, moisture, heating value, and weight/density, as well as single-gamma analyzers measuring weight/density. These online analyzers provide real-time information for plant operators and plant control systems allowing them to make process control decisions immediately based on material measurements.

Additionally, ETI designs and manufactures high speed sort gates and custom sorting/blending equipment. These devices can be directly controlled by an analyzer or by plant control systems to sort and blend materials based on analysis data.

Ashmeter

Dual-Gamma Ash Analyzer

The Model DGA-410 Dual-Gamma Ash Analyzer (Ashmeter) is a registered nuclear gauging device for measuring ash content and weight of bulk materials.

Process Control Analyzer

Process Analyzer

The Model 600 Process Analyzer is a registered microwave/nuclear gauging device for measuring ash, weight, and moisture content of bulk materials.

Density Meter

Density Meter

The Model 500 Density Meter is a registered nuclear gauging device for measuring weight of bulk materials.



FSEA

Full Stream Elemental Analyzer

The ETI Model FSEA Elemental Analyzer combines a Prompt Gamma Neutron Activation Analyzer (PGNAA) and a Density/Ash/Moisture gauge for measuring the full elemental and moisture percentages of various materials including coal, cement products, minerals, and wood products as they are transported on a conveyor.

Sort Gate

High Speed Sort Gate

The Model HSG1 High Speed Sort Gate is a rugged gate assembly for separating materials based on quality. The gate works in conjunction with ETI's Dual-Gamma Analyzer or Process Control Analyzer, and is automatically controlled based on the analyzer measurements taken vs. the set-points controlled by the operator. Manual controls are also supplied.

BTU Meter

BTU Meter

The Model 510 BTU Meter is a registered nuclear gauging device for measuring ash, moisture, heating value, and weight of coal as it travels through a boiler feeder pipe.

Does flow rate affect analysis?

No.

Flow rate has no effect on analysis.

How often must an analyzer be recalibrated?

Rarely, if ever

ETI analyzers are calibrated after installation using samples made from the materials used in the existing process. Laboratory analysis is performed on the samples and a comparison is done with the analyzer results. Analyzer results are then adjusted to match the laboratory analysis...more...
