THERMOX - Model CMFA-P2000 -Portable Premix Gas/Flue Gas Analyzer

Using a highly reactive bare platinum zirconium oxide cell, the CMFA-P2000 is capable of measuring excess oxygen (O₂) in post-combustion flue gas or excess O₂ to excess fuel in premixed combustion samples feeding forehearth zones.

The CMFA-P2000 is designed specifically to meet the dual furnace combustion monitoring requirements of the glass and glass fiber manufacturing industry. It is often used in forehearths, melting tanks, flame treating and furnace atmosphere control.

EASY CONTROL DURING PROCESS ANALYSIS
The portable, two-piece analysis and control arrangement allows system separation. This allows users to view the readout control while making remote adjustments of premix and combustion air valves.

OPTIONAL AIR COMPRESSOR
The CMFA-P2000 is available with an optional air compressor for driving the integral air operated aspirator. This allows sampling of low-flow premix gases and pulling flue gas samples under draft conditions.

ACCURACY EVEN IN IMPRACTICAL APPLICATIONS
In premix mode, the CMFA-P2000 measures the air/fuel ratio in open-flame applications, where flue gas measurements are impractical. It delivers greater accuracy than directly measuring O₂ or combustibles in the premix gas and works in both excess fuel and excess air environments.

The CMFA-P2000 is our portable premix and flue gas analyzer designed specifically for glass container manufacturing plants.

• Two analyzers in one package – for flue gas O₂ and premix gases
• Built-in compressor for sample analysis
• Works in excess fuel or excess air environments
• More accurate than direct measurement in premix gas

Enclosure: Both the sensor and control unit are housed in a luggage style, aluminum carrying case

Display: Four-line x 20-character vacuum fluorescent display. Displays combinations of excess oxygen, excess fuel, combined excess oxygen to excess fuel, fuels/oxides, oxides to fuels, combustibles, time and date, cell temperature, user programmable text, thermocouple mV, or cell mV. Password protection and context sensitive help are also provided.

Diagnostics: System test for A/D, RAM, EEPROM and keypad. Display line 4 reserved for full text error and diagnostic messages. Twenty-entry event log.

Analog Output: Isolated, linear current output, fully scalable. Select excess oxygen, excess fuel, combined excess oxygen to excess fuel range, combustibles, fuels/ oxides, oxides/fuels, cell temperature, thermocouple mV and cell mV. Hold or track during calibration and select degree of damping. Maximum load 1200 ohms.

Calibration: Calibrate or verify calibration. Store last calibration and verification data.

Built-in Compressor: Draws gas from up to 6 inches of water vacuum.
