ZKM Oxygen Gas Analyzers

Product catalog summary

Overview: The document outlines the specifications and applications for Fuji Electric's Zirconia Oxygen Gas Analyzers, specifically the ZFK8 detector and ZKM-2 converter. These analyzers are designed for direct insertion, eliminating the need for gas sampling devices, and are used in industries for combustion control and energy savings.

Key Features:

Modular detector design for easy replacement.
High-speed response time of 4 to 7 seconds.
Explosion-proof case with IP66 and IP67 ratings.
Optional HART communication.
Environmentally friendly, reducing emissions like CO2, SOx, and NOx.

Safety Features:

Automatic power cut-off if thermocouple breaks.
Emergency power cut-off via external input.
Key lock function to prevent errors.

Applications:

Used in industries like steel, power, and petrochemicals.
Applicable in combustion facilities such as incinerators and boilers.

Technical Specifications:

Measuring range: 0-2 to 50 vol% O2.
Repeatability: ±0.5% FS or less.
Response time: 4 to 7 seconds.
Analog output: 4 to 20mA DC or 0 to 1V DC.
Power supply: 100 to 120V AC or 200 to 240V AC.

Construction and Materials:

Flow guide tubes in various materials and lengths, including anti-corrosive options.
Explosion-proof types for hazardous environments.

Optional Features:

Combustion efficiency display.
Auto calibration and blowdown functions.

Installation and Configuration:

Settings adjustable from the front panel without opening the cover.
Various mounting options, including panel and pipe mounting.

Ejector System Overview: The document also provides specifications and connection details for the ZTA ejector system by Fuji Electric, including diagrams for physical layout and electrical connections.

Outline Diagram: Illustrates dimensions and layout of the ejector system, including components like air inlets and outlets, cable gland, and detector, with measurements in millimeters.

External Connection Diagram: Details electrical connections for the ejector system, including O2 sensor input, heater power output, analog output options, and contact outputs for fault, blow, alarm, and maintenance. Specifies power supply input requirements and grounding notes.

Key Specifications:

O2 sensor input and thermocouple input type R specified, though thermocouple not supplied.
Contact outputs rated at 250V AC/3A or 30V DC/3A.
Optional HART communication using a 4-20 mA analog output.
Optional RS485 communication.

Important Notes:

Heater power supply shared with converter power supply.
Cable shield must be grounded in the main body.
