Product catalog summary
Overview: The document describes the Biomass Gas Analyzer , designed for simultaneous and continuous monitoring of four gas components: H2S, CH4, CO2, and O2. It is compact, lightweight, and equipped with various optional functions for enhanced usability.
Specifications: The analyzer measures gases using different sensors: single-beam infrared sensors for CH4 and CO2, a galvanic cell sensor for O2, and a constant-potential electrolytic sensor for H2S. It supports a measurement range of 0 to 100 vol% for CH4 and CO2, 0 to 25 vol% for O2, and up to 5000 ppm for H2S.
Features: Key features include automatic calibration, concentration alarms, and RS485 (MODBUS) communication. The device offers a user-friendly LCD display and optional gas concentration alarm outputs. It supports remote input for range switching and automatic calibration cycles ranging from 1 to 99 hours or 1 to 40 days.
Applications: The analyzer is suitable for biogas applications, where biogas is generated from biomass resources such as livestock excrement, sewage sludge, and food waste. The biogas composition typically includes CH4 (50-75 vol%), CO2 (25-50 vol%), and trace amounts of other gases.
Performance: The device ensures high accuracy with repeatability of ±0.5% FS for most gases and ±2.0% FS for H2S. It features a response time of 10 to 30 seconds for most gases, with longer times for higher H2S concentrations.
Operational Conditions: The analyzer operates within a temperature range of 5°C to 40°C and requires a power supply of 100 to 240 V AC. It is designed for use in environments with low dust and pressure conditions.
Maintenance: The sensors have a life expectancy of approximately 1 to 2 years, depending on the gas type. Regular calibration and maintenance are facilitated by the automatic calibration feature.
Connectivity and Outputs: The device supports analog outputs (4 to 20 mA DC or 0 to 1 V DC) and contact outputs for various alerts and status indications. It also allows for remote control and monitoring through digital inputs and RS485 communication.
