Overview
The Siemens 7MB1122-2HA13-1BA1 Ultramat 21 P is a continuous, extractive gas analyzer engineered for precise measurement of gas components in industrial processes. Designed with Siemens’ reputation for process analytics reliability, this unit measures infrared-absorbing gases with high accuracy and stability, making it suitable for applications requiring real-time monitoring and feedback control in automation systems.
Key Features
- Continuous extractive gas analysis for IR-absorbing components
- 120V 60Hz power supply for North American industrial installations
- Ultramat 21 P platform with proven measurement stability and repeatability
- Calibration support for zero-point and full-scale accuracy maintenance
- Integrated sample gas handling and measurement chamber
- Front-mounted membrane keyboard and control interface
Technical Specifications
The analyzer operates in extractive mode, drawing sample gas into the measurement chamber where infrared detection identifies gas components. The unit includes internal gas path management, condensation trap protection, and analog output signals compatible with industrial control systems and PLCs. Operating temperature range and response characteristics are optimized for continuous industrial process monitoring.
Typical Applications
- Industrial combustion control and emissions monitoring
- Chemical and petrochemical process measurement
- Power generation plant stack gas analysis
- Environmental and compliance monitoring
- Biogas and waste treatment facility analysis
- Integration with SCADA, HMI, and automation control systems
Compatibility & Replacements
The Siemens 7MB1122-2HA13-1BA1 integrates with standard industrial automation platforms including Siemens SIMATIC S7 PLC systems, as well as third-party controllers accepting 4–20 mA analog signals. Modern Siemens Ultramat gas analyzer models (such as the ULTRAMAT 23) may serve as forward replacements in new installations, though this unit remains supported for legacy process applications. Verify gas sensor specifications and analog output compatibility with your control system before substitution.
