Overview
The Siemens ULTRAMAT 23 gas analyzer (model 7MB2335-1CR00-5AA1) is a bench-top or rack-mounted continuous gas analyzer designed for industrial process monitoring and combustion control applications. This unit employs infrared (NDIR) detection technology for precise measurement of CO, Nâ‚‚O, CHâ‚„, and other infrared-sensitive gases, with the option to integrate electrochemical sensors for Oâ‚‚ and Hâ‚‚S measurement.
Key Features
- Multi-component measurement: Continuous measurement of up to four gas components
- NDIR detection: Infrared detector for infrared-sensitive gases such as CO, N2O or CH4, and can be optionally fitted with up to two further electrochemical sensors for O2 and H2S as well as a paramagnetic O2 sensor
- LED display: LED-backlit display with freely-selectable dimension (ppm, vpm, mg/m3, %)
- Robust construction: Dust-tight and washable membrane keyboard, flowmeter for monitoring sample gas flow, and gas and electrical connections at the rear
- User-friendly interface: Control and function keys for seamless operation with menu-driven configuration
Technical Specifications
- CO Measurement Range: 0–100/500 PPM (selectable)
- Detection Method: Infrared (NDIR) with optional electrochemical sensors
- Optional Sensors: Oâ‚‚ (electrochemical or paramagnetic), Hâ‚‚S
- Display Type: LED-backlit with adjustable contrast
- Display Unit Options: ppm, vpm, mg/m³, %
- Supply Voltage: 120V AC (unit variant dependent)
- Frequency: 50/60 Hz
- Sample Gas Flow: Approximately 100 ml/min (with purging gas)
- Connections: Rear-panel gas and electrical ports
- Mounting: Available as bench-top or 19″ rack unit
- Keyboard: Dust-tight, washable membrane type
Typical Applications
- Furnace and boiler combustion monitoring
- Power plant emission control
- Chemical process gas analysis
- Environmental monitoring and compliance reporting
- HVAC system optimization
- Industrial exhaust and waste gas analysis
Compatibility & Replacements
The 7MB2335-1CR00-5AA1 is part of the Siemens ULTRAMAT 23 series (7MB2335 product line). This unit can be paired with legacy sensor modules and integrates with standard industrial control systems via analog outputs. Customers upgrading from earlier NDIR analyzer models may use this unit as a drop-in replacement when electrical and gas port configurations match. Verify voltage (AC/DC), frequency, and sensor range compatibility before replacement.
