Siemens SITRANS SL In-situ Gas Analyser

Siemens SITRANS SL In-situ Oxygen Gas Analyser is designed for measuring oxygen (O2) with high sensitivity. It consists of a pair of cross-duct sensors, a transmitter unit and a detector unit, both with the same dimensions. Due to its little installation effort and its minimum maintenance requirements, SITRANS SL guarantees a high level of economic efficiency.

The gas analyzer SITRANS SL consists of a pair of cross-duct sensors, a transmitter unit and a detector unit. The hardware processes the measurement signal into a concentration value as well as monitors, controls and servs the communication. The sensors can operate under harsh conditions. Measurements are carried out with a short response time permitting effective cost-savings. The laser characteristics allow single-line spectroscopy free of interferences which means that only the gas component of interest will interact with it and other process influences are eliminated.

Special features of the SITRANS SL:

• Little installation effort
• Minimum maintenance requirements
• Extremely rugged design
• High long-term stability through built-in, maintenance-free reference gas cell
• Real-time measurements

Moreover, the analyzer provides warning and error messages:

• When maintenance is required
  • With large variations in the reference signal
  • With poor signal quality
• If the transmission violates an upper or lower limit

• Control of combustion processes
• Process optimization
• Plant and operator safety
• Process measurements in all types of power and combustion plants
• Process control
• Explosion protection
• Measurements in corrosive and toxic gases
• Quality control
