Ir Analyzer Unit - Siemens ULTRAMAT 23 Series Equipment Manual

Description
3.4 Technical specifications
Operation of analyzers in hazardous areas
For safe operation of the analyzer in hazardous areas, it is essential to observe the information
and conditions referred to in the "ATEX compact operating instructions for ULTRAMAT 23".
3.4.2

IR analyzer unit

To ensure compliance with the technical specifications, a cycle time of ≤ 24 hours must be
activated for the AUTOCAL. The technical specifications are based on a sample gas pressure of
1013 ±5 hPa absolute, a sample gas flow of 1.2 ±0.2 l/min and an ambient temperature of
25 ±2 °C.
