Checking Calomat 7 For Leaks; Local Commissioning - Siemens SIPROCESS GA700 Compact Operating Instructions

5.4.2.3

Checking CALOMAT 7 for leaks

Procedure
1. Connect a pressure measuring instrument (manometer) to the sample gas outlet.
Measuring range approx. 200 hPa rel. to 1000 hPa rel. with appropriate measured value
resolution (0.1 hPa).
Absolute pressure gauges with correspondingly good resolution are also suitable.
2. Connect the sample gas inlet to a compressed air source via a shutoff mechanism. The valves
in use must provide a leakage rate <10
3. Pressurize the analyzer module step-by-step with an overpressure of 400 hPa.
4. Close the shutoff mechanism and wait for 5 minutes until the sample gas that flowed in has
reached the ambient temperature.
5. Note the pressure.
6. Wait 5 minutes. Note the pressure again.
If the pressure change lies under 5 hPa, the sample gas path is adequately tight.
This value is based on the tare volume of the measuring module 6 ml and the volume of the
pressure measuring device of 23 ml.
