Siemens SIPROCESS GA700 Operating Instructions

Procedure: Devices with hoses
1. Close the reference gas inlet and, for versions with an external reference gas pump, also the
bypass outlet.
2. Connect a pressure measuring instrument (manometer) to the sample gas outlet.
3. Carefully apply pressure of approximately 1500hPa (absolute pressure) to the sample gas
inlet.
4. Then close the sample gas inlet.
5. Wait for approximately 51 minutes until the test gas that 󹪞owed in has reached the ambient
temperature and the pressure remains stable.
Note the pressure.
6. Wait an additional 5minutes and note the pressure again.
If the pressure change is less than 28hPa, or for variants with external reference gas pump
under 34hPa, the sample gas path is adequately tight.
This value is based on the tare volume of the measuring module 7 ml and the volume of the
pressure measuring device of 23 ml.
9.6.6 Checking ULTRAMAT 7 for leaks
NOTICE
Maximum permissible reference gas pressure
Ensure that the pressure of the introduced sample and reference gas does not exceed 2600 hPa
(absolute) for a piped con󹪝guration.
Note
Test values
The test values have been de󹪝ned under the assumption that the total volume of the gas path
in the analyzer module and in the connection line of the pressure measuring device amounts to
80ml.
Procedure
1. Close the sample gas/reference gas outlet.
2. Connect the sample gas/reference gas outlet to a pressure measuring instrument
(manometer).
3. Pressurize the sample gas/reference gas path with overpressure of 100hPa.
4. Wait for approximately 1minute until the sample gas/reference gas reaches the ambient
temperature.
