5.2 Pressure and Flow rates for Test Air and/or Reference Air
The systems are factory-set to the correct amounts of test air and/or reference air.
The instrument air versions are designed for an inlet pressure of 2-10 bars. With a higher inlet pressure of 6 bar,
it is necessary to readjust the flow of reference air and/or test air.
The flow rates should be in the following range:
Test air: 150l/h - 180l/h
Reference air: 30l/h - 40l/h
The flow of reference air can be checked in the actual value menu [SYS MENU System Information
Actual measured value]. In systems with integrated pneumatic unit, test air and/or test gas flow is displayed during
calibration or system test.
5.3 Adjusting Flow Rate (SME 53 with Pneumatics)
In the instrument air version in the Safe Area housing with an integrated pneumatic unit, it is possible to adjust the
reference and test air at the electronic unit.
In this respect, the pump and instrument air versions are different:
In the pump version, only the flow rate of test air can be adjusted.
In the instrument air version, both flow rates (test air and reference air) can be adjusted.
