Challenges and concept

The test system for CO₂ measuring cells was developed for high-precision validation of measuring cells used in industrial plants to determine CO₂ concentration in gaseous media. Testing under defined pressure conditions must be precise, reproducible and designed for high volumes.

Precise pressure tests

Pressure-tight multiple testing of CO₂ measuring cells

For this purpose, MCD Elektronik implemented a pressure-tight test chamber made of solid stainless steel, which is flooded with CO₂ and pressurized to up to 2.5 bar. This allows real operating conditions to be reproduced and the measuring cells to be validated under reproducible conditions.

Up to 20 units can be tested in parallel in one test run. Pressure-resistant encapsulated measurement lines prevent leaks and distorted measurements, while the robust design supports reliable continuous industrial operation.

FAQS

The tested measuring cells are used to precisely determine the carbon dioxide concentration in gaseous media. In industrial environments, they are used, for example, in analytical measuring instruments, process plants or monitoring systems that control environmental conditions in industrial facilities.
Testing takes place in a pressure-tight stainless steel chamber flooded with carbon dioxide. A test pressure of 2.5 bar is also applied to test up to 20 units in parallel under defined gas and pressure conditions. This assesses whether the measuring cells deliver reproducible values under realistic loads and respond stably to the specified atmosphere.
All measurement channels connected to the units under test must be routed out of or integrated into the test chamber in a pressure-tight manner. This is technically demanding because electrical signals, measurement lines and contacts must operate reliably without compromising the pressure tightness of the gas chamber. At the same time, the channels must not distort measurements and must remain stable over repeated pressure cycles.
The test system is based on a standard ULC rack and uses the central TestManager CE software solution, an MCD control unit and a customer-specific user interface integrated into the MCD software solution via Toolmonitor. Connection to the iTAC MES system and a barcode scanner for unambiguous identification of the units under test are also integrated.
In industrial or medical technology environments, the focus is primarily on reproducible measurement conditions, stable process parameters and reliable integration into the production process. The real measurement task must be reproduced in a controlled manner. Complete documentation and reliable separation of good and rejected parts are also important.
