Overview
A change in the gas and/or atmospheric pressure causes a change in the number of molecules per volume and thus a change in gas density. This density change in turn has a significant influence on the result of the concentration measurement by the sensor. By measuring the gas pressure inside of the sample cell (cuvette), the value of the concentration measurement is compensated / corrected.
The pressure sensor enables an increase in the accuracy of the gas analysis measurement by a factor of 15:
The pressure sensor is always integrated into the RITTER »MultiGas« NDIR sensors as a micro-sensor. It is optionally available for the NDUV sensors and is built into the sensor casing. The measured pressure value is displayed in the provided software.
