Sensore di pressione

Sensore di pressione

Overview

A change in gas 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 is a sensor module available as option in addition to a RITTER MultiGas NDIR or NDUV sensor. The measured pressure value is displayed in the provided software.
