Does Differential Air Pressure Sensor 1139_0 work with CO2?

Post by Rhybot »

I am wondering, what gases can the Differential Air Pressure Sensor (PN 1139_0) work with?

Will it work with a mixture of 95% air and 5% CO2?

Depending whether CO2 has more or less volume than air, you could expect a positive or negative change in pressure vs air alone (ideal gas law). But I would expect the sensor to measure the correct pressure regardless of composition of the gas being measured.
