Measurement of air pressure
Thread Content
The pyrolysis gas generated by the pyrolyzer has a complex composition, including particulates and vaporized oils. Under such conditions, how should the pressure of this gas be measured? The pressure range is from -100 to +100 Pa; what type of instrument would be suitable for this purpose? Please help, thank you
Honeywell STD110-E1H-00000-HC,FB,SM,S2,CC,TG,3H – differential pressure transmitter. This is the model I selected for one of my projects; it belongs to the HONEYWELL STD110 series. This post was last edited by hwindforce on 2009-3-2 at 16:12
Thin film flange? I don’t quite understand. Could you explain it more clearly?
The pressure range you’re using is too low – 100 Pa positive or negative. The composition of the feed gas is also quite complex. If there isn’t much variation in the flow of air in the surrounding environment, I would recommend using a differential pressure gauge (transmitter) with one or two diaphragms for measurement, with the negative side connected to air.
