Rated 5 out of 5 by from Just the Best Since these USB-enabled transducers are performing perfectly in a unit operations lab at the University of Kansas, they are now installed in a new undergrad fluid mechanics lab experiment at the University of Delaware

If 500 psi is the maximum line/static pressure that can be applied to both sides of the sensor simultaneously, how can these PX409s go up to a measurement range of 1000 psid?

Asked by: ChrisB
On the 1000 PSID range units. A static pressure 500 psi above the rated differential pressure range (1500 PSI) can be applied simultaneously to both ports.

Can a wet/wet differential pressure transducer be used to measure differential vacuum pressures? (i.e. absolute pressures at both process connections which are less than the ambient pressure surrounding the transducer body)?

Asked by: SeanS
Thank you for your inquiry. Most differential transducers will not handle this application unless you purchase a unidirectional product? Please contact us to discuss in detail. Hope this was helpful

Can this also be used for sensing air pressure?

Asked by: ScoutK
Thank you for your inquiry. Our Tech Support engineer has emailed you the specifications for our PX409-10WDWUI, Differential pressure transmitter. Unfortunately, we do not offer any differential sensors with sanitary connections. This sensor has 1/4 NPT male thread connections and all stainless steel wetted parts. You might be able adapt the fitting to some sort of quick disconnect setup. Smallest range we offer is a 0 to10"wc.
