Get all the great performance characteristics of the Micro-Machined Silicon Transducers in these wet/wet differential pressure models. These rugged stainless steel transducers are ideal for tough industrial automotive, or aerospace applications requiring a wet/wet transducer. They can be used in test benches, fitler monitoring, hydraulic, flow, or water/wastewater applications, as well as factory or pneumatic air, pitot tubes, air speed and other industrial or aerospace applications. The solid state silicon core and all stainless steel wetted parts will provide long, reliable service life with excellent long term stability.

Rated 1 out of 5 by from Never worked on site Never worked on site and OMEGA does not have technical service to provide any satisfactory solution, the only thing they offer is selling (be it an additional calibration, an additional equipment with no assurance of working either, etc.) Awful company.

Rated 5 out of 5 by from Our standard for differential pressure transducer We run several sensors in our factory, so far with cero problems, they offer a lot of features for each sensor so you can adjust it to your specific needs
Date published: 2019-03-07
Rated 5 out of 5 by from We use tons of PX409s and 309s We use a lot of these differential transducers and the 309 Gage/absolute counterparts. They all work great, the calibration certificates are also very helpful and recommended if you want to be sure about error propagation.
