5-Point Traceable Calibration High Stable Wet/Dry Differential Pressure Transducers

The wet/dry transducers from OMEGA are rugged stainless steel transducers that are suitable for automotive, industrial, or aerospace applications where only a single side of the transducer is exposed to wet media. These transducers provide the excellent performance characteristics of the Micro-Machined Silicon Series Transducers at a lower price than the wet/wet models.

They can be used in filter monitoring, factory, test benches, air flow or pneumatic air, pitot tubes, air speed and other aerospace or industrial application requiring a very robust wet/dry transducer. The solid state silicon core offers long, reliable service life with superior long term stability.
