Additional Features

The PX165 differential pressure transducer series provides a solution to measure differential pressure in low and ultra low ranges, down to 0.25 inches of water. These sensors are quite compact, coming in at only 1.18"" x 1.65"" x 0.37 and weigh just 0.35 oz. this makes them ideal for circuit board (PCB) mounted applications or when space is at a premium. They come standard with pins but are also compatible with a JST BHR-03VS-1 connector for quick electrical connections. A particular advantage to purchasing this low differential pressure solution from Omega is the flexibility to order large quantities for OEM applications or lower quantities that are reasonably priced for small projects.

The Static Pressure should be applied to both ports simultaneously to avoid exceeding the Proof Pressure rating.

The new PX165 series also serves as a suitable replacement in many cases for our PX160 series that contained PX162, PX163, and PX164 part numbers.
