The PX480A series has been replaced by the new and improved PX190 series. Many ranges are in stock, available for immediate shipment.

OMEGA’s PX480A Series transducers, designed for general industrial and commercial requirements, offer excellent performance in a wide range of applications. They are based on proven micro-machined silicon technology, providing high reliability, long-term stability, and low cost. They are extremely accurate with less than 0.3% FS reference accuracy. Wetted parts are made of 316L stainless steel for a wide range of media compatibility.

it says this is replaced by the PX-190 but that sensor is gauge only and not absolute. I need an inexpensive sensor that measures suction pressure on the inlet manifold so it will go negative gauge. will the px-190 work?

Asked by: JasonK
The PX190 will not work in your application. Possible substitute for the PX480A would be PX309-030AV.
