OMEGA’s PX181B 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. The PX181B is fully digitally compensated for the effects of pressure and temperature change. It is extremely accurate, less than 0.3% FS reference accuracy, and less than 1% FS over its compensated temperature range.
