The PX181 has been discontinued. Please see the PX181B as a possible substitute or
contact our Pressure department.
OMEGA’s PX181 Series pressure transducers combine state-of-the-art semiconductor technology and durability resulting in a high accuracy general purpose pressure sensor. The 1 to 5 volt output assures compatibility with most process controllers and computer interface equipment. Applications include engine monitoring and testing, HVAC, compressors, etc. The silicon sensor is bonded on a glass pedestal to isolate it from induced stresses, provide wide media compatibility, and the stainless steel pressure port permits use with corrosive substances. These rugged, compact transducers exhibit 0.3% accuracy and excellent interchangeability.
