The Model P4 pressure transducer features adjustable zero and full scale. Utilizing all welded construction and extremely stable electronics, this transducer provides highly accurate pressure measurements in harsh environments. The Model P4 is available in absolute and differential pressure models with input to output isolation.







  • All Tavis transducers can be supplied for corrosive media applications. Materials used for this purpose are 17-4PH SS, 17-7PH SS and Iconel . Specify model P104 for this feature.
  • Closer tolerances and higher temperature operation may be supplied. Consult factory for special requirements.
  • Add 0.5 inches to length for absolute units with ranges less than 5 psia.
