The Tavis Model P8 transducer is ideally suited to applications requiring very low differential pressure measurements. Available in pressure ranges as low as 0.01 psid, this differential pressure transducer features low power consumption and zero and full scale adjustments. The all welded stainless steel construction and a stable electronics package combine to produce an extremely accurate, but rugged unit.





  • All Tavis transducers can be supplied for corrosive media applications. Materials used for this purpose are 17-4 PH SS, 17-7 PH SS and Iconel . Specify model P108 for this feature.
  • Closer tolerances and higher temperature operation may be supplied. Consult factory for special requirements.
  • This unit is also available in a two wire 4 to 20 mA configuration. Add C following model number for this feature.
