Sea water, fresh water, air, fuel and oil pressures are monitored by Tavis transducers every day, and on some of the most sophisticated land and sea-based vehicles in the world. Our customized acceptance testing assures that whether at a cold depth of 100 fathoms or a dusty speed of 100 mph, all your pressure measurements are reliable and accurate.


Tavis land and sea vehicle applications involve such features and capabilities as:
  • High corrosion resistance
  • Small dynamic pressure signal detection amid very high static pressures
  • User-defined, tuned frequency response characteristics
  • Contamination tolerance and particle traps
  • Specialized shielding and filtering for operation near strong EMI sources
  • 2- and 3-wire current loop outputs and 4-wire voltage outputs

  • 1 The designs above are intended to convey just a few capabilities previously used in critical flow systems for discussion purposes. Tavis specializes in custom configurations and capabilities for your specific application. Discuss your vehicle requirements with our engineers for your specific flow control needs.
  • 2 Many error band definitions and limits are possible, and these actual error bands are too specific to delineate herein. A clear definition and understanding of any error band is critical, and many manufacturers’ published errors or accuracies can be very misleading. Please consult Tavis regarding your specific error band requirements.
