Tavis sensors are currently monitoring cockpit instrumentation cooling air pressures on fighter jets, measuring bleed air pressures on military aircraft, indicating torque pressures on commercial turboprops, keeping UAVs aloft with fuel system controls, and more. Landing gear braking system pressures and even airliner waste tank level sensors are also part of the Tavis aircraft repertoire.
Existing designs provide capabilities such as:
Existing designs provide capabilities such as:
- Contamination tolerance and self-draining features to handle ingestion of debris and moisture.
- Δ-Δ pressure measurements (comparing 2 differential pressures to each other in a single instrument – e.g. upstream and downstream flow rates)
- Bi-directional overpressures:
- Proof pressures as high as 333 times full scale
- Reverse proof pressures as high as 133 times full scale
- Connector or pigtail configurations
- Voltage or current loop output
- Wet – Wet capability without the need to coat or protect diaphragm (non-contact, metallic diaphragm without any electrical connections)

- 1 The designs above are intended to convey just a few capabilities currently used on aircraft for discussion purposes. Tavis specializes in custom configurations and capabilities for your specific application. Discuss your application requirements with our engineers for a smooth flight.
- 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.
- 3 Frequency Response given is for electronics only. Actual frequency response will depend on pressure range and media.
