Inconel 718 and 304L CRES materials are used in our satellite transducers because of their compatibility with caustic propulsion media such as MMH, NOX, MON-3, etc. Most satellite transducer designs manufactured by Tavis utilize a ¼-inch tube stub for orbital tube welding into the spacecraft manifold tubing. The tube stubs are typically seamless 304L or 321; however, some designs incorporate a Titanium-to-304L transition tube for use with Titanium spacecraft plumbing.

- 1 The designs above are intended to convey just a few capabilities currently used on satellites for discussion purposes. Tavis specializes in custom configurations and capabilities for your specific application. Discuss your application requirements with our engineers for your spacecraft’s long-term success.
- 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.
