球式傾斜儀
For tilt
applications where a visual indication or
measurement is required, Fredericks ball bank
indicators are ideal. A ball bank indicators are
comprised of a glass tube, bent to a specific
radius, which determines its angular range. A ball
is inserted in the tube, then the tube is filled
with a clear, wide-temperature-range fluid and
hermetically sealed. Decals and paint are applied
based on the individual customer’s requirements.
Ball bak indicators are assembled under the most
exacting standards using fixtures, processes, and
tooling developed by our engineers. This allows us
to offer a product that will provide years of
consistent performance and reliability no matter
what the application.
Typical applications include
aircraft instrumentation, hospital bed-angle gauges,
recreational vehicle tilt warning, and inclination
indicators for sailing vessels. When your application
demands a rugged, reliable visual tilt indication,
Fredericks inclinometers provide a practical, accurate,
and economical solution.
