ABSTRACT:
The specification discloses an electrically-operated marine craft speedometer in which velocity-indicative pitot tube impact pressure is conveyed through a conduit to a pressure transducer carried by the speedometer case. An electrically-actuated speedometer readout display mounted on the case is driven by electrical control circuitry which receives an electrical output signal from the pressure transducer. The speedometer case is preferably provided with a pressure chamber in which the pressure transducer is disposed, and means are provided for coupling the pressure chamber to the pitot tube so as to receive impact pressure therefrom.
