An Electronic Pressure-Sensitive Transducer
G Day · Journal of Scientific Instruments · 1949
A brief description is given of an electronic pressure-sensitive transducer in which the applied pressure varies the inter-electrode spacing of a double-diode valve working underspace-charge limited conditions. The resultant change in current is indicated as the out-of-balance voltage of a bridge circuit in which the diode forms two of the arms. Although primarily designed to give an electrical output as a function of aircraft height the device is readily adaptable for other applications.
