Definition of transducer in English:



  • A device that converts variations in a physical quantity, such as pressure or brightness, into an electrical signal, or vice versa.

    • ‘At least one fluid device from a group consisting of a flow controller, a valve, a filter and a pressure transducer is provided.’
    • ‘Could these gene products represent upstream components in a common signal transduction pathway such as a receptor or signal transducers?’
    • ‘The input transducer is the photo detector that detects the radiation emitted from the radiated substance.’
    • ‘Leaf elongation rate was calculated from daily increments in leaf length using linear voltage displacement transducers connected to a data logger.’
    • ‘The orientation of the depressions depends on the type carrier for the transducer.’
    • ‘The capacitive coupling between the different electrodes allows the position of the transducer to be determined.’
