The transducer includes an oscillator the output of which is a function of a measurement being made. The display unit presents the measurement made in quasi-analog and/or digital form either in a conventional format such as a circular dial face, linear form such as a column 82 or in other selected formats of various geometrical configurations and/or in various mathematical progressions to suit particular applications.
