Mean-Sensing Transducer

A transducer which measures the mean or average value of the input waveform but which is adjusted to give an output corresponding to the r.m.s. value of the input when that input is sinusoidal.

Measuring Element

A unit or module of a transducer which converts the measurand, or part of the measurand into a corresponding signal.

Measuring Range

The part of the span where the performance complies with the accuracy requirements.

Medium Distribution (Lighting)

A luminary is classified as having a medium light distribution when its max candlepower point falls between 2.25MH 3.75MH TRL. The maximum luminaire spacing-to-mounting height ratio is generally 7.5 or less.
