Which formulation most accurately defines a detection sensor?

Select one alternative:

detection sensors transform the measured quantity into a discrete output signal i.e. in a

Morm of on/off signal (e.g. detection of object presence or detect object position, limit)

detection sensors transform the measured quantity into a discrete output signal i.e. in a

form of on/off signal (e.g. measurement of temperature, flow, pressure, force)

detection sensors transform the measured quantity into a continues output electrical

signal (e.g. detection of object presence or detect object position, limit)

detection sensors transform the measured quantity into a continues output electrical

signal (e.g. measurement of temperature, flow, pressure, force)
