Which definition most accurately describe when to use a pressure switch and when pressure

transmitter?

Select one alternative:

a pressure switch is used when we don't need to measure exact value of a pressure but

rather activate (open or close) the valve when a set pressure threshold (value) is

reached, while pressure transmitter is used to continuously measure the values of

pressure in the system

a pressure switch is used when we need to continuously measure a value of a pressure

in the system, while pressure transmitter is used as a switch that activates (e.g. open or

close the valve) when a set pressure threshold is reached

pressure switch and pressure transmitter represent the same device (sometimes one

term is used over the other depending on industry), thus it is not important when to use

pressure switch or pressure transmitter, both are equally fine

none of the above definitions are correct
