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
