Answer Posted / senthil
The output of pressure switch is the contact changeover, i.e. from NO (normaly open) to NC (normally close) or vice versa, when the pressure setpoint is crossed in either way.
Whereas the output of Pressure transmitter is 4 to 20 mA or 1 to 5V as the case may be with the type of transmitter you are using.
