Where above atmospherics pr is available in this case Bar is maintain

Answer / samir

mBar and Bar are both pressure unit. As per our system pressure we used the desired unit range transmitter or switches. As example if we have to measure PA fan header pressure pressure it's range very low as 5-10 Kpa,eg; 50-100mabar. So here we can used a transmitter or switches in bar unit instead Bar.
