I need a barometric pressure transmitter that can measure ambient air pressure in a chamber and provide a 4-20 mA output signal. The normal operating range is a pressure just above atmospheric pressure around 1013 to 1400 mbar. The application is to provide a feedback of chamber pressure in order to control blower speed to regulate the pressure in the chamber. Apart from measurement, does the DMP 331 i also have a digital display of pressure?
Yes the DMP331i can be scaled to output a 4-20mA signal over a the range you are interested. It is possible to supply the PA430 plug-on digital display which connects between the fixed plug and mating socket of the DIN plug connector.
