Differential Pressure Transmitter
DPA Series
-
Adtek has multiple transmitters which can be applied on different types of work environment. To have a better quality of life, buildings with central centilation system (CVS) become a trend, so we recently developed a new product, DPA, indoor differential pressure transmitter. The users can set up the measured range according to the actual use, and make zero adjustment for the differential pressure. Besides being equipped with regular analog outputs, we also added RS-485 output to DPA which is a simple and low cost communication tool connecting with monitoring system.
