With traditional transducers, one transducer is required for each measure-
ment that you need. With the DPMS, one transducer can make multiple
measurements. In fact, you can take up to 37 measurements simulta-
neously with just one DPMS unit! This means you can
often specify one DPMS instead of multiple transducers.
With direct communications capability, think of the
savings that can be achieved in every aspect of a new
project. Not only is it easier for Engineering, the DPMS
will also save on wiring and valuable panel space.
