These transmitters are intended for standard applications in the area of industrial pressure. The lowest measuring range for the P30 is 0.1bar, respectively for P31 it is 0.6 bar. The highest measuring range for both versions is 0.400 bar. Permissible overload is four times the nominal span (max 600 bar).
This document provides technical specifications for the PMA P30 and P31 pressure transmitters, designed for standard industrial pressure applications. The P30 features a process coupling with an internal sealing diaphragm, while the P31 offers a flush-mounted sealing diaphragm. Both models utilize a silicon pressure sensor with an isolated thin-film strain gauge to ensure accurate measuring results with a typical conformity of 0.6%. This manual is written in German.
