SITRANS P320 Pressure Transmitter

Digital pressure transmitter with advanced diagnostics and SIL 2/3 capability.

Where it fits

Built for plants running a Siemens-native asset management stack: the diagnostics surface in the same tooling as the control system, so instrument health is visible where the engineers already work rather than in a separate application nobody opens.
