SITRANS P320 / P420
Digital Pressure Transmitter for High Precision & Safety Applications
Siemens SITRANS P320 / P420 Transmitter
Product Summary
SITRANS P320/P420 are the first pressure transmitters equipped with remote safety handling. This innovative capability enables engineers to program all devices conveniently directly from the control room instead of visiting each individual transmitter on site.
This dramatically shortens commissioning time, especially in critical industrial applications that demand functional safety. A proven proof test period of up to 15 years (compared to the standard 2 years) ensures minimal maintenance overhead and maximized operational uptime.
Key Benefits
Designed for high reliability, process stability, and safety
Remote Safety Handling
Dramatically reduced commissioning time via remote safety configuration directly from the control room.
15-Year Proof Test Interval
Proof test intervals extended up to 15 years (vs. the standard 2 years) for lower maintenance cost and higher uptime.
User-Friendly Interface
Clear graphic display with NAMUR NE107 diagnostic icons and an intuitive quick start wizard.
