SIL 2/3 Certified
Siemens SITRANS P320 / P420 Digital Pressure 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.
