Siemens SITRANS P320/420 Pressure Transmitter


  • Reduced commissioning time due to remote safety handling
  • Suitable for harsh conditions due to robust materials
  • User-friendly due to clear and large display and diagnostic icons acc. to NAMUR NE107 and a quick start wizard
  • Maintenance cost reduction due to proof test interval up to 15 years
  • Fast reaction and optimized processes due to reduced response time

Siemens SITRANS P320/420 pressure transmitters represent a pioneering advancement in the field, introducing remote safety management capabilities. This innovation allows users to centrally configure all devices from the control room, eliminating the need to individually program each transmitter on-site. This streamlined process significantly accelerates commissioning, particularly in applications demanding functional safety measures. Additionally, these transmitters offer an extended test period of up to 15 years, in contrast to the typical 2-year period, resulting in reduced maintenance expenses.
