Siemens SITRANS P320/420 Digital 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 Digital Pressure Transmitter represents the pioneering pressure transmitters featuring remote safety management, allowing users to program all devices from the control room rather than individually on-site, reducing commissioning time, particularly in applications with safety requirements. Furthermore, the extended test period of up to 15 years, as opposed to the typical 2 years, results in reduced maintenance expenses.
