Siemens SITRANS P320 and P420 SIL-Rated Smart Pressure Transmitters with HART®

Siemens SITRANS P320 and P420 are the first pressure transmitters on the market to feature remote safety handling, specifically designed for applications where safety is critical: in industries such as chemical, oil and gas, and power generation. Their remote safety handling via SIMATIC PDM saves time during SIL commissioning: rather than manually attending to each individual device across a facility, operators can program transmitters from the control room.

Both models have an increased proof test interval (up to 15 years) over other available devices on the market, significantly lowering maintenance costs. Plus, their reduced response time (down to 105 mS) optimizes the process efficiency by speeding up the control system’s response to changing application environments.

Both the SITRANS P320/420 include a new larger and improved HMI display, showing users the device’s status at a glance. Setup is convenient and quick through standard four-button programming, NAMUR NE107 support and a quick start wizard.

Key Specifications

  • Models available for gauge pressure, differential pressure, absolute pressure, flow, and level
  • Accuracy: ±0.065% (SITRANS P320) or ±0.04% (SITRANS P420); Long-Term Stability: ≤0.125% over 5 years
  • Proof test interval up to 15 years dramatically reduces maintenance costs
  • Reduced commissioning time due to remote safety handling (programming from the control room over HART® protocol and Siemens' SIMATIC PDM)
  • SIL-2/3 certification: Developed according to IEC 61508 standards
  • HART7 communications standard
