SITRANS P320/420

The first pressure transmitter with remote safety handling

SITRANS P320/420 is the first pressure transmitter on the market to feature remote safety handling. The instruments’ 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. This reduces the commissioning time in applications requiring functional safety.

The devices are suited for applications where safety is critical: in industries such as chemical, oil and gas, and power generation.

Besides that both pressure transmitters have an increased proof test interval over other devices on the market, significantly lowering maintenance costs with testing periods of up to fifteen years rather than every two.

The reduced response time of the devices optimizes the process efficiency by speeding up the control system’s response to changing application environments.

SITRANS P320/420’s user-friendly features also include a new larger and improved HMI display, showing users the device’s status at a glance. The setup is convenient and quick thanks to four-button programming, NAMUR NE107 support and a quick start wizard.

Detail

Accuracy:0,065% (SITRANS P320), 0,04% (SITRANS P420)
Response time:down to 105 ms
Long-Term Stability≤ 0.125 % / 5 years
Measuring cells:from 20 mbar to 700 bar
SIL-2/3 certification:Developed according to IEC 61508 standards

  • Full SIL-2/3 assessment
  • Reduced commissioning time due to remote safety handling
  • Suitable for harsh conditions due to robust materials
  • User-friendly  due to clear display and diagnostic icons acc. to NAMUR NE107
  • Maintenance cost reduction due to proof test interval up to 15 years

SITRANS P500

SITRANS P500 Siemens

Description

The SITRANS P500 has been developed to meet the highest expectations for measuring accuracy, ruggedness, and user-friendliness, and it merges seamlessly into the SITRANS P family. With the SITRANS P500, you can expect pressure measurement at the highest level.

It guarantees an accuracy of ≤ 0.03 % as well as outstanding values for the influence of static pressure and temperature on the measured result. In this way, it guarantees a total performance of ≤ 0.09 % up to a turndown of 10:1. Since this feature means that only one measuring cell can be used for different measuring ranges, inventory costs can be significantly reduced without the need for losses in the quality of the measured result. The high long-term stability of the sensor also reduces maintenance costs thanks to extended calibration intervals, and ensures that you can always rely on the measured results in the long term.

An innovated sensor assembly enables direct-connected use in process temperatures of up to 125 °C (257 °F) even without a remote seal system. With an improved 3-pushbutton operator input concept for setting the device, the SITRANS P500‘s host of diagnostics options can be used conveniently without software. Even curve displays and trend diagrams can be represented on the display for user-friendly process monitoring.

SITRANS P500 is also suitable for use in safety instrumented systems SIL2 according to IEC 61508 / 61511.
