Siemens SITRANS P - Absolute Pressure from the Gauge Pressure Series

Gauge pressure measuring limits from di󹪜erential pres‐
sure series
• Measuring cell with inert oil
30 mbar a/3 kPa a/0.44 psi a
• Measuring cell with FDA-compliant oil
100 mbar a/10 kPa a/1.45 psi a
Upper measuring limit 100% of max. range (for oxygen measurement: max. 100 bar/
10 MPa/1450 psi and 60 °C ambient temperature/medium
temperature)
Lower range value Between the measuring limits (continuously adjustable)

For devices with functional safety, the minimum permissible measuring span is limited by the
turndown. Therefore, ensure that the con󹪝gured turndown is no higher than 5:1.
