16.3 Performance characteristics of metal process
isolating diaphragm
16.3.1 Reference operating conditions
• As per IEC 60770
• Ambient temperature T
A
= constant, in the range of:+21 to +33 °C (+70 to +91 °F)
• Humidity φ = constant, in the range of 5 to 80 % rH
• Ambient pressure p
A
= constant, in the range of:860 to 1
060 mbar (12.47 to 15.37 psi)
• Position of measuring cell = constant, in range: horizontal ±1° (see also "Influence of the
installation position" section → 14)
• Zero based span
• Process isolating diaphragm material: AISI 316L (1.4435)
• Filling oil: NSF-H1 synthetic oil in accordance with FDA 21 CFR 178.3570
• Supply voltage: 24 V DC ±3 V DC
• Load: 320 Ω (at 4 to 20 mA output)
16.3.2 Measuring uncertainty for small absolute pressure measuring
ranges
The smallest extended uncertainty of measurement that can delivered by our
standards is:
• in the range 1 to 30 mbar (0.0145 to 0.435 psi): 0.4 % of reading
• in the range < 1 mbar (0.0145 psi): 1 % of reading.

16.3.4 Resolution
Current output: min. 1.6 μA
16.3.5 Reference accuracy
The reference accuracy contains the non-linearity [DIN EN 61298-2 3.11] including the
pressure hysteresis [DIN EN 61298-23.13] and non-repeatability [DIN EN 61298-2 3.11]
in accordance with the limit point method as per [DIN EN 60770].
