Table C–1. Performance specifications
Accuracy ± 0.15% of span (3–15, 1–17 psi, and 0.2–1.0 bar outputs)
± 0.25% of span (3–27 and 6–30 psi outputs)
Stability ± 0.5% of span/6 months
Repeatability ± 0.05% of span
Dead Band 0.02% of span
Frequency Response - 3 db at 5 Hz (ISA S26.4.3.1 Config. A)
Temperature Effect ± 0.02% per °F of span (range 0°F to 150°F / -18°C to +66°C) or ±
0.04% per °F of span (range -40°F to 150°F / -40°C to +66°C)
Vibration Effect <0.25% from 1–200 Hz/1 G
RFI-EMI Effect < ± 1% effect on zero and span (26–1000 mHz at 30 V/m) when
installed per installation guidelines (
Chapter 2 ). Refer to CE
Conformity for test standards.
Table C–2. Functional specifications
Input 4–20 or 10–50 mA
Output 6–30, 3–27, 3–15, or 1–17 psig and 0.2–1.0 bar
Supply Pressure Standard Configuration: Minimum of 3 psig and maximum of 10
psig above the maximum calibrated output (except for a 1–17
psig output, which will be 35 psig)
High Pressure Configuration: For 3–15 psi (0.2–1.0 bar) outputs,
standard supply range is 35–100 psi (2.4–6.9 bar). Some units
may be calibrated to operate using a unique range. Contact
Thermo Fisher for other output and supply ranges.
Supply Pressure Effect Not measurable within the recommended supply pressure range
Operating Current 3.7 mA minimum, 200 mA maximum: continuous at 120°F (50°C);
half-cycle 70 A, 1/120 s at 68°F (20°C)
Loop Load 3.8 Vdc ± 5 ohms (195-ohm load at 20 mA)
