Performance characteristics of PMC71 ceramic pressure

transmitter (Sensor module + Electronic module)

Reference operating

conditions

• As per IEC 60770

• Ambient temperature TA = constant, in the range +21 to +33 °C (+70 to +91 °F)

• Humidity j = constant, in the range: 5 to 80 % RH ± 5 %

• Ambient pressure pA = constant, in range: 860 to 1060 mbar (12.47 to 15.37 psi)

• Position of measuring cell: horizontal ±1° (see also "Influence of the installation position" section

→  42)

• Input of LOW SENSOR TRIM and HIGH SENSOR TRIM for lower range value and upper range value

• Zero based span

• PMC71 material of the process isolating diaphragm: Al2O3 aluminum oxide ceramic FDA,

ultrapure 99.9 %

• Supply voltage: 24 V DC ±3 V DC

• Load with HART: 250 Ω

• Turn down, TD = URL /|URV |; zero based span

Preamble

The performance characteristic of the transmitter refers to "Accuracy of the transmitter". The factors

influencing accuracy can be divided into 2 groups

• Total performance of transmitter →  33

• Installation dependent influencing factors →  42

Total performance of

transmitter

Transmitter total performance →  35 comprises the reference accuracy, ambient temperature

effect and it is calculated by the formula

Total performance = ± √ ( (E1)² + (E2)² )

E1 = Reference accuracy →  34

E2 = Ambient temperature effect per 28°C (per 50°F) →  36
