≤ 0.15 % of URL per year
The measured error comprises the non-linearity including hysteresis and non-reproducibility in accordance
with the limit point method as per IEC 60770.
PMC131
• ≤ 0.5 % of (URL - LRL) x TD
Example: PMC131 version "A1R"
• Nominal value = 10 bar
• Upper range value (URV) = 6 bar
• Lower range value (LRV) = 0 bar
Turn down (is set at factory):
• Nominal value / (URV – LRV)⏐= 10 bar/6 bar = 10:6
