WIKA operating instructions model TFT35
4 ... 20 mA 0 ... 10 V
±(0.3 + 0.005 * t) °C (class B per IEC 60751)
±0.5 % of measuring span
Overall accuracy = accuracy of measuring
element + accuracy of electronics
Example:
Medium temperature t = 150 °C
Measuring range 0 ... 200 °C
→ ±(0.3 + 0.005 * 150) + 0.5/100 * 200 = ±2.05 °C
