TMR31, TMR35
Long-term stability of electronics
≤ 0.1 K (0.18 °F)/year or ≤ 0.05%/year
Data under reference conditions. % relates to the set span. The larger value applies.
Influence of ambient temperature (temperature drift)
• Pt100 resistance thermometer:
T = ±(15 ppm/K * (full scale value of measuring range + 200) + 50 ppm/K * set measuring range) * Δ ϑ
d
Δ ϑ = deviation of ambient temperature from the reference operating condition.
