Performance characteristics

Response time
≤ 3 s with transmitter
Reference operating conditions
• Matching temperature (ice bath) 0 °C (32 °F) for Pt100 sensor
• Ambient temperature 25 °C ± 5 °C (77 °F ± 9 °F) for transmitter
Maximum measured error
Electronics
0.1 K (0.18 °F) or 0.08%. % relates to the set span. The larger value applies.
Sensor (Pt100) for version without transmitter
• Tolerance class A as per IEC 60751, operating temperature range -50 to 200 °C (-58 to 392 °F) with neck
• Maximum measured error in °C = 0.15 + 0.002 ⋅ ⏐T⏐
⏐T⏐ = Numerical value of the temperature in °C without regard to the leading sign.
Total deviation of electronics + sensor
• Operating temperature range:
-50 to 150 °C (-58 to 302 °F) without neck
-50 to 200 °C (-58 to 392 °F) with neck
• 0.25 K + 0.002 ⋅ ⏐T⏐
