7.6 Sensor response time
Sensor response times are generally indicated as "50% time" (t
05
) and "90% time" (t
09
). "50%
time" refers to the time needed for a temperature sensor signal to achieve 50% of its end value
in the face of erratic temperature changes (this applies analogously to "90% time").
Compact sensor with thermowell, with measuring element Pt100 RTD
The transmitter response time is <10 ms.
