Summary

Illustrative RTI responses to a constant 150 °C gas stream. Based on Schifiliti et al. (2002), p. 4-6, Equations 11–15; article calculation.

Original illustration for Response time index, level 3 Advanced.

Source basis: Schifiliti et al. (2002), p. 4-6, Equations 11–15; article calculation.
Alt text: Three exponential temperature curves cross 68 °C after about 11.5, 23.0 and 46.1 seconds.
Accuracy notes: The time origin is arrival of the constant exposure; no transport, conduction or water-delivery delay is included. End each curve at its stated operating threshold, avoiding an implication about post-activation element temperatures.
