Linear rapid temperature change test chamber: refers to the temperature rise rate is uniform, each time period of temperature rise and fall rate is the same, if in a certain period of time, the setting of the heating rate is 25 degrees per minute, then it in this entire time period of the heating rate is 25 degrees per minute fixed unchanged, will not sometimes be 20 degrees per minute, or sometimes 30 degrees per minute, the same reason, the cooling rate is the same
.
In short, the speed of the temperature rise and fall is controlled
by the PID of the test chamber instrument.
Nonlinear rapid temperature change test chamber: the temperature rise and fall rate is fast at the beginning, and the cooling speed is slower
the further you go to the back.
If in a certain period of time, the temperature rise is sometimes 25 degrees per minute, sometimes 20 degrees per minute, sometimes 30 degrees per minute, but during this time, it is on average 25 degrees per minute heating or cooling instead of linear means that the average is 25 degrees per minute, there will be floating, the temperature rise and fall rate of this process is not controlled
by the instrument PID.
Linearity can only be achieved 25 °C /min, nonlinearity can be achieved 30 °C / min rapid temperature change test chamber nonlinear and linear in the same temperature range of temperature rise and fall time is the same
.
The temperature range of rapid temperature change is generally -40 ~ 85 °C
