Si-Planar-Pellistor 的热时间常数在几毫秒范围内。因此，可以用高达约 100 Hz 的频率来调节其工作温度。化学反应的非线性特性会在传感器信号中产生谐波，可用于气体检测。本文演示了测量设置，将测量结果与理论结果进行比较，并介绍了一种通过温度调整传感器选择性的方法。
The Si-Planar-Pellistor has a thermal time constant in the range of several milliseconds. Therefore it is possible to modulate its operating temperature with frequencies up to about 100 Hz. The non-linear characteristics of chemical reactions generate harmonics in the sensor's signal which can be used for gas detection. The paper demonstrates the measurement setup, compares measurements with theoretical results and introduces a method to adjust the sensor's selectivity by temperature.
