text: Capacitive sensors are the most commonly used devices for the detection of
humidity because they are inexpensive and the detection mechanism is very specific
for humidity. However, especially for industrial processes, there is a lack of
dielectrics that are stable at high temperature (>200 °C) and under harsh conditions.
We present a capacitive sensor based on mesoporous silica as the dielectric in
a simple sensor design based on pressed silica pellets. Investigation of the structural
stability of the porous silica under simulated operating conditions as well as
the influence of the pellet production will be shown. Impedance measurements demonstrate
the utility of the sensor at both low (90 °C) and high (up to 210 °C) operating
temperatures.
