Abstract
A capacitance probe having a relative thin profile and large cross section for use in short yet relatively large diameter desiccant beds is formed from two substantially identical members, each having a network of strip elements electrically and structurally connecting a plurality of plate elements. Upon inverting and rotating one member with respect to the other member, the plate elements of one member are interleaved with the plate elements of the other while leaving enough space to accommodate a sufficient volume of sorbent to serve as the dielectric. The probe may be employed with supporting circuitry to detect the advance of the moisture front as a change in dielectric constant of the sorbent. There is also provided a system to connect the two members in nonconducting relation so that a rigid structure results.
