Excerpt from Disclosures on a Precipitation Indicator, Moisture Detector, Vacuum Ball Valve, Film Strip Printer, Normal Incidence Interferometer, Color Sorter, and Coaxial T The physical mounting and configuration of the Teflon insulated 8 depends upon the application of the detector. In the sensor in 2, the insulated wires 20 are supported on a slender plastic rod One end of each wire is connected to a terminal 22 mounted on one the ceramic pillars 23. This sensor may be inserted in the earth or her hygroscopic substance to detect the change in moisture content it may be partially immersed in a body of liquid to show level changes. Miniaturized version can be inserted in a small hole drilled in a tree 0 detect the rise and fall of sap and water.
