Dielectric sample holder for thin sheet insulation

THE DIELECTRIC SAMPLE HOLDER described was designed for the purpose of measuring the dielectric properties of thin sheet insulation from room temperature to 600 C. The frequency to be covered was from power frequency to 100 kilocycles and the sample thickness ranged from 0.001 inch to 0.050 inch. In the design, considerations were given to a method of applying heat, ease of changing samples, accuracy of measurement and the time required to obtain the data. The holder was designed to connect to the type 1610A General Radio Capacitance Measuring Assembly or any similar type capacitance bridge.
