Parallel plate dielectric analyzer. |
摘要 |
<p>A parallel plate dielectric analyzer is disclosed including: (a) a distance sensor for accurately measuring the varying distance between the electrodes, such as a linear voltage differential transformer (LVDT), and means responsive to the distance sensor for positioning the electrodes; (b) a force transducer for measuring the applied force on the sample and means responsive to the force transducer to give a desired force by varying the electrode spacing; (c) disposable electrodes made using thick film technology composed of a ceramic substrate with a conductor adhered to its surface; and (d) a temperature sensor built into one of the electrodes such as a platinum ring adhered to the surface of one of the electrodes and means to measure the resistance across the platinum ring. i</p> |
