DESIGN DIAMOND SEMICONDUCTOR PRESSURE TRANSDUCER
Journal Title: Periódico Tchê Química - Year 2018, Vol 15, Issue 30
Abstract
Pressure sensors play an important role in measuring variables in the control and automation systems of various processes. The purpose of this article is to study the design of a diamond semiconductor pressure sensor. In order to achieve this goal, the analysis was based on the Fourier law, but the authors made changes in the model of equations. The study was carried out using diamonds, as they are one of the promising materials for the manufacture of sensors and have high strength, thermal and radiation resistance. It was established that the output current in a semiconductor converter of the same load on the membrane does not depend on the supply voltage, which corresponds to the technical requirements developed in the converter. When determining the insulation resistance between the sensor plates, it was determined that the insulation resistance is less than 200 MW that meets the technical requirements.
