The pressure sensor device of using under a kind of high voltage environment
Technical field
The present invention relates to the pressure sensor device used under a kind of high voltage environment, particularly relate to a kind of pressure sensor device that is applicable to the pipeline discharge pressure of electric field measurement in high voltage liquid or melt.
Background technology
In the commercial production such as oil, chemical industry, alkaline, chemical fibre, pharmacy, food, can encounter the situations such as high temperature, high pressure, high burn into high viscosity to the measurement of medium (solution, melt), these successfully solve in modern industry.If but the measured medium of encountering is in the situation that high-voltage electric field (several ten thousand volts), that all can be with the high voltage induction loop with the pressure transducer of line or transmitter etc.Because general circuit is withstand voltage all only below kilovolt, this will cause catastrophic consequence.
