High temperature pressure sensor for engine working processes control

During the engine tests the working processes control is conducted. Among others such control requires different pressure measurements. The most of the processes are accompanied by the working environment temperatures rise, which may be highly essential. Contemporary means of pressure measurements, which are used in automatic systems for the engine tests control are intended for work in temperature range up to 80ОС. Unlike known the suggested high temperature pressure sensor ensures precision of measurements at the expense of compensation of errors, which appear during pressures definition at high environment temperature. The sensor permits to widen of temperature range up to 400ОС. For that the additional measurements error doesn’t exceed 0,5%.
