KONG Lin, SU Jian-jun, LI Zhi-rong, et al. A way to restrain the response of thermal impact of a pressure sensor[J]. 2010, 29(12): 69-72. DOI: 10.13873/j.1000-97872010.12.030.
Because pressure sensor in shockwave pressure test can not shield high temperature
the pressure testing value of the burning phase of thermobaric dynamite always departures the truth.For restraining the response of thermal impact of pressure sensor
a solution that daubing lipin on the top of pressure sensor is presented
which could control increasing temperature of the top of pressure sensors.The influence of thickness of lipin on the frequency response function is analyzed.The feasibility is validated by experiments.The conclusion is that daubing linpin on the top of pressure sensors is a convenient
and efficient way to block off the heat.The thinnest lipin which satisfied the time of restraining the heat and not over affect the frequency response characteristics is chosen
the correct value of the pressure at the burning phase can be achieved.
