Pressure measurement and selection of pressure sensor in aircraft engine room

Published on: September 1, 2020 by Zetian sensing

How to develop a method that can continuously and accurately read the pressure data of the aircraft engine compartment, then, the heat, vibration, impact and other factors must be fully considered. The conventional method is to spend as long as several months to do the test. However, we must need an accurate and stable pressure sensor, which can play a role in the changing environment Produce correct and repeatable results.

 Application of pressure sensor in Aeroengine

When selecting pressure sensor for Aeroengine pressure measurement, the first problem is often Pressure sensor Heat resistance. The pressure sensor will get hotter and hotter on the side of the engine of the aircraft; therefore, we must make sure whether the pressure sensor can be installed separately or whether a heat insulation device is needed? More importantly, when the temperature of other components is higher and higher, can the pressure sensor still work normally? After eating, the size of the pressure sensor is also very important. Small size pressure sensor can be easily fixed by universal fixture or any other ready-made bracket, without spending time to design a custom installation method.

In the pressure measurement of aero-engine, the measurement must ensure that it does not pollute the engine oil and does not reduce the sealing performance of the material. Zetian sensor has a variety of solutions to achieve this standard, including the use of EPDM and fluororubber to ensure that the pressure sensor runs at the best performance throughout the test process. Of course, we can choose the metal sealing scheme to ensure the correct test results. More importantly, maybe we need a front mask connection, using pur cable and current output signal together. Zeta sensing can provide an accurate combination to ensure that during the connection process, electrical and output signals, pressure connections and seals are all we need. In essence, the pressure sensor is an extremely important part in the test process, and is definitely not a component in a simple test setup.  

In general, we need to design a series of hydraulic tests; however, in most tests, many factors will be controlled. Heat resistance, fixation, pressure range and a number of other problems will change during the test. In order to solve all of these problems, we need to be able to cover these problems to the test pressure transmitter, and continuous acquisition of accurate results.
