What is the difference between military pressure sensor and industrial pressure sensor?

Published on: August 11, 2018 by Zetian Technology

Military pressure sensor and industrial pressure sensor are the application of pressure sensor in different fields. Due to the different emphasis of military industry and civil industry on pressure sensor, the specific difference between military pressure sensor and industrial pressure sensor is caused.

First of all, from the working principle of pressure sensor, military pressure sensor and Industrial pressure sensor In principle, there is no essential difference between the two. They have the same basic theory and calculation method.

Secondly, due to the particularity of its application field, the military pressure sensor has special requirements in the following aspects, which is similar to the personalized customization of industrial pressure sensor.

Third, the working environment of military pressure sensor is generally bad. For example, the mechanical and thermal environmental conditions of space sensors are not only harsh, but also adapt to the environment of space radiation and vacuum weightlessness. Therefore, military pressure sensors generally require much higher reliability than ordinary industrial pressure sensors. In some cases, it is better to sacrifice product performance than to meet reliability first. This is also why we often see that military pressure sensors are not always the most advanced pressure sensor technology. At the same time, the military pressure sensor must undergo strict environmental test before leaving the factory. In recent years, with the development of pressure sensor technology, the new sputtered thin film pressure sensor is more and more popular in the field of military industry due to its inherent high reliability and anti harsh environment characteristics.

Fourth, the military pressure sensor is limited by the installation space size of equipment and the distribution index of static load mass. Its external structure and size are generally different from the ordinary civil pressure sensor, and the weight of the pressure sensor should be strictly required.

Fifthly, the power supply of military equipment is different from that of industrial field. The power supply capacity of military equipment is generally limited. Therefore, the power consumption of military pressure sensor is generally smaller than that of industrial pressure sensor. This is why most military pressure sensors do not use industrial standard 4-20mA output, but use voltage signal output.

Sixth, in some military equipment, such as rockets, missiles, military UAVs, etc., the pressure sensors on these equipment are usually disposable and do not need to be maintained. Therefore, the pressure sensors are required to work according to the reliability mode of "work → failure → safety".

Seventh, the demand for military pressure sensors is small, which requires special production test fixtures and specific production equipment. Compared with the mass-produced civil pressure sensors, the price of military pressure sensors is much higher than that of industrial pressure sensors with the same performance index.
