Information

Cryogenic pressure sensors are relatively new to the public, and you may have heard of them. The main reason for this is that the application of cryogenic pressure sensors is far away from most people's work and life. It is mainly used for low-temperature storage, low-temperature scientific experiments and pressure measurement of storage tanks in aerospace and submarines.

  1.What is a low temperature pressure sensor

The cryogenic pressure sensor adopts the stainless steel integrated packaging structure, and the pressure sensing film adopts a special design, so that the sensor can work stably in the ultra-low temperature -196℃ environment. Its advantages are small size, especially high measurement accuracy, which brings convenience to scientific research, high dynamic response frequency, strong corrosion resistance, long service life . Even if the cost is high, but the long term value is much higher than its own value. In the future of the development of science and technology, cryogenic pressure sensors will be used more and more widely.

  1. Working principle of low temperature pressure sensor

If we use the pressure gauge to measure the pressure of liquid hydrogen and liquid nitrogen, the data can only be recorded by manual observation, which increases the input of manpower and also has the possibility of missing important data. And if we use the impulse pipe , then measured with an ordinary pressure sensor, there will be a large volume . At the same time, there will be errors due to the length of the impulse pipe. Therefore, in this special case, the small volume cryogenic pressure sensor plays an important role. The cryogenic pressure sensor can directly measure the pressure in the ultra-low temperature environment, configure the transmitter, and form an intelligent monitoring system.

 

Since the working temperature of the cryogenic pressure sensor may reach nearly -200℃, how to reduce the impact of temperature drift is the difficulty of manufacturing the cryogenic pressure sensor. At present, there are not many manufacturers that can produce the cryogenic pressure sensor .

 

PPM-S316B cryogenic pressure sensor is a liquid nitrogen pressure sensor , made by Changsha Taihe Electronic Equipment Co., Ltd . It adopts stainless steel integrated packaging structure, and the pressure sensing film adopts excellent special design, so that the pressure sensor can work safely and stably in the ultra-low temperature environment of -196 ℃, with small volume, high measurement accuracy, high dynamic response frequency, strong corrosion resistance and long service life.

  1. Installation of low temperature pressure sensor

When you choose a cryogenic pressure sensor, you should check the product certificate and its instructions, and check carefully to avoid mistakes. When installing the cryogenic pressure sensor, check whether the field interface is consistent with the product interface according to the product connection mode and screw type. If it is a screw interface, tighten it slowly and pay attention to sealing. Torque cannot be directly added to the transmitter shell, but can only be added to the six sides of the pressure interface. If any abnormality is found in the process of use, turn off the power immediately, stop using and check. The storage place should be in a cool, dry and ventilated warehouse.
