Application scenarios of low-temperature resistant vacuum pressure switches

Low-temperature resistant vacuum pressure switches have significant applications in multiple temperature-sensitive fields that require precise pressure control. The following are their main application scenarios:

Aerospace field

Spacecraft propulsion systems: In the propulsion systems of spacecraft, propellants such as liquid hydrogen and liquid oxygen need to be stored and transported in extremely low-temperature environments. The low-temperature resistant vacuum pressure switch can monitor the pressure changes in the propellant pipeline in real time. When the pressure exceeds the set range, it will promptly send a signal to ensure the safe and stable operation of the propulsion system and prevent propellant leakage or system failure caused by abnormal pressure.

Spacecraft environmental control system: To maintain a suitable environment inside the spacecraft, it is necessary to precisely control the pressure inside the cabin. In low-temperature environments, such as when spacecraft are exposed to extreme low temperatures in space, low-temperature resistant vacuum pressure switches can monitor the pressure parameters of the environmental control system, ensuring stable pressure inside the cabin and providing astronauts with a safe working and living environment.

Low-temperature experimental equipment

Superconducting experimental device: Superconducting materials can only exhibit superconducting properties in extremely low-temperature environments. In superconducting experimental devices, such as superconducting magnet systems, it is necessary to maintain a low-temperature environment to ensure the superconducting state. Low-temperature resistant vacuum pressure switches are used to monitor the pressure inside low-temperature containers, preventing abnormal pressure from affecting the conduct of superconducting experiments and ensuring the safety of experimental equipment at the same time.

Low-temperature physics experiment equipment: In low-temperature physics experiments, such as studying the properties and phase transitions of substances at low temperatures, the experimental equipment needs to operate in a low-temperature and pressure-stable environment. The low-temperature resistant vacuum pressure switch can monitor the pressure changes of the experimental equipment in real time, providing accurate pressure data for the experiment and ensuring the reliability of the experimental results.

Equipment related to liquefied natural gas (LNG

LNG storage and transportation equipment: Liquefied natural gas needs to be stored and transported at extremely low temperatures (approximately -162℃). In LNG storage tanks, transport tankers and other equipment, low-temperature resistant vacuum pressure switches are used to monitor the pressure inside the tank or tanker, preventing excessive pressure from causing safety valves to trip or equipment damage, and at the same time avoiding low pressure from affecting the normal storage and transportation of LNG.

LNG refueling station: In an LNG refueling station, pressure monitoring of refueling equipment, gas storage tanks, etc. is required. Low-temperature resistant vacuum pressure switches can accurately measure pressure in low-temperature environments, ensuring the safety and stability of the gas filling process and preventing safety accidents caused by abnormal pressure.

Polar scientific research equipment

Equipment in polar research stations: In polar research stations, many devices need to operate in low-temperature environments, such as refrigeration equipment and low-temperature experimental instruments. Low-temperature resistant vacuum pressure switches can monitor the pressure parameters of these devices, ensuring their normal operation and providing support for scientific research work.

Polar exploration instruments: Instruments used for polar environmental exploration, such as meteorological observation equipment, geological exploration equipment, etc., may operate in low-temperature environments. Low-temperature resistant vacuum pressure switches can ensure the stability of the internal pressure environment of the instrument, guarantee the measurement accuracy and reliability of the instrument, and provide accurate data for polar scientific research.
