Introduction of Cryogenic Level Sensor

Cryogenic level sensors are devices used to measure cryogenic liquid level. They are widely used in scientific research, medical equipment, and other fields. Different types of cryogenic level sensors have different sensitivities and precisions. They can be used to measure the level of liquid nitrogen and other inert liquids.

Cryogenic level sensors are stable at extremely low temperatures and are suitable for cryogenic environments. Sino-Inst’s cryogenic sensors are accurate and reliable in extremely low temperature environments. For specific needs, the level range can be customized to meet the requirements of different applications.

If you want to measure the pressure of a cryogenic medium, you can use: cryogenic pressure sensor.

If you want to measure the flow of a cryogenic medium, you can use: cryogenic flow meter.

Applications of Cryogenic Level Sensor

Cryogenic level sensors are used in many fields. They are mainly used to measure and monitor liquid levels under extremely low temperature conditions.

Industrial Refrigeration
It is used in frozen food processing and cold storage. It monitors the liquid level of cooling tanks and cryogenic storage tanks.

Medical Field
Cryogenic level sensors is used for low temperature storage of biological samples. Such as liquid level monitoring in liquid nitrogen tanks to ensure the safe preservation of biological samples.

Ships
In the cryogenic storage tanks of ships, the liquid level of liquid fuel or coolant is monitored to ensure the normal operation of the ship.

Aerospace
Low temperature test of the common bottom tank of the launch vehicle. It monitors the liquid level of cryogenic media such as liquid nitrogen and liquid oxygen, and provides important data for rocket thrust estimation and propellant management.

Energy Storage
In liquefied natural gas (LNG) storage equipment. It monitors the liquid level of LNG to ensure smooth storage and transportation.

How Does a Capacitive Level Sensor Work?

The capacitive level sensor is based on the principle of capacitive induction. When the height of the measured medium soaking the measuring electrode changes, its capacitance changes. It can convert the change of the liquid level medium height into a standard current signal. The current signal is transmitted to the operation control room for centralized display by secondary instruments or computer devices.

Its good structure and installation method can be applied to high temperature, high pressure, strong corrosion, easy crystallization, anti-blocking, anti-freezing and solid powdery and granular materials.

The capacitive level sensor solves the influence of factors such as temperature, humidity, pressure, and conductivity of the material on the measurement results. Therefore, it has extremely high anti-interference, reliability and high precision.
