MicroSensor Company develops and produces special-propose liquid level sensors and monitors for detection of liquid helium and nitrogen level in a cryogenic tank, dewar, cryostat and experimental facilities.

The high-sensitive resistance microthermometers based on bulk and film of Ge are used as sensitive elements of liquid level meter, which are placed within perforated thin stainless steel tube. The special probe is extremely sensitive and highly repeatable.

The microthermometers can provide not only detection of liquid level, but measurements of temperature distribution in the cryostat. The microthermometers can also provide indication of liquid level and measurement of temperature below 4.2 K.
