...
Where: Directly on the metal surface of the cryogenic tank itself, under the MLI (multi-layer insulation), touching the tank’s skin.
How many: Often 8–20, spaced around the circumference and length (top, mid, bottom).
Purpose: Detect hot spots, cold spots, and how evenly the tank is cooled.
...
- Sensors: thermocouples(mixing of fluid), pressure sensor(LN_2 boils off easily), liquid level sensor(detect sloshing and boil off), flow meter(how much fluid is being moved), IMU/accelerometer(identify periods of microgravity), voltage sensor(how much heat is added for induced stratification)
Baffle and Pump Cryogenic Flow Test - Testing that the pump and baffle system can mix stratified fluid to make it homogenous. Test using liquid nitrogen or oxygen that is allowed to sit(causing the top to warm and create heat stratification), then turn on the pump(and spin the cylinder on a turntable if possible) to measure the temperature equalization.
- Sensors: thermocouples(prove destratification), pressure transducer(moniters tank pressure for safety), optional flow meter or liquid level sensor to see how other variable are affecting the destratification
Thermal Vacuum Test:
Testing the thermal emissivity (tendency to lose heat energy) and outgassing (escape of boil off through the tank walls in a vacuum environment).
