Space grade NTC thermistor | Space qualified temperature sensors | ISRO qualified sensors | TNT-10116-L501

Satellites and spacecraft venture into a realm of extremes. In this environment, accurate temperature measurement is crucial. Regular thermometers wouldn't last a minute in space, that's where space-qualified temperature sensors are required, THERMOSEN have got space qualification from ISRO (Indian Space Research Organization) for NTC thermistors to be used in satellite


Thermosen Space-qualified temperature sensors are specially designed to endure the harshness of space. They undergo rigorous testing to ensure they can withstand:


Extreme temperatures: Spacecraft experience vast temperature swings, from the blistering heat near the sun to the bone-chilling cold in deep space. These sensors need to function flawlessly across a wide range.


Radiation exposure: Space is bombarded with radiation, which can damage electronics. Space-qualified temperature sensors are built with radiation-resistant materials and designs to maintain accuracy.


Vacuum: The near-vacuum of space can cause components to outgas (release trapped gases) which can affect performance. These sensors are specially sealed to prevent this.


Space-qualified temperature sensors play a critical role in various spacecraft functions:


Thermal management: Sensors help regulate the temperature of sensitive electronics, preventing overheating or freezing.

Scientific data collection: For missions studying planets or stars, accurate temperature readings are essential for understanding the environment.

Propulsion systems: Monitoring engine temperatures is crucial for safe and efficient operation.
