ESCC-Qualified Temperature Sensors for High-Reliability Applications
One of IST AG’s key areas of expertise lies in temperature measurement. In an interview with Tom Hall, a representative of IST AG, he explained that the company has developed ESCC-qualified platinum RTD temperature sensors designed specifically for space and other high-reliability environments.
These sensors are built with a platinum structure on a ceramic substrate – a combination that ensures exceptional stability and minimal drift over extended operational periods. Short platinum wires connect the sensing element, which can be paired with ESCC-certified cables available in five different configurations. Users can choose between nominal resistances from 100 Ω to 2000 Ω, allowing for flexible integration into various measurement systems.
The sensors operate across a temperature range from –200 °C to +200 °C, covering nearly all thermal scenarios encountered in satellites, launch vehicles, or scientific instruments. Their precision and long-term stability make them a preferred choice for temperature monitoring, calibration, and safety functions in critical space applications.
Versatile Technologies for Complex Measurement Tasks
Beyond temperature sensing, IST AG offers a wide range of sensor technologies. These include humidity, conductivity, and flow sensors, which are applicable in life support systems, fuel cells, or liquid circulation systems. The company’s subsidiary Sensatec develops force, torque, and strain sensors made from stainless steel, engineered for high accuracy and robustness.
Another area of innovation lies with infrared emitters from Infrasolid, a subsidiary specializing in analytical and detection systems. The product range also includes enzymatic biosensors that react to biochemical processes and are used in medical and life science applications. This technological diversity highlights IST AG’s strong in-house development capabilities and its ability to deliver complete sensing chains tailored to complex requirements.
Why Sensor Technology is Vital for Space Missions
In modern space missions, success depends largely on the quality of measurement data. Sensors monitor temperature, pressure, electrical currents, and chemical reactions – serving as the “sensory organs” of satellites and spacecraft. Accurate sensor data enables efficient control, resource optimization, and early detection of anomalies.
Temperature and humidity sensors are especially critical for thermal management, ensuring optimal operating conditions for electronics, propulsion systems, and batteries.
The ESCC qualification achieved by IST AG for its temperature sensors represents a high level of trust and technical excellence. It confirms that these products not only perform under laboratory conditions but also prove their reliability in the harsh realities of space.
