Sensors are used in Thermal Systems to measure and report temperatures at specific interesting locations such as propellant pipework, at or around instruments or to panels.
Their measurements are fed into the Thermal System control loop to enable the electronics and software to react by e.g. switching heaters.
Typical Thermistors include BETATHERM® and ROSEMOUNT® sensors.
They are normally treated as EEE (Electrical, Electronic or Electromechanic) Component and are typically procured according to special requirements.
RUAG Space purchases these items for the customer, modifies them as needed (e.g. different or longer cables) and integrates them to the space hardware.
Thermocouples for ground based test campaigns are also part of RUAG Space thermal hardware portfolio.
