Currently these are the only Pt temperature sensors approved by the European Space Agency.
The sensors are resistant to thermal cycles – they provide stable measurement results at 70,000 cycles in the temperature range.
They are also very drift stable, have a small size of 2.3mm x 2mm x 1.3mm are light and robust as they have no moving parts.
The devices are available with resistors from Pt100 to Pt2000 and correspond to tolerance Class B (IEC 60751 FO.3). They are available as an engineering model as well as a flight model.
If requires IST also offers customer-specific adaptations of the sensors for example with extended wires (ESCC qualified wires).
