Custom Temperature Sensors For Aerospace IndustryAs a major supplier to the aerospace aftermarket, the customer needed to design a custom temperature sensor assembly that was part of a larger electro-mechanical subassembly. Replacing just the sensor probe was a more cost effective solution than replacing the entire assembly. The temperature sensor assembly included three separate thermocouple probes wired in series to measure the average temperature of the three locations. Critical to temperature measurement was a low resistance specification for the interconnecting wire between the sensor probes.In aerospace applications, it is critical that replacement parts meet the specifications of the original part. The major challenge with this applications was meeting the wire resistance specifications within the dimensional requirement for the sensor assembly. Durex' engineering team designed the thermocouple sensors using a very low resistance coiled MI cable. Production fixturing was developed to consistently produce the entire sensor assembly. The customer had a temperature sensor probe solution that was far more cost effective than replacing the entire electro-mechanical assembly.
