Cement On Polyimide Thin Film Thermocouple - Aerostructure Grade
These versatile cement on foil thermocouples give exceptional performance for exceptional applications. Although used widely in the aerospace industry for dynamic testing of composite structures, they can be used on any application where a lightweight, miniature, durable, flexible and rugged sensor is required. This unique 0.005” thick sensor in the form of a 0.5” x 0.787” film, provides millisecond responses and high dielectric strengths combined with very low thermal mass and physical profile. The foil sensor incorporates a class 1 tolerance thermocouple sensor which is rolled flat before being embedded between two paper thin glass reinforced high temperature polymer laminates which are then high kiln fired in order for them to meet your most arduous requirements. The polyimide laminate both supports and electrically insulates the thermocouple as well as providing a flat surface for cementing or resining the foil sensor to. They feature rugged 0.010” dia Kapton leads 72” long and are available in thermocouple types K, T, J and N. They are designed for easy installation either by using the adhesive weld compound which we offer or alternatively by using an epoxy resin. Users must ensure the resin they use satisfies the operating temperature they intend working within. They have an operating temperature range of -418ºF up to 572ºF with short term use up to 700ºF. These aerostructure grade sensors can also be built to your specific dimensional requirements.
