The 20102 butt bonded foil type T (Copper/Constantan) thermocouple temperature sensor series from RdF offer high performance and are ideal for demanding applications. These surface thermocouples provide an accuracy of ±1°C or ±0.75% with a fast response time of 0.5s (ungrounded) and 0.25s (grounded) for the sensor to reach 63.2% of a change in mounting surface temperature. This type T thermocouple offers an operating temperature range of -250°C up to +350°C. The 20102 series from RDF utilises butt bonding which produces thermocouples with no increase in thickness or mass at the junction. This offers a micro-foil® thickness of 0.0128mm (0.0005″). The sensors have a removable Kapton® frame for bare foil application.
