Kapton Bracket Style Thermocouple – The Watlow Kapton thermocouples, when used with the aluminum bracket, has been designed primarily to measure roller temperature. By putting a light pressure on the roller, the Kapton thermocouple measures roller surface temperature without using slip rings. This type of set-up greatly reduces lag time and eliminates the cost of slip rings and their associated maintenance problems. It can also be used to measure conveyor belt temperatures or any other moving part by riding gently on the part surface.
Low Profile Kapton Thermocouple (without Bracket) When used without the bracket the Watlow Kapton thermocouple can be placed between heated parts for accurate temperature measurement. At the thermocouple junction, the overall thickness is only 0.016 inch (0.4 mm), so that it doesn’t interfere with thermo conductivity.
Kapton Peel and Stick This sensor needs no bracket and no special mounting. Simply peel away the backing and the self-adhesive film will bond to almost any surface. Temperature ratings for continuous use is 400°F (200°C).
