EDL’s Rolling Roller Sensors were engineered for use on round, rotating or stationary surfaces. Equipped with a four-ball bearing design that acts as a restrictor preventing excessive pressure to the band, this sensor is assured long life and consistent temperature measurements – with excellent repeatability. A Kapton coating is available to provide more protection for delicate surfaces. For higher temperature blocks or permanent installation, please contact us for pricing and solutions. This sensor is available with a Nylon Block (RRB) or 2.5″ Handle (RRH).
