EDL’s Roller Leaf Surface Sensors exert minimal pressure against the item under measurement.
This allows delicate, fast-moving flat objects to be measured precisely and without damaging the object. The leaf incorporates a latch assembly to restrict the leaf extension beyond the wheels, reducing the potential abuse to the Thermocouple element. Leafs may be replaced as needed. EDL recommends some care when storing this style sensor to prevent damage to the sensing element. All Roller Leaf Sensors come with our standard lead, one sensing leaf, and our removable extension handle.
