These “KN” Series wire wound platinum sensing elements are available in three tolerance classes:
Class A, Temperature Range -100 to 450°C, Tolerance = ± 0.15+(.002 * t) °C
Class 1/3B, Temperature Range -100 to 350°C, Tolerance = ± 0.10+(.0017 * t) °C
Class 1/10B, Temperature Range 0 to 100°C, Tolerance = ± 1/10*( 0.30+(.005 * t)) °C
with t = temperature in °C regardless of sign.
Note: These elements are capable of being exposed to temperatures between -196 and 600°C, however the tolerances apply only within the temperature ranges shown for each class.
These elements are made with wire wound platinum coils, ceramic housings and palladium-gold alloy lead wires. The small size of the sensor body allows for easy installation in protective tubes or custom housings. Applications include a variety of processes and equipment.
