Available in three tolerance classes: Class A (IEC 60751), Class 1/3, Class 1/10. Temperature Coefficient of Resistance (Alpha): 0.00385Ω/Ω/°C Nominal. Available in Single and Dual Element Styles in Some Sizes. Operating Temperature Range -196 to 600°C with Tolerances Assured Over the Specified Temperature Range for Each Class. Ceramic Body with Palladium-Gold Alloy Lead Wires. Suggested Operating Current: 1 milliamp max. More
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 1/3, Temperature Range -100 to 350°C, Tolerance = ± 0.10+(.0017 * t) °C
Class 1/10, 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.

Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. Six types with which the engineer is likely to come into contact are: thermocouples, resistive temperature devices (RTDs and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices.
Choose the right temperature measurement instrument for your application...
It is not practical to compare RTDs and thermocouples generally. However, if we compare their performance in terms of specific criteria, we can see which is best suited for specific applications. Thermocouples are best for working at high temperatures. New manufacturing techniques have improved the measurement range of RTD probes, but more than 90% of RTDs are designed for temperatures below 400°C.
In contrast, some thermocouples can be used at up to 2500°C. Thermocouples are generally cheaper than RTDs...
