Watlow RF style RTDs feature high accuracy probes with a number of lead options and coiled spring strain relief to protect the leads against sharp bends in the transition area.

Watlow's platinum resistance elements are specially designed to ensure precise and repeatable temperature versus resistance characteristics. Watlow RTDs are made with controlled purity platinum, have high purity ceramic components, and are constructed in a unique strain-free manner.

Ceramic elements are extremely precise and stable within the wide temperature range of -200 to 650°C (-328 to 1200°F). Patented strain-free construction provides dependable, accurate readings and allows elements from different lots to be substituted without recalibration. High signal-to-noise output increases accuracy of data transmission and permits greater distances between sensor and measuring equipment. Temperature coefficient (alpha) carefully controlled while insulation resistance values exceed DIN-IEC-751 standards, ensuring sensor sensitivity, minimizing self-heating, allowing precise measurement, and repeatable results.

Applications include air conditioning and refrigeration servicing, furnace servicing, stoves and grills, textile production, plastics processing, petrochemical processing, micro electronics, air, gas and liquid temperature measurement, and exhaust gas temperature measurement.
