The Watlow specialty RTDs are available in six styles: 6 inch adjustable spring style, 12 inch
adjustable spring style, adjustable armor style, cartridge with flange, open air, open air with
flange and surface mount. These Watlow RTDs are also available in multiple diameters and lengths.
Watlow RTDs
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.
Performance Capabilities
Ceramic elements are extremely precise and stable within the wide temperature range of -50 to 260°C
(-58 to 500°F).
Patented, strain-free construction
Provides dependable, accurate readings
Allows elements from different lots to be substituted without recalibration
High signal-to-noise output
Increases accuracy of data transmission
Permits greater distances between sensor and measuring equipment
Temperature coefficient (alpha) carefully controlled while insulation resistance values exceed
DIN-IEC-751 standards
Ensures sensor sensitivity
Minimizes self-heating
