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
- Allows precise measurement
- Repeatable
Highly controlled manufacturing process
- Ensures wide temperature range
- Stabilizes physical and chemical attributes
