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 -200 to 650°C (-328
to 1200°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

Applications for the Watlow RTD for Use with Thermowells

• Air conditioning and refrigeration servicing
• Furnace servicing
• Stoves and grills
• Textile production
• Plastics processing
• Petrochemical processing
• Micro electronics
• Air, gas and liquid temperature measurement
• Exhaust gas temperature measurement
