Resistance Temperature Detectors

Resistance Temperature Detectors (RTDs) Ensure Precise and Repeatable Temperature Measurement

Watlow manufactures a variety of resistance temperature detectors (RTD) sensors that are specially designed to ensure precise and repeatable temperature measurement.
Watlow sensors are built to meet the most demanding industrial applications while providing a lower total cost of ownership for our customers.

Features & Benefits

Strain-free construction provides dependable, accurate readings and allows elements from different lots to be substituted with no recalibration needed

High signal-to-noise output increases accuracy of data transmission and permits greater distance between sensor and measuring equipment

Temperature coefficient (alpha) carefully controlled while insulation resistance values exceed DIN-IEC- 51 standards ensures sensor sensitivity


Optical Res Accuracy Temperature Outside Diameter
N/A DIN Class A ± 0.06% at 32°F (0°C) DIN Class B ± 0.12% at 32°F (0°C) -328°F to 1200°F -200°C to 650°C In Cm
