Thin Film
Platinum RTD’s
U.S. Sensor’s thin film platinum resistance temperature detectors (Pt-
RTD) consist of a thin film platinum deposited on a ceramic substrate.
Thin film Pt-RTD’s provide cost advantages when compared to wire
wound Pt-RTD’s because of their lower material cost factor.
Features
• Glass coated platinum element
• Virtually linear relationship between temperature and resistance
• Capable of withstanding temperatures ranging from -50˚C to +500˚C.
• High accuracy: Resistance and temperature
• High Reliability: Capable of withstanding extreme
• Available in various probe configurations for specific
• Excellent stability even at high temperatures
Specifications
• Thermal time constant: 15 seconds max. (moving air)
• Dissipation constant: 2 mW/˚C (moving air)
• Maximum applied current: 1 mA
Higher temperature ratings are available by special order
deviation can be controlled to within ±0.06% and
±0.15˚C, a tolerance that corresponds to Class “A” of
IEC 751 or 1/2 DIN of DIN 43760
