Ultra
Precision Interchangeable Thermistors
U.S. Sensor’s ultra precision interchangeable thermistors are highly
accurate, stable devices designed specifically for temperature sensing
and control applications. They are particularly suited for uses where
their precision interchangeability eliminates the necessity for costly
individual circuit calibration.
Features
• High accuracy
• Fast thermal response
• Long life
• R/T Curve-matched
Options
• Special lead materials and lengths
• Special encapsulants or probe housings
• Non-standard resistance values and tolerances
Specifications
• Thermal time constant: 1 second max. in a well
• Dissipation constant: 1 mW/˚C
• Maximum power rating: 30 mW at 25˚C derated to 1 mW at 125˚C
• Interchangeability tolerance of ±0.05˚C from 0-50˚C
• Operating temperature: -55˚C to +80˚C
