Precision
Interchangeable Thermistors
U.S. Sensor’s precision interchangeable thermistors are low cost, highly
accurate, stable devices designed specifically for temperature sensing and
control applications. They are particularly suited for uses where their pre-
cision interchangeability eliminates the necessity for costly individual cir-
cuit calibration.
Features
• High accuracy
• Fast thermal response
• Low cost
• Small size
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 stirred oil bath, 10
• Dissipation constant: 1 mW/˚C
• Maximum power rating: 30 mW at 25˚C derated to 1 mW at 125˚C
• Interchangeability tolerance of ±0.5˚C or ±1.0˚C from 0-70˚C
