Series 1 BetaCurve Bare leaded Thermistors Introduction Features The BetaCURVE Thermistor Series I are small epoxy coated devices with solid tin plated lead Fast time response (1 second typical in wires. The series offers a choice of precision temperature tolerance classifications for a wide liquids). variety of customer applications, such as temperature measurements, temperature indication, o DC (Dissipation Constant) = 0.75 mW/ temperature control, and thermal compensation. C typical in still air at 25C. The BetaCURVE Series history oflong ter stability and reliability performance have been Available in custom probe assemblies. demonstrated in critical medical, scientific instrumentation, military/aerospace and industrial o applications. Tight tolerance available +/ 0.1 C o o Thermistor interchangeability has become an important factor for cost efficiency in advanced from C to 70 C. thermal performance applications. The need for expensive individual thermistor calibration is not Proven Stability and Reliability. necessary. The BetaCURVE Series interchangeability means that each device will match the Min./Max Temperature Exposure = published ResistanceTemperature Characteristics for a given thermistor and will be within the 80C to +150C. specified deviation (tolerance, ie. 0.1C, 0.2C, 0.5C and 1.0C) limits over the temperature range 0C to 70C. Alloy lead wires for reduced thermal conductivity stem effec). Shape and Dimensions Applications Temperature sensing, control and compensation. Medical equipment and patient monitoring. Aerospace instrumentation and crystal oscillator compensation. Liquid or gas temperature control and monitoring. Assembly into probes for a wide variety of applications.
