Negative Temperature Co-efficient

BetaTHERM Sensors is a leading provider of high precision NTC (Negative Temperature Co-efficient) thermistors and temperature probe assemblies. Our range of NTC thermistors and temperature probe assembles are suitable for a wide range of temperature measurement, temperature control, and temperature compensation applications.

Sectors served include Biomedical, Aerospace, Instrumentation, Communications, Automotive and HVAC&R (Heating, Ventilation, Air conditioning & Refrigeration). BetaTHERM serves best in applications where end product functionality is dependent on thermister quality, accuracy, reliability and fast-time response.

BetaTHERM offer a range of products to meet your requirements. These include:

  • Leadless Chips - Gold chips, Silver chips
  • Leaded Thermistors - Epoxy Thermistors, Glass Thermistors, Polyimide & Mylar Thermisters,
  • SMD’s (Surface Mount Thermistors) - 1206, 0805, 0603, 0402
  • High Reliability Aerospace Components
  • Standard and Custom Temperature Probe assemblies - Biomedical, Instrumentation, HVACR, Aerospace, etc.

With over 20 years of experience in temperature sensors, BetaTHERM have built upon the inherent advantages of NTC thermistors and offer the following skills and capabilities to design engineers:

  • High accuracy temperature solutions - Typical Interchangeability: ±0.05°C
  • Miniaturised thermistors: Minimum OD: 0.35mm
  • Customisation - Optimising the specific electrical and mechanical requirements of each application
  • Design flexibility - rapid sampling and prototyping.

The particular features and advantages of NTC thermistors compared to other temperature sensor types include:

  • Large temperature sensitivity, of the order of -4% to -6% per °C.
  • Available in many physical forms for temperature probe configurations.
  • Thermistors are not subject to standards or constrained by material types. This gives many options for customization of mechanical and electrical characteristics.
  • Tight tolerances available (typically +/-0.1°C, +/- 0.2°C and customized values).
  • Interchangeable devices eliminate need for individual sensor calibrations.
  • Standard two-wire connection system.
  • Good electrical noise immunity.
  • Easy to interface to electronic instrumentation.
  • Can be customized to optimize thermal response.
  • Relationship between resistance and temperature of NTC thermistor sensors can be modelled easily by standard equations.
    Temperature range can be extended from -100°C to + 300°C with special constructions.
