Description

This sensor utilizes a Negative Temperature Coefficient (NTC) thermistor, where electrical resistance decreases predictably with increasing temperature. The B3950 curve provides a highly repeatable and accurate response, though the relationship is non-linear. For precise temperature conversion, it is recommended to use the specific resistance-to-temperature lookup table or Steinhart-Hart equation provided in the component’s datasheet, rather than a linear approximation.

The probe is constructed with a sealed stainless steel sheath, offering protection against moisture and physical damage. The long 5-meter cable allows for remote placement of the sensing element from the data acquisition or control unit, making it suitable for monitoring temperatures in hard-to-reach locations within machinery, enclosures, or environmental spaces.

Key Features

  • Precision B3950 NTC thermistor with 10KΩ ±1% resistance at 25°C.
  • Stainless steel probe housing (5mm diameter, 25mm length) for durability and corrosion resistance.
  • Extended 5-meter, 2-wire cable with industry-standard XH2.54 connector for secure mating.
  • Broad operational temperature range from -20°C to +105°C.
  • Low thermal dissipation constant of 5mW/°C to reduce measurement error from self-heating.
  • High probe insulation resistance (>100 MΩ) ensures signal integrity and isolation.
  • Compact form factor suitable for embedding into assemblies and equipment.
  • High-value build optimized for reliable performance in cost-sensitive applications.

Applications

  • HVAC system temperature monitoring and control for air handlers and ductwork.
  • Industrial process control and equipment temperature sensing in machinery and enclosures.
  • Aquarium, terrarium, and hydroponic system environmental monitoring.
  • 3D printer heated bed and enclosure temperature feedback.
  • DIY electronics projects and data logging systems requiring a robust, long-reach temperature probe.

Frequently Asked Questions

What is the resistance value and tolerance of this NTC thermistor?

This sensor uses a B3950-type NTC thermistor with a nominal resistance of 10 kilo-ohms (10KΩ) at 25°C, with a tight tolerance of ±1%. This precise base resistance ensures accurate and repeatable temperature measurements when used with the appropriate conversion curve or lookup table.

What is the temperature measurement range and what type of connector does it use?

The sensor is rated for continuous temperature measurement from -20°C to +105°C. It is terminated with a standardized 2-pin XH2.54 connector (2.54mm pitch), which is commonly used for secure connections to microcontroller breakout boards, data loggers, and custom wiring harnesses.

How do I convert the thermistor's resistance reading to a temperature value?

The B3950 NTC thermistor has a non-linear resistance-to-temperature relationship. For accurate conversion, you must use the specific Steinhart-Hart coefficients or the resistance/temperature lookup table provided in the component's datasheet. Simple linear approximations will result in significant error, especially at the extremes of the operating range.
