Description

This upgraded HT-NTC100K thermistor module utilizes a Negative Temperature Coefficient (NTC) thin-film sensing element, packaged within a 304 stainless steel sheath to ensure precise and reliable temperature feedback. The internal resistance packaging protects the sensitive element, providing stable readings and a longer service life compared to exposed probes.

The module is engineered for high-temperature environments, such as 3D printer hotends and industrial heating blocks, where it effectively replaces K-type thermocouples. Its 1-meter cable with high-temperature Teflon insulation minimizes signal interference over distance, a common issue with thermocouple wiring, leading to more consistent temperature control and improved print or process quality.

Key Features

  • High-precision NTC B3950 thermistor with 100KΩ resistance at 25°C and ±1% tolerance.
  • Wide temperature measurement range from -50°C to +320°C, optimized for high-temperature applications.
  • Durable 304 stainless steel probe housing (3mm diameter, 15mm length) for direct thermal coupling.
  • High-temperature Teflon (PTFE) insulated cable, 1 meter long, resistant to thermal degradation.
  • Pre-attached 2-pin terminal connector for simplified integration into control systems and heated blocks.
  • Packaged sensing element provides superior stability and lifespan compared to exposed thermistor beads.
  • Designed as a direct, interference-resistant drop-in replacement for K-type thermocouple sockets.

Applications

  • High-temperature 3D printer hotend and heated bed temperature monitoring and control.
  • Replacement sensor for CNC machines, plastic extruders, and industrial ovens using K-type thermocouple sockets.
  • Temperature feedback in DIY reflow ovens, soldering stations, and thermal processing equipment.
  • Environmental chamber and laboratory heating system temperature profiling.
  • Embedded temperature sensing in custom electronics projects requiring a robust, wired probe.

Frequently Asked Questions

What is the operating temperature range of this NTC thermistor?

This NTC B3950 thermistor is rated for continuous operation from -50°C to +320°C. The 304 stainless steel sheath and high-temperature Teflon cable are designed to withstand this extended range, making it suitable for high-temperature 3D printing filaments and industrial heating applications.

Can this sensor directly replace a K-type thermocouple in my 3D printer?

Yes, this module is designed as a direct, plug-and-play replacement for K-type thermocouples in compatible heater blocks and control boards. It provides a more stable resistance-based signal that is less susceptible to electrical interference over long cable runs, which can improve temperature control stability.

How do I wire the 2-pin terminal connector?

The two wires are terminated in a standard 2-pin screw or push-in terminal block. Polarity does not matter for a basic thermistor circuit. Simply connect the two wires to the designated thermistor input terminals on your mainboard (e.g., Creality, Prusa, Duet) or temperature controller, ensuring a secure connection.

What is the benefit of the stainless steel sheath?

The 304 stainless steel sheath protects the internal NTC element from physical damage and corrosive environments. It ensures efficient thermal transfer to the sensing element and provides a durable, long-lasting probe suitable for repeated insertion into heated blocks and harsh industrial settings.
