10K Smart NTC temperature probe sensor It is a commonly used resistive element for measuring temperature changes, with its resistance decreasing as temperature rises. NTC temperature probe sensors can be connected to any circuit to measure temperature variations in humans or other materials. The typical operating temperature range of NTC temperature probe sensors is from –55°C to 125°C, though the specific range depends on the sensor’s resistance value.
The material of the NTC temperature probe sensor housing depends on the required temperature range, response time, cost, and specific considerations, such as UL, FDA, or NSF requirements for food‑grade and/or medical applications. Available materials include stainless steel, copper, plastic, polytetrafluoroethylene (PTFE), brass, aluminum, epoxy, and heat‑shrink tubing.
Our company manufactures epoxy‑encapsulated NTC temperature probe sensors. The radial conductors are 30‑AWG PVC twin‑parallel wires, rated for temperatures up to 105°C and featuring insulated conductors. This is a widely used smart NTC temperature probe sensor.
10K Smart NTC temperature probe sensor Characteristics:
1. High measurement accuracy

3. Fast response and compact size.
4. It can operate stably over long periods.
The rated resistance at 5.25℃ can range from 1 kΩ to 1000 kΩ.
The nominal resistance at 6.25°C is 10 kΩ.
7. Dissipation factor: ≥3.0 MW/°C in still air.
8. Thermal time constant: ≤12 seconds in still air.
9. Operating temperature range: -45°C to +105°C.
NTC temperature probe sensor Applications include air‑temperature sensors, surface‑temperature sensors, and immersion‑type temperature sensors. The housings of air‑temperature sensors are typically simple and inexpensive, such as molded plastic enclosures, deep‑drawn brass or aluminum cylinders, or stainless‑steel tubes. Surface sensors are designed to conform to the contour of the target surface, whether it is flat, curved, or circular. Mounting holes or clamps are often provided to facilitate sensor installation. Immersion‑type temperature sensors are engineered so that the sensing element is surrounded by the medium being measured—usually a liquid. The sensing portion usually extends through one or more openings, while a portion of the assembly remains outside the medium to enable signal readout. Immersion housings are typically threaded to allow them to be screwed into holes or openings. The immersed section must be protected against liquids and moisture.
