What is NTC type thermistor?
NTC stands for “Negative Temperature Coefficient”. NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current-limiting devices.
What is the resistance of NTC thermistor?
NTC thermistors are usually characterised by their base resistance at room temperature, that is 25oC, (77oF) as this provides a convenient reference point. So for example, 2k2Ω at 25oC, 10kΩ at 25oC or 47kΩ at 25oC, etc. Another important characteristic of a thermistor is its “B” value.
How is NTC thermistor measured?
As with any resistor, you can use the ohmmeter setting on your multimeter to measure thermistor resistance. The resistance value displayed on your multimeter should correspond to the ambient temperature near the thermistor. The resistance will change in response to temperature change.
How does a NTC thermistor work?
With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases. When temperature increases, the resistance increases, and when temperature decreases, resistance decreases. This type of thermistor is generally used as a fuse.
What does NTC stand for on a temperature sensor?
Negative Temperature Coefficient
NTC is an acronym for Negative Temperature Coefficient. TE Connectivity (TE) is a leading designer and manufacturer of high precision discrete NTC thermistors, probes, and assemblies. An NTC thermistor is a temperature sensor that uses the resistance properties of ceramic/metal composites to measure the temperature.
What is NTC approved?
Philippines’s Radio Type Approval consists of certification by the NTC (Philippines’ National Telecommunications Commission). The NTC is the government agency responsible for the supervision, adjudication, and control over telecommunications products and services all over the Philippines.
How does a 10K thermistor work?
The enclosed negative temperature coefficient (NTC) thermistor, p/n 1600-10K, works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ‘negative coefficient’). As can be seen be the graph, the resistance of the thermistor drops very quickly.
How accurate is a NTC thermistor?
NTC Thermistors vs. Resistance Temperature Detectors (RTDs)
| Sensor type | Thermistor | RTD |
|---|---|---|
| Accuracy (typical) | 0.05 to 1.5°C | 0.1 to 1°C |
| Long-term stability @ 100°C | 0.2°C/year | 0.05°C/year |
| Linearity | Exponential | Fairly linear |
| Power required | Constant voltage or current | Constant voltage or current |
How is NTC temperature calculated?
NTC (%/°C) × Temperature Tolerance (± °C) = ± % Resistance Tolerance. For example, to determine the resistance tolerance of a Curve 44 thermistor with a ± 0.2 ̊C tolerance at 100 ̊C, -2.93% / ̊C [NTC @ 100C] × (±0.2) [Temperature Tolerance] = ± 0.586 % Resistance Tolerance.
What is the full meaning of NTC?
Negative Temperature Coefficient (NTC) is a condition wherein the resistance, length, or some other characteristic of a material decreases with increasing temperature. 2, The full form of NTC is National Teachers College. It’s used on Academic & Science ,Universities & Institutions in Philippines.
