What are NTC thermistors used for?
NTC thermistors are used as ICLs (inrush current limiters) to protect circuits of electrical and electronic devices against inrush currents easily and effectively.
What are thermistor resistors used for?
Thermistors are temperature-dependent resistors, changing resistance with changes in temperature. They are very sensitive and react to very small changes in temperature. They are best used when a specific temperature needs to be maintained, and when monitoring temperatures within 50°C of ambient.
What are five major uses of thermistors?
Uses of Thermistors
- Digital thermometers (thermostats)
- Automotive applications (to measure oil and coolant temperatures in cars & trucks)
- Household appliances (like microwaves, fridges, and ovens)
- Circuit protection (i.e. surge protection)
- Rechargeable batteries (ensure the correct battery temperature is maintained)
Where are NTC thermistors used in cars?
The car industry You will now find them as components in fuelling systems, safety, engine monitoring and cooling. This has been especially key with changes to emissions regulations in modern cars.
What is NTC thermistor?
An NTC thermistor is a temperature sensor that uses the resistance properties of ceramic/metal composites to measure the temperature. Our full spectrum NTC sensors offer many advantages in temperature sensing including miniature size, excellent long-term stability, high accuracy and precision.
When to use NTC thermistor probes and why its necessary?
With NTC thermistors, resistance decreases as temperature rises usually due to an increase in conduction electrons bumped up by thermal agitation from valency band. An NTC is commonly used as a temperature sensor, or in series with a circuit as an inrush current limiter.
How to measure temperature using a NTC thermistor?
– R1 = resistance at the lowest temperature (T1 = -40°C). – R2 = resistance at a middle temperature (T2 = 25°C). – R3 = resistance at the highest temperature (T3 = 125°C).
What is the difference of NTC sensor and lm35?
Temperature sensors directly connected to microprocessor input and thus capable of direct and reliable communication with microprocessors. The sensor unit can communicate effectively with low-cost processors without the need for A/D converters. An example of a temperature sensor is LM35. The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius temperature.
