NTC sensor

One kind of thermistor whose resistance drops with temperature is the NTC (Negative Temperature Coefficient) sensor. Because of their sensitivity and precision, these sensors are frequently employed for temperature monitoring and control. The ceramic materials used to make NTC thermistors show a noticeable decrease in electrical resistance as temperature rises. An NTC sensor's temperature and resistance have a non-linear connection, making them extremely sensitive to even little temperature fluctuations. NTC sensors are widely utilized in many different applications, including as consumer electronics, medical equipment, HVAC (heating, ventilation, and air conditioning), and automotive systems. Their cost-effectiveness, longevity, and dependability make them a well-liked option for temperature sensor systems.

The three main components of a NTC sensor are:

1. Thermistor Material : A ceramic or polymer substance is usually used here, and its resistance drops with temperature. Zinc, manganese, nickel, cobalt, and copper oxides are examples of common materials.
2. Encapsulation : This guards against external elements including moisture, mechanical strain, and chemical contamination that might harm the thermistor material. Glass, epoxy, or plastic are examples of encapsulation materials.
3. Leads or Terminals : These provide the electrical connection between the external circuitry and the thermistor. Usually, they are constructed from metal strips or wires that are welded or soldered to the thermistor material.
