NTC sensor applications
NTC thermistors have a wide range of applications. The medical industry relies on NTC thermistors in a variety of applications including catheters, dialysis equipment and patient monitoring. Many household appliances, including dryers and coffee makers, use NTC thermistors to accurately measure temperature. In the area of building controls and processes, HVAC and refrigeration equipment use NTC sensors to measure temperature to increase efficiency and control. The automotive and aerospace industries use NTC thermistors for test, measurement, and production applications.

Introduction to NTC Sensors
NTC temperature sensor definition:
NTCサーミスタ, プローブ, cable assembly (set). A finished thermistor assembly that is composed of a thermistor shell, extension leads, and sometimes a connector.
structure
Generally composed of NTC thermistor, プローブ (metal shell or plastic shell, 等), extension lead, and metal terminal or connector

Principle of NTC sensor
Using NTC thermistor, under a certain measurement power, the resistance value decreases rapidly as the temperature rises. Utilizing this characteristic, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, thereby achieving the purpose of detecting and controlling temperature.

Applications of NTC Sensors
● On air conditioners, 冷蔵庫, 冷凍庫, 給湯器, ウォーターサーバー, heaters, 食器洗い機, 消毒キャビネット, 洗濯機, dryers and other home appliances.
● Automotive air conditioners, water temperature sensors, intake air temperature sensors, engines
● Switching power supply, UPS uninterruptible power supply, frequency converter, electric boiler, 等.
● Smart toilets, 電気毛布, 等.
特徴:
● High sensitivity and fast response speed
● Resistance and B values have high precision and good consistency and interchangeability
● Adopting double-layer encapsulation process, it has good insulation and sealing properties and resistance to mechanical collision and bending.
● The structure is simple and flexible, and can be customized according to different design requirements of customers.

NTC temperature sensor terminology explanation
R0: The resistance of the thermistor at zero power at the specified temperature
R-T curve thermistor and thermometer or graph
Radial curve: The lead of an electronic component, which leads out of the component body in a straight line from the center to the edge. The leads continue outward parallel to each other.
Ratio, 0 に 50: The number (ratio) obtained by dividing the thermistor’s resistance at 0°C by its resistance at 50°C. It can be expressed as a slope and facilitates comparison.
抵抗: The property of an electrical device that resists the flow of electrical current.
Resistance deviation: The additional tolerance due to changes in slope compared to the specified nominal resistance temperature curve. Added to the 25°C tolerance, a chart is provided for this.
Resistivity: The property of a material’s volume resistance when reduced to a standard unit shape, which is taken to be 1 cubic centimeter and measured in ohm-centimeter. It facilitates prediction of the actual resistance of the thermistor given known resistivity and its dimensions.
応答時間: The time it takes for the thermistor to indicate a temperature step change to a specified range.
Self-heating: The thermistor’s own temperature rises due to power dissipation within the thermistor.
Slope: The steepness of a resistor’s temperature curve over a specified temperature range. Usually specified as ohms per °C change or [%] (value) change per °C (also known as α).
Thermistor: (Thermistor) A temperature-sensitive ceramic resistor.
Time Constant: (T.C.) The time required for the thermistor to indicate a temperature step change of 63 [%].
Wattage: A unit of measurement of power consumed or dissipated by an electrical component
