Product Introduction


NTC Temperature Sensor ManufacturingNtc temperature sensor manufacturers
NTC temperature sensor is
NTC thermistor function extension of the assembly, to facilitate the NTC thermistor temperature measurement and installation. In Ya Xun can provide different shapes of the appearance of temperature control probe design and production, very suitable for my company's rapid proofing and small batch production, for your products quickly put into production and testing to provide one-stop service. Start your next project design, learn more NTC temperature sensor information, please contact us immediately to obtain quotes and samples.

What Is The NTC Temperature Sensor
NTC temperature sensor is an NTC thermistor after the wire welding, encapsulate into a different probe and then use an epoxy seal. The NTC temperature sensor retains all the features of the NTC thermistor. After the optimization of the injection and cooling stages, will be made into a complete product, mass production is a continuous cycle of this processing step produced. Molding cycle according to product size, probe material and product design is different, a complete temperature sensor requires several different parts and processes.

Ntc temperature sensor structureNTC temperature sensor works
NTC temperature sensor working principle is the same with the NTC thermistor, the principle is: the resistance value of the resistance with increasing temperature decreases rapidly. It is usually composed of 2 or 3 kinds of metal oxides, and in the high temperature furnace forging into a precision ceramic sintered body. The actual size is very flexible, they can be as small as .010 inches or very small diameter. The maximum size is almost unlimited, but usually applies for half an inch or less.

NTC Temperature Sensor Features
● high sensitivity, fast response
● small size, easy to install
● resistance and B values with high precision, consistency interchangeability
● using double encapsulation process, with good sealing and insulation resistance to mechanical impact, flexural capacity
● Simple and flexible structure, according to the customer set different requirements.
● Wide operating temperature range, the device is suitable for room temperature -55 ℃ ~ 315 ℃, Temperature devices suitable temperature higher than 315 deg.] C (currently can reach 2000 ℃), low temperature can be applied to -273 ℃ ~ -55 ℃;
● easy to use, the resistance value can be arbitrarily selected between 0.1 ~ 100kΩ;
● easy to process into a complex probe shape, can be mass production;
● good stability, strong overload capacity.

NTC Temperature Sensor GlossaryNtc temperature sensor parameters
● R0: resistance of the thermistor at zero power at the specified temperature

● R-T curve: thermistor temperature curve
● Radial curve: the lead of electronic components, it has been introduced from the center line to the edge directed away from the element body. Lead wires parallel to one another to continue outwardly.

● Resistance: characteristic electrical equipment, which obstruct the flow of current.
● Resistance deviation: The additional tolerance due to the slope change compared to the specified nominal resistance temperature curve.
● Resistivity: When the property of the material body is reduced when it is reduced to the standard unit shape, the standard shape is taken as 1 cubic centimeter and the unit of measure is ohm-cm. It is advantageous in predicting the actual resistance of the thermistor at known resistivity and its size.

● Response time: Thermistor indicates the time required for the temperature step to change to the specified number of ranges

Self-heating: the temperature rise due to the power dissipation within the thermistor.
● Slope: The steepness of the resistance temperature curve at the specified temperature range.
Is usually specified for every ° C ohm change or per ° C: [%] (value) change (also known as α).
● Time constant: (T.C.) Thermistor Indicates the time required for the temperature step to change to 63 [%].
● Wattage: Unit of measurement for the consumption or dissipation of electrical components
