Temperature Sensors - NTC Thermistors

NTC Thermistors, also known as Negative Temperature Coefficient, are temperature sensing elements used to measure and control temperature. NTC thermistors are used in a wide range of applications and are known for their accuracy, reliability and low cost. NTC Thermistors are made up of a semiconductor material with varying resistivity. They operate on the principle that the temperature and the resistance between two points of a material have an inverse relationship. When the temperature increases, the overall resistance of the material will decrease and vice versa. The resistance will increase as the temperature decreases. The most common types of NTC thermistors are bead type, disk type and surface mount type. Each has different operating parameters, and each type is best suited for different applications.Bead type thermistors have a bead-like construction, and the resistance of a bead type thermistor is determined by the size and shape of the bead, the material used to make it and the number of layers in the bead. In addition, bead type thermistors have higher insulation resistance and better heat transfer properties than other types of thermistors. These thermistors are commonly used in industrial and consumer temperature sensing applications.Disk type thermistors have a flat disk-like construction, and are typically used in electronic applications such as temperature measurement. Disk type thermistors are typically manufactured from polycrystalline materials such as aluminum oxide, tantalum, and silicon. Surface Mount Type thermistors are designed to be mounted directly onto a printed circuit board. These thermistors are typically used for high accuracy temperature measurements of electronics and components. As the temperature increases, the resistance decreases and vice versa.When selecting an NTC thermistor for a particular application it is important to consider several factors including the temperature range in which the device will be used, the size, shape, type and material of the thermistor.In addition, NTC thermistors can be used in a variety of ways, including as temperature control devices, as temperature sensors, as thermostats, as voltage regulators, and as current regulators. NTC thermistors are also used in medical devices, automotive applications, industrial process control and instrumentation, and home automation applications.NTC thermistors are suitable for a wide range of temperatures and they can be used in many applications. They are reliable, accurate and cost-effective. They are an ideal choice for temperature sensing and control applications.
