Temperature Sensors - NTC Thermistors

Temperature sensors play an important role in the field of control and instrumentation. One such temperature sensing devices is known as NTC thermistors. It is a temperature sensitive resistors that can detect changes in temperatures and hence be used to measure temperatures. A USP11492 is one such type of NTC thermistor and in this article, we will explore its application field and working principle. NTC thermistors are composed of two elements: an insulator that acts as a resistor and a semiconductor that serve as a temperature coefficient. Essentially, when a current runs through them, they modify their resistivity according to the temperature. NTC thermistors offer a wide operational temperature range and high accuracy, making them suitable for applications where precision and stability are paramount.The USP11492 is one of the latest in the line of NTC thermistors and it has the longest resistance range available on the market. It is designed to precisely detect variations in temperature for a wide variety of applications. It features high accuracy and has a resistance range of 0.5K to 10K ohm. The USP11492 is typically used to detect temperatures from -20°C to 125°C, with an operating temperature range of -40°C to 150°C, making it suitable for industrial and consumer applications.The USP11492 has diverse applications in various industries such as automotive, HVAC, and medical. Its main advantage is that it offers a high precision and repeatability in measuring temperatures.In terms of its working principle, USP11492 operates on the basic concept that the resistance of the thermistor changes proportionally to the temperature. This change in the resistance according to the temperature is known as the thermistor characteristic. The USP11492′s resistance will increase as the temperature increases for it is a Negative Temperature Coefficient (NTC) thermistor. This behavior is explained by the fact that the molecules in the material of the thermistor vibrate more rapidly in higher temperatures, reducing the resistance in the material. The thermistor can be connected to the system in two different ways. It can be connected in series with the circuit to detect the temperature without altering the circuit or it can be connected in parallel with the circuit to control the flow of current based on the temperature.At the end of the day, USP11492 is a reliable and accurate NTC thermistor with a wide range of applications across multiple industries. The thermistor has a resistance range of 0.5K to 10K ohm and can detect temperatures from -20°C to 125°C, with an operating temperature range of -40°C to 150°C. It is designed to measure temperatures with high precision and repeatability and can be configured to detect temperatures without altering the circuit or to control the flow of current based on the temperature.
