Temperature sensors can be divided into three categories: thermopiles, thermistors, and RTDs. The NHQM400B280T5 is an NTC thermistor, meaning it is a negative temperature coefficient (NTC) device that is used as a temperature sensor. This article will discuss the application field and working principle of the NHQM400B280T5.

Application Field of the NHQM400B280T5

The NHQM400B280T5 is a high-performance NTC thermistor designed for temperature sensing applications. It is ideal for use in appliances, HVAC systems, automotive, and industrial temperature control systems. The device features a tight tolerance range of ±2°C, which is ideal for accurate temperature measurement. It also has a high accuracy and stability, making it suitable for use in critical applications.

In addition, the NHQM400B280T5 has a wide operating temperature range of -20°C to +110°C. This makes it suitable for a wide variety of uses, from small appliances to large industrial equipment. It also has a low thermal resistance which allows it to measure temperatures quickly and accurately.

Working Principle of the NHQM400B280T5

The NHQM400B280T5 is an NTC thermistor, which is a temperature sensitive resistor. Its resistance decreases as the ambient temperature increases, and vice versa. The device consists of a ceramic core, which is coated with a metal oxide. The resistance of the device is determined by the composition of the metal oxide. When the ambient temperature changes, the resistance of the thermistor also changes.

In order to use the NHQM400B280T5 as a temperature sensor, it must be connected to an appropriate circuit. The circuit typically consists of a voltage or current source, a measurement device (such as an ammeter or voltmeter), a resistor, and the thermistor itself. When the circuit is energized, the voltage or current flows through the thermistor, causing a change in its resistance. This change in resistance can then be measured using the measurement device and correlated to the ambient temperature.

The NHQM400B280T5 is a highly reliable temperature sensor that is suitable for many applications. Its tight tolerance range and high accuracy makes it ideal for critical temperature measurement applications, while its wide operating temperature range and low thermal resistance make it suitable for use in a variety of devices. The device is easy to install and use, making it an ideal choice for any temperature sensing applications.
