Temperature Sensors - NTC ThermistorsNTCLE400E3472H is an NTC thermistor of two-terminal negative temperature coefficient (NTC) device. It is mainly used for temperature measurement, temperature control and temperature compensation in industrial applications.Temperature measurement and control with thermistors requires precise knowledge of the thermal characteristics of the device and system. The NTCLE400E3472H thermistor is designed to provide an accurate and precise response to temperature changes. It has a low temperature drift coefficient, allowing it to measure accurately even when exposed to extreme temperatures.The NTCLE400E3472H thermistor allows the user to measure the temperature in a wide range of temperatures, with a low temperature-driven hysteresis. This is beneficial when the temperature must be monitored over time, or in a changing environment. The thermistor is also able to compensate for bias errors caused by temperature variation, providing a more consistent reading over a longer period of time.Working PrincipleNTCLE400E3472H has an NTC thermistor. It is a ‘negative temperature coefficient’ device that has a resistive element that changes its resistance in response to changes in temperature. The main principle behind the operation of a thermistor is that its resistance decreases with temperature. When the device’s temperature rises, its resistance decreases, and the current flowing through it increases. Conversely, when the temperature drops, the resistance increases, and the current flowing through it decreases. This change in resistance is proportional to the change in temperature, allowing the device to be accurately used for temperature measurement.The NTCLE400E3472H also relies on the thermistor’s hysteresis property. Hysteresis is a phenomenon in which the same current is produced by different temperatures. This means that the device’s resistance at a certain temperature is always lower than the resistance at a lower temperature. This property of the thermistor offers a very stable temperature measurement in changing environments.Application FieldNTCLE400E3472H has a wide range of application fields. It is commonly used in industrial processes, such as in HVAC systems, medical devices, energy systems, refrigeration, electronics, electrical engineering and automotive applications. In HVAC systems, the thermistor can be used to measure temperature and humidity in the system, and control the temperature of the air conditioning system. In medical devices, the thermistor can be used to measure and control body temperature in healthcare products such as medical monitoring equipment. In electronics, the thermistor is often used to measure temperature for safety functions. It can also be used in temperature compensation circuits to adjust element characteristics according to the temperature variation. In electrical engineering, the thermistor can be used to detect and monitor abnormal temperatures in electrical systems. In automotive applications, the thermistor is used to measure engine temperature and transmission temperature. It can also be used in vehicle controllers and battery-operated devices to provide temperature compensation. ConclusionThe NTCLE400E3472H thermistor is an NTC device that is designed to provide an accurate and precise response to temperature changes. It has a low temperature drift coefficient, allowing it to measure accurately even when exposed to extreme temperatures. It also has a hysteresis property, which allows it to provide a more stable temperature measurement in changing environments. The NTCLE400E3472H thermistor has a wide range of application fields, including HVAC systems, medical devices, energy systems, electronics, electrical engineering and automotive applications.
