Introduction

The MF51E103F3950 is a temperature sensor based on NTC (Negative Temperature Coefficient) thermistors. It has a wide range of applications in many industries and is optimal for harsh environments. In this article, we will discuss its application field and working principle.

Application Field

The NTC thermistor temperature sensors are used where precise temperature measurement and control are required. They are used in various sectors such as industrial electronics, appliances, food processing, and automotive industry. The MF51E103F3950 is an especially suitable NTC thermistor because it is designed for harsh environments such as extreme temperatures, vibrations, and electrical fields. This device is applicable for thermally compensated temperature measurements, along with other appliance control applications. It is cost-effective and extremely reliable. The MF51E103F3950 is also used in heating and cooling systems. They can be used to detect the temperature of the cooling or heating liquid or air. It helps to maintain the temperature of the environment at the desired level and prevents undue heating or cooling. It is often used to measure the temperature of an exhaust system. The thermistor can also be used in medical applications, as it is highly accurate in monitoring patient’s body temperature. It can even detect the internal temperature of the patient and help to provide value information to the healthcare provider. Finally, the MF51E103F3950 is mainly employed in industrial equipment to measure the temperature of the core and ensure accurate operation. It can also be used for other temperature related applications in the industry.

Working Principle

The working principle of the MF51E103F3950 temperature sensor is based on the NTC (Negative Temperature Coefficient) thermistors. As the name suggests, the electrical resistance of an NTC thermistor decreases when the temperature increases. The resistance change is highly temperature dependent, and is utilized to measure the temperature with high accuracy. In the MF51E103F3950 sensor, a nickel-alloy resistive element is replaced with a temperature sensitive NTC block. This NTC block is encased in an insulating thermoplastic material to protect it from external factors such as dust, water, and vibration. The device consists of two pins which are used to measure the resistance of the NTC block and calculate the corresponding temperature value. The voltage applied to the NTC block should be regulated to avoid any damage to the thermistor due to excessive heat or current. The thermistor is attached to a printed circuit board. An electrical power source is connected to the input pin of the printed circuit board. This power source is also connected to the NTC block which produces a voltage drop across its terminals. This voltage drop is proportional to the resistance of the NTC block and its corresponding temperature. The voltage drop across the NTC block is then measured by the printed circuit board. The signal is then amplified and converted into a corresponding temperature value.

Conclusion

The MF51E103F3950 is a temperature sensitive NTC thermistor and is highly reliable due to its wide temperature range and rigorous durability. Its application field includes industrial electronics, heating and cooling systems, medical solutions, and other industrial temperatures control applications. The working principle of the thermistor is simple and based on the principle that the electrical resistance of an NTC thermistor decreases with increasing temperature. The temperature is calculated by measuring the voltage drop across the terminals of the NTC block and then converting it into a temperature value.
