NTC thermistors are temperature sensing devices that are very commonly used in a variety of applications. The SM105V3K is a professional NTC thermistor widely used for temperature measurement and control. It has a wide range of practically achievable accuracies and is suitable for a variety of systems requiring precise temperature control. This article will discuss the applications of the SM105V3K and its working principle.

Applications

The SM105V3K is one of the most widely used NTC thermistors due to its wide range of temperature sensing capabilities. The thermistor is specifically designed to measure temperatures ranging from -50 to +150℃ with an accuracy of ±3% or ±1℃. It is mostly used in medical, mechanical, electrical, and communication systems for precise temperature control and monitoring. It is especially useful for measuring the temperature of liquids, such as motor oil, and other substances. The thermistor is also used in air-conditioning systems, heating systems, and refrigeration systems, as well as in ovens and furnaces. The SM105V3K is also used for temperature sensing in automotive and industrial applications.

The SM105V3K can also be used in various other applications, such as scientific research, quality control, process control, and chemical work. It has a wide range of applications in both industrial and consumer-based settings, making it a versatile choice for a variety of temperature sensing requirements. The thermistor is also widely used in temperature-sensitive products such as medical thermometers, space heaters, and food thermometers.

Working Principle

The SM105V3K uses a semiconductor material, such as lead or gallium arsenide, that is sensitive to temperature changes. When the temperature of the material increases, its electrical resistance decreases. The SM105V3K uses this change in resistance to measure temperature. The thermistor has a negative temperature coefficient (NTC), which means that it has a lowered resistance when the temperature increases.

The thermistor contains a resistor and a semiconductor material, which form the sensing element. The resistor is connected to a power source, while the semiconductor material is connected to the output. As the temperature changes, the resistance of the thermistor changes, and this change is detected by the output. The output is then used to calculate the temperature.

The thermistor also contains a capsule made of ceramic and metal alloy that insulates the sensing elements from outside environmental influences. This ensures that the thermistor readings remain accurate and unaffected by outside stimuli, such as dust, humidity, and other factors.

The SM105V3K is a versatile and reliable temperature sensing device that is used in a variety of applications. Its wide range of temperature sensing capabilities and accurate readings make it an ideal choice for precise temperature control and monitoring. The thermistor makes it easy to measure temperatures of liquids, air, and other substances.
