Introduction
NTC thermistors are popular temperature sensors composed of a semiconductor material, such as nickel, titanium or aluminum, and a resistor. The thermistor operates according to the principle that the resistance value decreases when temperature increases. The temperature can be calculated from the changes in resistance. The 302FG1K is a special form of NTC thermistor typically used in temperature sensing applications.
302FG1K Temperature Sensor Specifications
The 302FG1K is a glass encapsulated NTC thermistor typically used for sensing temperature in industrial and consumer applications. It provides an output of 10Kohm at 25 °C, decreasing to 5Kohm at 55 °C. The 302FG1K achieves a fast response time with minimal transients, and has a bias voltage of 5V or higher. It features low temperature coefficient of resistance (< 25 °C) and high stability over a wide range of temperatures from -40 to 150 °C. The 302FG1K is a compact, sealed, precision temperature sensor with a wide dynamic temperature range and a wide range of measurement accuracies from 5% to 20%.
What is the 302FG1K Used for?
The 302FG1K is a versatile temperature sensing device used in a variety of applications. It is commonly used in industrial and consumer applications, such as temperature control systems, engine cooling systems, air conditioning and refrigeration systems, and glazing and thermal insulation systems. The 302FG1K can also be used in medical devices, such as patient monitoring, as well as in automotive and marine applications.
Working Principle of the 302FG1K
The 302FG1K temperature sensor is based on the effect of temperature on resistance. It is composed of a semiconductor material and a resistor, so that when the temperature changes, its resistance also changes. The resistance of the 302FG1K is determined by the semiconductor material, which has an exponential relationship with temperature. In other words, the resistance of the 302FG1K changes exponentially with changes in temperature.
Advantages of the 302FG1K
The 302FG1K has many advantages. It is a reliable, accurate, and fast response temperature sensor. It operates over a wide dynamic temperature range and is highly stable over a wide variety of temperatures. It requires only a small bias voltage of 5V or higher and has a low temperature coefficient of resistance. It is also compact and sealed, so it is suitable for use in harsh environments. In addition, the 302FG1K is available in a wide range of accuracies from 5% to 20%, and has excellent measurement accuracy even at very low temperatures.
Conclusion
The 302FG1K is a versatile NTC thermistor used in a variety of applications. It is based on the effect of temperature on resistance and is composed of a semiconductor material and a resistor. The 302FG1K has a wide dynamic temperature range and excellent accuracy, even at very low temperatures. It is compact, sealed, and requires only a small bias voltage of 5V or higher. The 302FG1K is an ideal temperature sensing device for industrial and consumer applications.
