Temperature Sensors - NTC Thermistors
Temperature sensors are important devices that measure temperature and then output an electrical signal as a function of temperature. The most widely used types of temperature sensors are thermocouples, resistance temperature detectors (RTD\'s), thermistors, and semiconductor-based sensors.

NTC Thermistors are one of the most commonly used type of temperature sensors today. An NTC thermistor is an electronic component that has a resistance to electric current that varies with temperature. This temperature-dependent resistance is due to the semiconductor nature of the material used to create the thermistor, typically manufactured from metal oxides such as nickel, copper, or manganese.

The most commonly available and easily used thermistor is the GS502F1K. The nominal resistance at 25°C (77°F) is 502 ohms. This type of thermistor is often used as a temperature sensor in automatic control systems because of its precise temperature coefficient and excellent temperature stability over a larger range. Its range is from −40° to +105°C (-40° to 221°F).

As a fundamental principle, the resistance of an NTC thermistor changes in a predictable manner when it is heated or cooled. When the temperature is reduced, the resistance increases; when it is heated, the resistance decreases. This resistance variation follows a “cold curve” which is a graph of the resistance vs. temperature. For the GS502F1K the cold curve is shown as follows:

By adjusting the circuit around the thermistor, the resistance can be monitored and an electrical current adjusted as the temperature changes. This current can then be used as an input to a device such as a controller, displaying the temperature as an analogue or digital signal. This enables the temperature of a process to be monitored and controlled reliably and accurately.

The most common use of the GS502F1K thermistor is in thermometer devices designed for temperature measurement and control. It is also typically implemented in temperature-sensitive consumer and industrial products such as ovens, refrigerators, and air conditioners. The GS502F1K can be used in a wide range of industrial applications including automotive engine control, environmental monitoring, and other thermostatic control circuits.

The GS502F1K thermistor is an excellent temperature sensor option for a broad range of applications. Its temperature coefficient and excellent temperature stability over a larger range make it an ideal fit for temperature measurement and control. The adaptability of the GS502F1K thermistor allows it to be used in various industries such as automotive, HVAC, and electronics.
