Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors that have a negative temperature coefficient (NTC). This means that the resistance of the thermistor decreases as the sensing temperature increases. The GS105W1K thermistor is a widely used NTC thermistor designed for temperature sensing and control in a variety of environments.

Application Field

The GS105W1K is a suitable solution for temperature sensing and control in a variety of environments. It is suitable for applications such as temperature compensation of circuits, environmental monitoring, medical care equipment, thermostat control, and protection devices. It is also capable of monitoring temperatures over a wide range, from -25 to 150 degrees Celsius, with accuracy of the temperature measurement being within 0.5 degrees Celsius at room temperature.

Working Principle

Thermistors are semiconductor devices that change their electrical resistance in response to changes in temperature. The resistance in a thermistor is dependent on its material composition. The GS105W1K thermistor is made of a special alloy material that has a negative temperature coefficient, meaning that its resistance will decrease as the sensing temperature increases. This variation in resistance can be used to calculate the temperature of an object or environment.

The most common way of measuring temperatures with the GS105W1K thermistor is to connect it in a voltage divider configuration, with a fixed resistor, as per figure 1. The output voltage of this configuration is then proportional to the temperature; the higher the temperature, the lower the output voltage.

This type of temperature measurement system is usually calibrated with a temperature reference source to ensure the accuracy of the system. The GS105W1K thermistor can also be used in combination with additional component such as diodes, amplifiers and processors to provide more accurate temperature measurements.

Conclusion

The GS105W1K thermistor is a reliable and widely used temperature sensor. It is suitable for a variety of applications and provides accurate temperature measurements over a wide temperature range. By connecting it in a voltage divider configuration with a fixed resistor, or in combination with additional components such as diodes, amplifiers and processors, it can provide temperature measurements with great precision.
