THERMISTOR BASICS – Wavelength Electronics

In addition to thermistors, several other types of temperature sensors are used. The most common are Resistance Temperature Detectors (RTD) and integrated circuits (IC), such as the LM335 and AD590 types. Which sensor works best for a particular use is based on many factors. The table below gives a brief comparison of the benefits and drawbacks of each.

Introduction to Temperature Sensors: Thermistors ...

· Instead of using a thermistor along with a fixedvalue resistor in a voltage divider circuit, an alternative solution would be an analog lowvoltage temperature sensor, such as the TMP36 from Analog Devices. In contrast to a thermistor, this analog IC provides an output voltage that is almost linear; the slope is 10mV/°C over a temperature range of 40 to +125°C, and it’s accurate to ±2 ...

Thermistor RepRap

· A thermistor is usually more accurate than a thermocouple, but thermocouples can handle higher temperatures and are linear. A thermocouple gives a really small voltage (Type K produces 200C) that can be calibrated and conditioned by an IC (AD595A Amplifier, MAX6675 SPI, or MAX31855 SPI) into a form readable by the electronics ...

Thermistor | Analog Devices

Thermistors are a type of semiconductor, meaning they have greater resistance than conducting materials, but lower resistance than insulating materials. The relationship between a thermistor’s temperature and its resistance is highly dependent upon the materials from which it’s made and is referred to as the temperature coefficient. It is composed of materials with known resistance and ...
