NTC thermistors for temperature measurement

Contacts and housing used for assembly with the thermistor must be clean before mounting. Ensure that adjacent materials are designed for operation at temperatures comparable to the surface temperature of the thermistor. Be sure that surrounding parts and materials can withstand the temperature. Avoid contamination of the thermistor surface during processing. The connections of sensors …

Air Conditioner Temperature Thermostat Sensor Problems ...

When the sensor isn’t working correctly, it may cycle on and off randomly between proper activation periods. This means if your home is too hot or too cold, the thermostat may switch on or off before the proper temperature is met or when the inside can be too cold or warm inside. The main indicator of a failing or faulty sensor is erratic cycles.

Thermistors/Temperature Measurement with NTC Thermistors

From the figure you can see that thermistors have high sensitivity. A small change in temperature causes a large change in resistance. Also note that the response of this thermistor is not linear. That is, the change in resistance for a given change in temperature is not constant over the thermistor''s temperature range. Figure 2: Thermistor temperatureresistance curve 40°C to 60°C The ...

What is a Thermistor Inrush Current Limiters

What is a Thermistor. A thermistor is a thermally sensitive resistor that exhibits a precise and predictable change in resistance proportional to small changes in body temperature. How much its resistance will change is dependent upon its unique composition. Thermistors are part of a larger group of passive components.

THERMISTOR BASICS – Wavelength Electronics

Temperature Range: The approximate overall range of temperatures in which a sensor type can be used. Within a given temperature range, some sensors work better than others. Relative Cost: Relative cost as these sensors are compared to one another. For example, thermistors are inexpensive in relation to RTDs, partly because the material of choice for RTDs is platinum.
