Can thermistor be used as thermometer?
Some of the most common uses of thermistors are in digital thermometers, in cars to measure oil and coolant temperatures, and in household appliances such as ovens and refrigerators, but they are also found in almost any application that requires heating or cooling protection circuits for safe operation.
How can a thermistor be used to measure temperature?
Using a Thermistor to Measure Temperature. The simplest way of doing this is to use the thermistor as part of a potential divider circuit as shown. A constant supply voltage is applied across the resistor and thermistor series circuit with the output voltage measured from across the thermistor.
How many ohms should a thermistor read?
For example, if the specified resistance at 25°C for a thermistor with 10% tolerance is 10,000 ohms then the measured resistance at that temperature can range from 9,000 ohms to 11000 ohms….Thermistors/Temperature Measurement with NTC Thermistors.

What is the temperature range of a thermistor?
The typical operating temperature range of a thermistor is −55 °C to +150 °C, though some glass-body thermistors have a maximal operating temperature of +300 °C.
Do thermistors go open circuit?
The most common failure mode of a thermistor is an open circuit, as shown in Table 1. This results in inaccurate temperature measurements, thereby causing the thermistor circuit to provide incorrect thermal compensation as it ages.
What is 5d11 NTC thermistor?
5D11 NTC Thermistor. NTC 5d11. 1. Resistance: 5ohms. 2. Diameter: 11mm. An NTC thermistor is a thermally sensitive resistor whose resistance exhibits a large, precise and predictable decrease as the core temperature of the resistor increases over the operating temperature range.
How does a thermistor work?
How a Thermistor Works. Thermistors are variable resistors that change their resistance with temperature. They are classified by the way their resistance responds to temperature changes. In Negative Temperature Coefficient (NTC) thermistors, resistance decreases with an increase in temperature.
What is PT series NTC thermistor?
This is one of the NTC Thermistor types. PT series NTC thermistor has to be connected in series to the power source circuit to avoid the surge current at the instant when the electronic circuits are turned on.
What is the temperature range of the secondary reference series thermistors?
What’s more, the Secondary Reference Series Thermistors are accurate to ± 0.01 °C and cover the temperature range of 0 °C to 100 °C. They come with a NIST-traceable calibration and a resistance-versus-temperature table printed in 0.1 °C increments that can be interpolated to 0.0001 °C.
