NTC Thermistors as Temperature Sensors | Projects | Altium

· NTC Thermistor Implementation: Voltage Divider. The most straightforward way we can measure the temperature is with a voltage divider. You can use the thermistor as either the top or the bottom leg of the potential divider. If you use the thermistor as the “top” leg of the potential divider, the voltage will increase as the temperature increases. If you use a thermistor as the bottom leg of the …

Thermistor Applications Sensors and Transducers

A thermistor is a type of temperature sensor. They are very small, relatively cheap and give a very quick response to temperature change. Thermistors consist of a small bead resistor and two wires which can be connected to an electrical circuit, a change in temperature will mean there is a change in resistance in the resistor which can be detected and measured by the electrical output of the ...

THERMISTOR BASICS – Wavelength Electronics

The voltage limits of the sensor feedback to a temperature controller are specified by the manufacturer. The ideal is to select a thermistor and bias current combination that produces a voltage inside the range allowed by the temperature controller. Voltage is related to resistance by Ohm’s Law. This equation is used to determine what bias current is needed. Ohm’s Law states that the ...

This Should Work: Thermistor Senses Liquid Levels. by John Wynne Download PDF In precision temperature measurement applications using thermistors, RTDs, or other resistive temperature sensors, care must be taken to avoid errors due to selfheating of the sensor by the excitation current. In some applications, however, the selfheating effect can be put to good use.

Temperature Sensing with Thermistors

a resistive component will produce a voltage drop across that component, thermistors require an external excitation in order to operate. An easy and costeffective way to bias thermistors is to use a constant voltage source and a voltage divider circuit, as shown in Figure 2. As the temperature changes, you will see a change in the voltage drop (V

· I’m using the more precise % tolerance 1K ohm PTC thermistor with the voltage follower as it’s designed for temperature sensing applications, and the 470 ohm option we are testing is intended for current limiting applications. The 470 ohm thermistor would not make a lot of sense to connect to a circuit that will provide a more accurate sensing result, as it’s tolerance is so large.
