Semiconductor Based Temperature Sensors

At combination of a motor protection PTC thermistor with a switching device one receives an effective, well-priced and quickly reacting solution for the protection of electrical machines from overheating. As visible in fig. 1, the resistance value of the PTC thermistor increases steeply after reaching of its reference temperature. For the classification of the sensor one fixes a point in the ...

Temperature Sensors: Positive Temperature Coefficient (PTC ...

· While we are trying to limit the current through a device to reduce self-heating, a PTC fuse utilises self-heating to limit current due to the increase in resistance as the temperature climbs. NTC thermistors are by far the most popular in circuits in the wild. Most integrated circuits that have connections for a thermistor will only support an NTC thermistor, such as battery charger circuits ...

THERMISTOR BASICS – Wavelength Electronics

The thermistor attached to the device reacted quickly to the change in thermal load and recorded accurate temperatures. The remote thermistor also reacted but not quite as quickly. More importantly, the readings are off by a little more than half a degree. This difference can be very significant when accurate temperatures are required. Figure 6: Thermistor Location Response Graph. Once the ...

Using Custom Thermistors with the Temp-to ... - Analog Devices

Users of thermistors must determine temperature from a measured resistance with help from the thermistor vendor. The Temp-to-Bits family includes built-in coefficients for many common thermistors including the popular 44004/44033 Ω, 44006/44031 10kΩ, and 44008/44032 30kΩ devices. Using one of these standard types is the simplest way to make thermistor temperature measurements. …
