What is the most commonly used thermistor type?

NTC thermistors
NTC thermistors are the most commonly used (especially the 10KΩ NTC thermistor) and along with an addition series resistor, RS can be used as part of a simple potential divider circuit. Thus changes to its resistance due to changes in temperature, produces a temperature-related output voltage.

Where are thermistors used in cars?

Most vehicles have their thermistors on the front of the car, located behind the grill. This location makes the instrument’s measurements sensitive to reradiated heat from the road surface.

Which type of thermistor is used for instrumentation?

Negative Temperature Coefficient (NTC) NTC thermistors are the most common type available for use. The defining characteristic of this thermistor is that its resistance decreases as temperature increases.

What are thermistors automotive?

Thermistors are widely used as inrush current limiters, temperature sensors (negative temperature coefficient or NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements (positive temperature coefficient or PTC type typically).

What are the advantages limitation and applications of thermistor?

Accuracy is limited, in most applications, only by the readout devices. Thermistors are non-linear devices over a temperature range, although now units with better than 0.2\% linearity over the 0-100°C temperature range are available. The typical sensitivity of a thermistor is approximately 3 mV/°C at 200°C.

What is thermistor in instrumentation and control?

Thermistors are devices made of metal oxide semi-conductor material which either increase in resistance with increasing temperature (a positive temperature coefficient) or decrease in resistance with increasing temperature (a negative temperature coefficient).

Can a smartphone be used as a thermometer?

Smart Thermometer This app uses the temperature sensors of a smartphone to show the temperature on the phone. Smart Thermometer app also offers an upgrade package that adds charts with historical data of the smartphone along with the phone’s readings and better widgets.

Where are PTC thermistors used?

Ceramic PTC thermistors are used instead of conventional fuses to protect loads such as motors, transformers, etc. or electronic circuits against overcurrent. They not only respond to inadmissibly high currents but also if a preset temperature limit is exceeded.

What is an application for a PTC thermistor device?

One application for PTC thermistors is overcurrent protection. Overcurrent protection reacts when a fault condition occurs. When this condition happens, the thermistor will heat up. The higher heat will cause it to switch from a low to a high resistance.
