A thermistor is a temperature measuring device which acts like a temperature sensitive resistor. It is an active device that requires a current flow to measure its resistance so that the temperature may be calculated and/or displayed.
A thermocouple is a device composed of two dissimilar metals fused together. An electrical potential occurs across the junction of the metals. As the potential is influenced by the temperature of the metal junction the output voltage can be measured and calibrated to show the temperature at the joint.
Both devices may be employed to measure the temperature within a fixed space, or on a probe to measure the temperature at a remote point or points.

Difference between sensor and Acatuars?
A sensor is a device that is programmed to send a signal as soon as a specified event occurs; for example the motion sensor in supermarket doors. Meanwhile, an actuator is a device that does an especifc action according to a signal received. Lets go back to the door: Once the motion sensor detects a movements, it send a signal to a piston that moves the door. To sum up: sensors detect events and actuators perform an action
How is thermal overload protection done in stator windings of motor?
one way is to use RTD sensor put inside the motor windings. The RTD sensor is connected to an electronic thermal overload relay. This type of relay can provide running temperature of the motor, on the electronic thermal over load relay display panel. RTD sensor is a wire wound resistor that changes resistance depending on the temperature
What is the difference of ntc sensor and lm35?
NTC is negative temp coefficient transducer,working with resistor while lm 35 is an IC type transducer
What is an analog sensor?
An analog sensor is a device that measures an analog quality (such as temperature, wind speed, sound frequency or velocity). Many of us fail to recognize the difference between qualitative and quantitative measurements. Quantitative descriptors are actually just the result of counting something; seventeen marbles, five folding chairs, three apples... Qualitative descriptors are the result of estimating something; eight cups of sliced apples, a five pound bag of marbles, the current room temperature. When we use a scale to measure something, it's called "qualitative"... or analog. Converters are available that allow a computer to achieve a close approximation of an analog measurement, but for the computer to use the value it must first be converted to a digital signal. Inside the computer, that digital signal is all ones and zeroes, but many of them can be put together to represent a very large number. If that doesn't help, perhaps a basic physics class or even a computer "digital logic" class might be beneficial.
What is a delta pressure sensor?
It is a slang tern given to a Differential Pressure Sensor or Transducer.
Is a oxygen sensor a thermistor sensor?
No, an oxygen sensor is not a thermistor sensor. An oxygen sensor measures the amount of oxygen in the exhaust gases of a vehicle to help determine the air-fuel ratio. A thermistor sensor, on the other hand, is a type of temperature sensor that relies on the change in resistance with temperature to measure temperature.
What Is The Difference Between Thermister And Sensistor?
A thermistor is a type of resistor whose resistance changes with temperature, typically used for temperature sensing. A sensistor is a sensor that measures changes in electrical properties in response to changes in environmental conditions, not specifically limited to temperature sensing. In summary, a thermistor is a specific type of sensor, while a sensistor is a broader term for various types of sensors.
What is a ntc thermistor?
A NTC thermistor is a temperature sensor that has a "negative temperature coefficient". That means as temperature goes up, the resistance of the device goes down over it's operating range.
What does fault code ff16 mean?
Apparently this is an air thermistor fault - an error with the air temperature sensor...
How do you locate iat sensor on Subaru Forester?
It's often a thermistor (temperature sensitive resistor) located inside the MAF sensor housing.
What is the difference between pressure sensor and temp sensor?
One monitors pressure and the other monitors temperature.
How does a digital thermometer measure temperature if mercury is not present in it?
A digital thermometer measures temperature using a sensor (such as a thermistor or infrared sensor) that detects changes in electrical resistance or infrared radiation as temperature changes. This information is then converted into a digital readout on the display of the thermometer. Mercury is not required in digital thermometers as they rely on electronic sensors instead.
How is a thermistor used in a baby incubator?
A thermistor in a baby incubator is used to monitor and regulate the temperature inside the incubator. It measures the temperature and sends feedback to the incubator's control system, which then adjusts the heating elements to maintain a stable and optimal temperature for the baby. This helps prevent fluctuations in temperature and ensures a comfortable and safe environment for the baby.
What is a air temp sensor?
IAT air intake sensor is a thermistor ( a resistor that varies the value of it's resistance in accordance with temperature changes ) the change in the resistance values will directly effect the voltage signal from the sensor to the PCM/ECM. As the sensor temperature increases, the resistance values will decrease. As the sensor temperature decreases the resistance values will increase.
What is the difference between thrust and force?
In rocket test bench, how to measure the temperature. Where is the temperature sensor place in rocket test bench.
What is the difference between thermostat and thermister?
A thermostat is a device that maintains a set temperature by turning a heating or cooling system on or off, while a thermistor is a type of resistor whose resistance changes with temperature. Thermistors are used in thermostats to sense temperature changes and trigger the system to adjust accordingly.
What is the difference between the temperature sensor and temperature sender on a 1993 Chevy blazer?
temp sensor - sends signals to the computer for driveability temp sender - measures temp and sends to gauge in dash
