How is a thermocouple calibrated?

• A thermocouple is calibrated by adjusting its physical length.

• A thermocouple is calibrated by comparing its voltage output to known temperature references.

• A thermocouple is calibrated by measuring its resistance at different temperatures.

• A thermocouple is calibrated by exposing it to ambient air temperature.

What is the resistance-temperature relationship in thermistors?

• The resistance of NTC thermistors increases with increasing temperature, while PTC thermistors decrease.

• The resistance of thermistors is not affected by temperature at all.

• Both NTC and PTC thermistors have constant resistance regardless of temperature changes.

• The resistance of NTC thermistors decreases with increasing temperature, while the resistance of PTC thermistors increases with increasing temperature.

How do thermocouples compare to other temperature sensors?

• Thermocouples are versatile and durable but less accurate than RTDs and thermistors.

• Thermocouples require frequent calibration to maintain accuracy.

• Thermocouples are only suitable for high-temperature applications.

• Thermocouples are the most accurate temperature sensors available.

What is the working principle of a thermistor?

• A thermistor operates by using a liquid crystal display.

• A thermistor generates heat to measure temperature.

• A thermistor works by changing its resistance with temperature variations.

• A thermistor maintains a constant resistance regardless of temperature.

How does a thermometer work?

• A thermometer uses electrical signals to determine temperature.

• A thermometer measures temperature by using materials that expand or contract with heat.

• A thermometer relies on digital sensors to calculate temperature.

• A thermometer generates heat to measure temperature.

What is the working principle of a thermocouple?

• A thermocouple generates a voltage based on the temperature difference between two junctions of dissimilar metals.

• A thermocouple generates light based on the temperature difference between two metals.

• A thermocouple measures temperature using a liquid-filled sensor.

• A thermocouple operates by heating a gas to measure temperature.
