Thermistors Construction of Thermistor Resistance vs. Temperature Curve of Thermistor Difference between Thermistors and Resistance Temperature Detectors (RTD) Resistance V/s Temperature Characteristic Curve Thermistor as Temperature Sensor Thermistor Types To know about various types of thermistors, it is essential to know the linear relationship between temperature, & resistance.This linear relationship is shown as dR = …
Thermocouple A thermocouple is made up of two metal conductors of different metals that have been soldered together at the ends to form an electrical circuit. The Seebeck effect causes a voltage to be created when there is a temperature differential between the two joints, and when one of the two joints are opened, there …
Thermocouples A thermocouple is a junction made of two distinct metals that generates a voltage in response to a change in temperature. Thermocouples are a form of temperature sensor that is frequently used for measurement and control, as well as for converting heat into electric power. Thermoelectric effect Three effects of Thermocouple 1. The …

What is Thermowell? 1.Thermowell Insertion length. U > R In above example the total probe length is 6.5 inches but the insertion length is 4 inches. 2.Thermowell Immersion length For example, some vendors specify the sensitive length of the sensor say RTD is 40mm, but they recommend immersion length must be 60 mm for liquid …
Temperature measurement and control is an important factor in all process industries and in power plants environments of higher temperature and higher pressure. The thermowell allows the temperature sensor Thermocouple and RTD to remove easily from the process environment for the purpose of calibration in case of measurement error, or replacement in case of …
What is temperature? We can define temperature as the degree of hotness and coldness of an object or an environment. We can also determine the kinetic energy of a matter by the temperature measurement. It is a scalar quantity that would help us to determine the direction of heat flow between two objects. Temperature is …

What is a thermistor? A thermistor is a device that would change its resistance with temperature, its name has derived from words such as a thermal resistor. This device is a thermally sensitive resistor that would change its resistance for a change in temperature. Basically, thermistors are semiconductors that behaves like a resistor. These devices …
What is a thermocouple? Thermocouples are devices that are used to do temperature measurements. One of the major advantages of this device is that it can be used for a wide range of temperature measurements, we can use this device to measure zero degrees to thousand degrees Celsius. Thermocouples are widely used in many industrial …
