An Overview of Thermocouples and Their Applications in India

Thermocouples are critical devices used in various industries for temperature measurement, and their applications in India are vast and diverse. In this article, we will provide an overview of thermocouples and their applications in India.

What are Thermocouples? A thermocouple is a temperature measurement device that consists of two dissimilar metals connected at one end. When the connected end of the thermocouple is exposed to a temperature gradient, a voltage is generated, which can be measured and converted into a temperature reading. Thermocouples are widely used in various industries, including petrochemicals, manufacturing, automotive, aerospace, and more.

Types of Thermocouples There are several types of thermocouples, each with its own unique characteristics, including:

Type K: Type K thermocouples are the most commonly used thermocouples and are suitable for use in high-temperature applications.

Type J: Type J thermocouples are suitable for use in low-temperature applications and offer high accuracy.

Thermocouple Theory - A Complete Concept

A thermocouple is a commonly used type of sensor that is used to measure temperature. Thermocouples are popular in industrial control applications because of their relatively low cost and wide measurement ranges. In particular, thermocouples excel at measuring high temperatures where other common sensor types cannot function. Try operating an integrated circuit (LM35, AD 590, etc.) at 800C.

Thermocouples are fabricated from two electrical conductors made of two different metal alloys. The conductors are typically built into a cable having a heat-resistant sheath, often with an integral shield conductor. At one end of the cable, the two conductors are electrically shorted together by crimping, welding, etc. This end of the thermocouple--the hot junction--is thermally attached to the object to be measured. The other end--the cold junction, sometimes called reference junction--is connected to a measurement system. The objective, of course, is to determine the temperature near the hot junction.

It should be noted that the "hot" junction, which is somewhat of a misnomer, may in fact be at a temperature lower than that of the reference junction if low temperatures are being measured.

Reference Junction Compensation Thermocouples generate an open-circuit voltage, called the Seebeck voltage, that is proportional to the temperature difference between the hot and reference junctions :

Vs = V(Thot-Tref)

Since thermocouple voltage is a function of the temperature difference between junctions, it is necessary to know both voltage and reference junction temperature in order to determine the temperature at the hot junction. Consequently, a thermocouple measurement system must either measure the reference junction temperature or control it to maintain it at a fixed, known temperature.

There is a misconception of how thermocouples operate. The misconception is that the hot junction is the source of the output voltage. This is wrong. The voltage is generated across the length of the wire. Hence, if the entire wire length is at the same temperature no voltage would be generated. If this were not true we connect a resistive load to a uniformly heated thermocouple inside an oven and use additional heat from the resistor to make a perpetual motion machine of the first kind.

The erroneous model also claims that junction voltages are generated at the cold end between the special thermocouple wire and the copper circuit, hence, a cold junction temperature measurement is required. This concept is wrong. The cold -end temperature is the reference point for measuring the temperature difference across the length of the thermocouple circuit.

Most industrial thermocouple measurement systems opt to measure, rather than control, the reference junction temperature. This is due to the fact that it is almost always less expensive to simply add a reference junction sensor to an existing measurement system than to add on a full-blown temperature controller.

Sensoray Smart A/D's measure the thermocouple reference junction temperature by means of a dedicated analog input channel. Dedicating a special channel to this function serves two purposes: no application channels are consumed by the reference junction sensor, and the dedicated channel is automatically pre-configured for this function without requiring host processor support. This special channel is designed for direct connection to the reference junction sensor that is standard on many Sensoray termination boards.

Linearization Within the "useable" temperature range of any thermocouple, there is a proportional relationship between thermocouple voltage and temperature. This relationship, however, is by no means a linear relationship. In fact, most thermocouples are extremely non-linear over their operating ranges. In order to obtain temperature data from a thermocouple, it is necessary to convert the non-linear thermocouple voltage to temperature units. This process is called "linearization."

Several methods are commonly used to linearize thermocouples. At the low-cost end of the solution spectrum, one can restrict thermocouple operating range such that the thermocouple is nearly linear to within the measurement resolution. At the opposite end of the spectrum, special thermocouple interface components (integrated circuits or modules) are available to perform both linearization and reference junction compensation in the analog domain. In general, neither of these methods is well-suited for cost-effective, multipoint data acquisition systems.

In addition to linearizing thermocouples in the analog domain, it is possible to perform such linearizations in the digital domain. This is accomplished by means of either piecewise linear approximations (using look-up tables) or arithmetic approximations, or in some cases a hybrid of these two methods.

The Linearization Process Sensoray's Smart A/D's employ a thermocouple measurement and linearization process that is designed to hold costs to a practical level without sacrificing performance.

First, both the thermocouple and reference junction sensor signals are digitized to obtain thermocouple voltage Vt and reference junction temperature Tref. The thermocouple signal is digitized at a higher rate than the reference junction because it is assumed that the reference junction is relatively stable compared to the hot junction. Reference junction measurements are transparently interleaved between thermocouple measurements without host processor intervention.

An onboard processor then performs linearization and reference junction compensation in the digital domain. Depending on the thermocouple type being used, an appropriate "correction voltage" is computed by mapping reference junction temperature into equivalent thermocouple voltage: Vc=V(Tref). This correction voltage is added to the measured thermocouple voltage to obtain the "corrected" thermocouple voltage:Vtc=Vt+Vc. Finally, the corrected thermocouple voltage is linearized by mapping it into temperature units: T=T(Vtc).

Sensoray Smart Sensor Processors utilize look-up tables for determination of both correction voltage and thermocouple temperature. Although there are many advantages to this approach, the most important is this: high measurement throughputs can be achieved without the need for a high-speed DSP. Consequently, Smart A/D’s offer superior thermocouple measurement performance at a low cost and low power-consumption..

Gravebarr: Yeah I just got this sinking feeling at 1:30 in the morning that something was wrong with the furnace so I went to check on it but my key didn’t work so I just got absolutely no sleep last night because I was so worried that something bad was going to happen. Is this what anxiety feels like? IS THIS WHAT YOU FEEL LIKE EVERY DAY?!

Jonah: Yes.
