The primary differences between the two thermocouples are: Measuring Range... Type K = -330°F to +2460°F (-200°C to +1250°C) Type J = -40°F to +1382°F (-40°C to +750°C) Sensitivity... Type K = approximately 41 µV/°C Type J = approximately 55 µV/°C If you already own a gauge it is important that you use the correct thermocouple sensor type, otherwise the result will be incorrect CHT temperature readings due to mismatched sensitivities.

A thermocouple is made up of of two dissimilar conductors in contact with one another, which produce a voltage when heated.  Thermocouples are used as temperature sensors for measurement and control and can also be used to convert a temperature gradient into electricity. The  Type K thermocouple  (chromel -alumel) is the most commonly used general purpose thermocouple.  It is inexpensive and a wide variety of probes are available in its −200 °C to +1350 °C / -330 °F to +2460 °F range.  Sensitivity is approximately 41 µV/°C.   Wire color standard is yellow (+) and red (-).

Thermocouple heads  provide the means for making connection between thermocouple  and extension wire, and protect the connection against corrosion, abrasion and breakage caused by handling.  Thermocouple heads  are easy to install and are convenient for checking purposes.

A time constant has been defined as the time required by a sensor to reach 63.2% of a step change in temperature under a specified set of conditions. Five time constants are required for the sensor to stabilize at 600 of the step change value. Exposed junction thermocouples are the fastest responding. Also, the smaller the probe sheath diameter, the faster the response, but the maximum temperature may be lower. Be aware, however, that sometimes the probe sheath cannot withstand the full temperature range of the thermocouple type.

Sheathed thermocouple probes are available with one of three junction types: grounded, ungrounded or exposed. At the tip of a grounded junction probe, the thermocouple wires are physically attached to the inside of the probe wall. This results in good heat transfer from the outside, through the probe wall to the thermocouple junction. In an underground probe, the thermocouple junction is detached from the probe wall. Response time is slowed down from the grounded style, but the ungrounded offers electrical isolation of 1.5 M1/2 at 500 Vdc in all diameters. The thermocouple in the exposed junction style protrudes out of the tip of the sheath and is exposed to the surrounding environment. This type offers the best response time, but is limited in use to noncorrosive and nonpressurized applications. Please contact: thermocouplesupplier@gmail.com

Thermocouples are available in different combinations of metals or calibrations. The four most common calibrations are J, K, T and E. Each calibration has a different temperature range and environment, although the maximum temperature varies with the diameter of the wire used in the thermocouple. How do I choose a thermocouple type? Because thermocouples measure in wide temperature ranges and can be relatively rugged,they are very often used in industry. The following criteria are used in selecting a thermocouple:Temperature range Chemical resistance of the thermocouple or sheath material Abrasion and vibration resistance Installation requirements (may need to be compatible with existing equipment; existing holes may determine probe diameter).

The continuous thermocouple is one of a class of devices which detect and respond to heat. Other devices in this class include the line-type heat detector and heat-sensitive cable. The basic construction of all these devices consists of two or more strands of wire separated by insulation within a long, thin cable. Whilst they sense temperature, they do not in fact provide an output measurement of temperature. Their function is to respond to abnormal temperature rises and thus prevent fires, equipment damage, etc. The advantages of continuous thermocouples become more apparent if the problems with other types of heat detector are considered. The insulation in the line-type heat detector and heat-sensitive cable consists of a plastic or ceramic material with a negative temperature coefficient (i.e. the resistance falls as the temperature rises). An alarm signal can be generated when the measured resistance falls below a certain level. Alternatively, in some instruments, the insul

What is MI cable? M.I. (Mineral Insulated) cable is used to insulate thermocouple wires from one another and from the metal sheath that surrounds them. MI Cable has two (or four when duplex) thermocouple wires running down the middle of the tube. The tube is then filled with magnesium oxide powder and compacted to ensure the wires are properly insulated and separated. MI cable helps to protect the thermocouple wire from corrosion and electrical interference. Features： Fireproof: Our MI cable can withstand very high temperatures (higher than 1000°C), since all its components are inorganic. It can go on working during a fire, maintaining power to all emergency services, allowing all safety and protection measures within the building to be activated. Waterproof:  The mineral insulated metallic sheath and special IP67 waterproof fittings prevent the penetration of water, and dust towards the cores. The Mineral insulated cables are also suitable for outdoor applications or for insta

Temperature plays a critical role in nearly every industrial operation throughout the process industries. In some highly sensitive processes, a change in temperature of as little as 1–2% can result not only in the loss of hundreds of thousands of dollars but also in the creation of a potentially dangerous situation. That’s why knowing which temperature measuring device to use for an application is so important. Temperature Sensors --Figure 1. Options include dual, 3-wire RTD (top); single, 4-wire RTD (center); and Type K thermocouple (bottom). Temperature Sensors Resistance temperature detectors (RTDs) and thermocouples are the most commonly used sensor types in the process industry today. Each operates on different physical principles and offers distinct advantages and disadvantages when it comes to meeting requirements for accuracy, repeatability, stability and cost. Neither device is inherently superior to the other. RTDs operate on the principle of thermal resistivity. As te

The error in measring temperature with thermocouples with any instruments is related sveral fators that combine together to affect the overall accuracy of the measurment: 1.Thermocople wire error:this is the error resulting from the fact that a given sample of thermocouple wire will not exactly meet the temperature versus millivolt realtionship given the standard tables.The most accurate designation is for Type T thermocouple.The errors allowed for T type over the range -40 to 130℃ are 1.0 for standard wire and 0.5℃ for speical limits of error wire. 2.Reference junction error:this is the error in determing the temperature of the reference junction. Sometimes called “cold junction”. 3.Voltage measurment error: this is error in the measurement of the small voltage produced by the temperature difference between the measuing junction and the reference junction. 4.Linearization error: the temperature vs.millivolt realtionship for thermocouples is inherently non-linerar.The accuracy o

There are 5 possibilities if the thermocouple doesn’t work stable: 1. Bad contact forTerminal and thermal electrode: Solution:clean the Terminal and thermal electrode,retighten. 2. Insulation fails,which may bring intermittent short circuit and ground connection. Solution:Find the fault point.Repair the insulation. 3. Intermittence of the thermode or measuring therminal. Solution:If the break point is on the measuring therminal,the break point should be welded ,or change the thermocouple. 4. insufficient installation or external vibration. Solution:Anti-detonation measures to install the thermocouple firmly. 5. External disturbance: Solution:Examine the interference source. Contact: thermocouplesupplier@gmail.com

The conventional thermocouple is used with an outer protecting tube or thermowell to protect it from aggressive and corrosive process condition. This improves longevity of the thermocouple. However, response time is poor. To overcome above problem, We  has designed MI Thickwall Thermocouple having thicker wall with relatively larger conductor diameters. This construction enables the user to insert the thermocouple directly in the process without a protecting tube or thermowell, improving response time considerably.

The most basic thermocouple construction is the wire type consisting of two dissimilar metals homogeneously joined at one end to form the measuring junction. All wire-type thermocouples have an exposed junction. While wire-type thermocouples offer good response time, ruggedness, and high temperature use, they are susceptible to environmental conditions and therefore must be protected. Mineral insulated thermocouples overcome the disadvantages of wire type construction by imbedding the thermocouple wires in ceramic insulation and protecting them with a metallic sheath. The mineral insulated cable (MI cable) design is based on small mass and high thermal conductivity which in turn promotes rapid heat transfer from the heat source to the measuring junction.The sheaths are impervious to most liquids and gases and withstand high external pressures. The seamless design protects against moisture or other contaminants attacking the thermocouple elements. Since the only materials used to make

There are many different types of temperature sensors. We will deal with the two most common types, thermocouples and RTDs.Not because they are the most common, but because these two are the only two types Smart Sensors makes. How do Thermocouples  work? In 1821 Thomas Seebeck, while making a pot of tea, discovered that when two dissimilar metals are joined together, a current flows, as long as the temperature at one of the junctions is at a higher temperature than the other junction. Little did he know, as he finished his tea, that he would be famous for discovering the current that flowed in this circuit and the EMF (Electro Motive Force) that produced this current would be forever called the Seebeck Effect. Seebeck circuit showing the positive (kp) and negative (kn) of a Chromel Alumel thermocouple. If the temperatures (T1 and T2) are different at the two junctions a current will flow in the circuit. Seebeck was responsible for developing the most rugged and simplistic ye

Mineral insulated cables have an outer sheath of metal with 2 to 8 inner conductors. The insulation material is made from a highly compressed metal-oxide powder (preferably MgO or Al2O3). Mineral insulated thermocouple cables have inner conductors of thermocouple base material. Mineral insulated cables for RTDs have inner conductors of copper, copper-nickel alloys, nickel, nickel-chromium or nickel-plated copper. Mineral insulated cables are designed for high-temperature applications and are used wherever there are particularly strict requirements with regard to mechanical, chemical and electrical stability. On account of their good flexibility, the use of mineral insulated cables is preferred in areas where mounting is difficult and where a high degree of flexibility is required (for example, laboratories or pilot manufacturing plants).The minimum bending radius is 3 times the outer diameter of the mineral insulated cable. Innovations in technology and manufacturing have made it po
