Thermocouple Types: Type J, Type K, Type N, Type T, Type E, Type R, Type S, Type B, Type C. A thermocouple consists of a welded 'hot' junction between two dissimilar metals - usually wires - and a reference junction at the opposite end. The metal alloys chosen as thermocouple positive and negative leg wires define the type of thermocouple ...
TYPE J THERMOCOUPLE (Iron/Constantan) Composed of a positive leg which is iron and a negative leg which is approximately 45 % nickel-55% copper. (Note - Constantan is Copper-Nickel.) When protected by compacted mineral insulation and appropriate outer sheath, Type J is useable from 0 to 816°C, (32 to 1500°F). It is not susceptible to aging in the 371 to 538°C, (700 to 1000°F) temperature range. A drift rate of 1 to 2°C, (2 to 4°F) occurs with Type …
J-type thermocouples. These are another widely used variety, although they will generally have a narrower temperature range (-40 to +750 Celsius) than K-types, and exhibit a shorter overall lifespan if regularly exposed to more excessive heat. The positive leg of a type-J unit is made from iron wire, and the negative leg will be composed of a copper-nickel (constantan) alloy. It’s one of the ...
Thermocouples are used as temperature sensors for measurement and control and can also be used to convert a temperature gradient into electricity. The J Type thermocouple (iron–constantan) is a common, general purpose thermocouple with a termperature range of approximately −40 to +750 °C, and sensitivity of 55 µV/°C. Wire color standard is white (+) and red (-). Request Info Hidden ...
Thermocouple Types. Pairing different kinds of metals give us a variety of measuring ranges. These are called “thermocouple types” and we know several of them: Thermocouple Type K: which pairs chrome and alumni, resulting in a wide measuring range of −200 °C to +1350 °C (−330 °F to +2460 °F). Thermocouple type J; Thermocouple type T
· The type J thermocouple is having iron as their positive legs which constantan as negative legs. These types of thermocouples are very usable in oxidizing, vacuum, inert, and reducing atmospheres. These thermocouples must be taken care of due to iron leg because it may get oxidized or rusted and hence special care is required for its operation. The temperature range of these types …
Type J - Copper vs Copper-Nickel, IEC 60584-1 Thermocouple Type J, commonly referred to as Iron/Constantan, this is one of the few thermocouples that can be used safely in reducing atmospheresHowever, in oxidising atmospheres above 550°C, degradation is rapid. Maximum continuous operating temperature is around 800°C, although for short term use, temperatures up to 1,000°C can …
Purchase cost-effective and accurate type j thermocouple range at These easy-to-read type j thermocouple range record humidity without interference.
Thermocouples consist of two dissimilar metal wires joined at a hot junction; as temperature changes, a millivolt signal is generated. ProSense type J and type K bolt-on ring sensors are ideal for nozzles, extruder barrels, die heads, molds and other surface sensing applications. Measuring ranges are available from 32 to 900 degrees F.
· The comparison of Thermocouple types includes the following. For J-Type. Composition: It has Iron (+) and Constantan (-) legs. Temperature Range: The temperature range of J-Type ranges from –210 to +1200 °C. Accuracy: The accuracy for J-type is Typical: +/- (or) +/- .75% particular error limits: +/- (or) %
Type K will generally outlast Type J because the JP wire rapidly oxidizes, especially at higher temperatures. Temperature Range: •Thermocouple grade wire, −454° to 2,300°F (−270 to 1,260°C) •Extension grade wire, −32° to 392°F (0 to 200°C) •Melting …
The J type thermocouple has a generally more stable measurement range than the K-type thermocouple, since the temperatures it handles are generally medium. J type Thermocouple. The following J-type thermocouple chart shows across the temperature ranges that the spectrum of industrial applications that can be coupled to use handles.

A J type thermocouple range falls between these two extremes. As mentioned above, it can read temperatures from 0 to 750°C, and this is due to its composition of iron and constantan. The Curie point of iron is 770°C, at which point the magnetic field of the iron wire begins to change its behavior, causing any voltage readings to be unreliable. Even though the structure of the thermocouple ...
All of the refractory types of thermocouples are having temperature ranges from 32 till 4200 degrees Fahrenheit. The main usages of such thermocouples are mainly in the vacuum furnaces which are having temperature ranges beyond the temperature capacity of platinum.
