Thermocouple alloys Market - Global Industry Analysis, Size, Share, Growth, Trends and Forecast 2017 – 2025
Thermocouple
consists of two dissimilar metals which are joined to form electrical
junctions at differing temperatures and produce electric current. .
When selecting thermocoupling alloys, it is important to keep in mind
the application temperature range, environment, accuracy required and
length of service. Thermocouples are a widely used type of
temperature sensor. Commercial thermocouples are inexpensive,
interchangeable, are supplied with standard connectors, and can
measure a wide range of temperatures. In contrast to most other
methods of temperature measurement, thermocouples are self-powered
and require no external form of excitation. The main limitation with
thermocouples is accuracy; system errors of less than one degree
Celsius (°C) can be difficult to achieve. Thermocouples are widely
used in science and industry. Applications include temperature
measurement for kilns, gas turbine exhaust, diesel engines, and other
industrial processes. Thermocouples are also used in homes, offices
and businesses as the temperature sensors in thermostats, and also as
flame sensors in safety devices for gas-powered major appliances.
Certain combinations
of alloys have become popular as industry standards. Selection of the
combination is driven by cost, availability, convenience, melting
point, chemical properties, stability, and output. Different types
are best suited for different applications. They are usually selected
on the basis of the temperature range and sensitivity needed.
Thermocouples market is segmented on the basis of product type into K
type, J type, T type, M type, C type, N type, E type, B type, S type,
and R type. Type E, J, K, M, N, and T come under Nickel-alloy
thermocouples, type B, R, and S fall under Platinum/rhodium-alloy
thermocouples, type C, D, and G are under Tungsten/rhenium-alloy
thermocouples, type P falls under Chromel–gold/iron-alloy
thermocouples. Some of the new types of thermocouple are prepared
with the use of alloys such as Chromel – gold/iron alloy
thermocouple, platinum/molybdenum alloy thermocouple and
iridium/rhodium alloy thermocouple. The, thermocouple market is
segmented on the basis of metals used in the sensors into platinum,
nickel, copper, gold, palladium, and tungsten, among others.
Thermocouples market is segmented on the basis of application into
automotive optical, metal manufacturing, industrial applications,
aerospace and defense applications, life science, food and beverages,
consumer utility applications, glass industry applications,
petrochemicals applications, and material processing applications,
among others.
Increasing use of
thermocouples in boilers, temperature controlled rooms and furnaces
is one of the major drivers for this market. Continuous automation in
the industries is driving the demand for the thermocouple alloys and
is expected to be the fastest growing technology. Moreover, the
increasing importance toward safety, quality and security issues and
standards in the production and manufacturing industries is further
aiding the growth of thermocouple alloys market. Thermocouple alloys
market has a lot of constraints like, lack of skilled professionals
and high cost of operation and devices, which are hampering the
growth of thermocouple alloy market.
