1.WHY CHOOSE WISDOM HIGH QUALITY THERMOCOUPLE ALLOYS?
All our raw material is made from prime material, not recycle material. We have more than *5 years experience in manufacturing thermocouple alloys.
In the market, not all the Thermocouple alloys are with standard chemical composition and stable EMF. Professional and reliable is the soul of our business.
2.DESCRIPTION OF THERMOCOUPLE ALLOYS:
A thermocouple is a temperature measuring device consisting
of two conductors of dissimilar metals or alloys that are connected
only at the ends. When the ends are at different temperatures a
small voltage is produced in the wire that can be related directly
to the temperature difference between the ends. If the temperature
at one end is known, the temperature at the other end can be
determined.
Thermocouple wire or extension grade wire is recommended to
be used to connect thermocouples to the sensing or control
instrumentation. The conditions of measurement determine the type
of thermocouple wire and insulation to be used. Temperature range,
environment, insulation requirements, response, and service life
should be considered.

4.MAIN CHARACTERISTICS OF WISDOM THERMOCOUPLE ALLOYS
TYPE J (Iron vs Constantan) is used in vacuum, oxidizing,
inert or reducing atmospheres. Iron element oxidizes rapidly at
temperatures exceeding **8'C, and therefore heavier gauge wire is
recommended for longer life at these temperatures.
TYPE K (CHROMEL vs ALUMEL ) is used in oxidizing, inert or
dry reducing atmospheres. Exposure to vacuum limited to short time
periods. Must be protected from sulfurous and marginally oxidizing
atmospheres. Reliable and accurate at high
temperatures.
TYPE T (Copper vs Constantan) is used or service in
oxidizing, inert or reducing atmospheres or in vacuum. It is highly
resistant to corrosion from atmospheric moisture and condensation
and exhibits high stability at low temperatures. It is the only
type with limits of error guaranteed for cryogenic
temperatures.
TYPE E (CHROMEL vs Constantan) may be used in oxidizing,
inert or dry reducing atmospheres, or for short periods of time
under vacuum. Must be protected from sulfurous and marginally
oxidizingatmospheres. Produces the highest EMF per degree o any
standardized thermocouple.
Type N thermocouple (Ni Cr Si-Ni Si Mg) is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. The main chemical composition of positive leg Nicrosil(NP) is Ni: Cr: Si≈*4.4: *4.2: 1.4; negative leg Nisil (NN) is Ni: Si: Mg≈*5.5: 4.4: 0.1. Type N thermocouple also be used in the similar atmospheres that type K works, and the operating temperature range is ***0~***0 °C.
