Applications:Widely used in internal or external wiring requiring high heat-resistance or high speed transfer circuit.
Conductors can also be provided with stranded wire, dimensions such as 0.2mm*7, 0.3mm*7, 0.2mm*19.Ohmalloy aslo can make all kinds of insulation resistance wire on customer’s special requirement.
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.
