PTFE / PVC / Rubber Insulated RTD / Pt100 Resistance Cable With 3
Cores or 4 Cores
A thermocouple is composed of two wires made from dissimilar
metals. These two wires are joined to form a temperature
measurement junction. Each wire is made of a specific metal or
metal alloy. For example, the positive (+) conductor of a type K
thermocouple is made of a chromium/nickel alloy called chromel and
the negative (-) conductor is made of an aluminum/nickel alloy
called alumel. Wire used to make a thermocouple junction is called
thermocouple wire.

Thermocouple types
Industry specifications recognize different types of thermocouples
and thermocouple wires with a letter designating each type. Some
common types are K, J, T and E. Different thermocouple types have
different temperature ranges over which they can be used
successfully. The chemical make-up of each thermocouple alloy, the
temperature error limits allowed, and the color codes for each
thermocouple type are specified in ISA/ANSI standard MC96.1. The
important thing to remember from an application standpoint is that
the thermocouple wire type must match the thermocouple type.
Extension Wire
Thermocouple extension wire types such as KX, JX, TX and EX are
used to connect the measuring junction to the temperature recording
or process control instrumentation. This can be hundreds or even
thousands of feet away. Extension wire is normally exposed to
temperatures and other environmental conditions that are less
extreme than those encountered by the measuring junction. As a
result, "extension" grade wire is not calibrated above 400° F (204°
C) and is typically insulated and jacketed with materials with
lower temperature ratings. Since low voltage instrumentation
signals are being carried thermocouple extension wire is often
shielded.

Resistance Temperature Detectors (RTDs)
There are other temperature measurement technologies than the
thermocouple such as RTDs (resistance temperature detector). In
applications with temperatures above 1,200° F (650° C) thermocouple
is used. At lower temperatures RTDs are used for their simpler
operation and greater sensitivity and stability. Thermocouples have
a better response time. RTDs are special resistors whose resistance
value changes with temperature in a known way. RTDs are connected
to the temperature recording or process control instrumentation
using ordinary copper instrumentation cable. Thermocouple wire is
not required to connect an RTD.
Typical RTD cable is standard instrumentation cable in two, three,
or four conductors or possibly groups of pairs/triads/quads
depending on the type of RTD being used and number of devices being
monitored. Individual or overall shielding is often used for noise
immunity.
