Technical Information
Thermocouples TH51, TH52 & TH56
General purpose MgO insulated thermocouples with connection
head, extension lead wires or connectors for process and laboratory
applications
Areas of application
Magnesium Oxide insulated thermocouples,
commonly referred to as MgO thermocouples, are
used in many process and laboratory applications.
They have many desirable characteristics making
thermocouples a good choice for general and special
purpose applications.
The sensors can be used on:
• Heat exchangers
• Power & recovery areas
• Furnaces
•Dryers
• Flue gas
• Compressor stations
• Process reactors
• Metallurgical and Glass manufacturing
Head transmitters
Instead of directly wiring your temperature sensors to
your control system, use transmitters to reduce
wiring and maintenance costs while increasing
measurement accuracy.
Your benefits
• One source shopping for temperature measurement
solutions. World class transmitter with integrated sensor
offering.
– Remove and install straight out of the box!
• Improved galvanic isolation on most devices (2 kV)
• Simplified model structure: Competitively priced, offers
great value. Easy to order and reorder. A single model
number includes sensor and transmitter assembly for a
complete point solution.
• All iTEMP®transmitters provide long term
stability ≤0.05 % per year

Function and system design
Measuring principle The thermocouple sensing element consists of two metal wires that are homogeneous but different from each
other and insulated along their entire length. The two wires are welded together at one end, known as "hot
junction". The other end, where the wires are free, is known as "cold junction" and is connected to an
electromotive force measurement circuit where the force is generated by the different thermoelectric power of
each of the thermocouple wires if there is a temperature difference between the hot junction and the cold
junction (Seebeck effect). The function that links the electromotive force to the temperatures difference is a
curve whose characteristics depend on the materials used in the construction of the thermocouple. The
thermocouples comply with the temperature-electromotive force (EMF) tables of ASTM E-230 and IEC60584
standards.
Measuring system
Example of an application of the temperature assemblies
RIA 261 Field display
The display measures an analog measurement signal and indicates this on the display. The display is connected
in a 4 to 20 mA current loop and also derives its supply from the loop. The volt drop is almost negligible
(< 2.5 V). The dynamic internal resistance (load) makes sure that independently from the loop current, the
maximum volt drop is never exceeded. The analog signal at the input is digitalized, analyzed, and shown in
the rear illuminated display. For details see Technical Information (see "Documentation").
RNS 221
The RNS 221S power supply (24 V DC, 30 mA) has two galvanically isolated outputs for supplying voltage to
loop powered transmitters. The two channel power supply has a wide-range input for main power, 20 to
250 V DC/AC, 50/60 Hz to be used in any electrical circuit. For details see Technical Information (see
"Documentation").
RNS 221 is an UL recognized component to UL-3111-1.

Equipment architecture MgO thermocouple assemblies consists of a thermocouple element swaged in hard-packed standard purity
(96%) Magnesium Oxide mineral insulation and encased in a metal sheath. Thermocouple sheaths have been
fully annealed; they can be formed into many configurations, and can be bent into a radius of twice the size of
its outer sheath. The hot junction of the thermocouple types according to ASTM E-230 specification are welded
to form a pure joint to ensure highest accuracy and long term stability.

Measurement range Measuring range by type and size
!Note!
These values are valid for single and duplex thermocouples. The temperature limits given are intended only as
a guide to the user and should not be taken as absolute values or as guarantees of satisfactory life or
performance. These types and sizes are sometimes used at temperatures above the given limits, but usually at
the expense of stability or life or both. In other instances, it may be necessary to reduce the above limits in
order to achieve adequate service.
!Note!
Duplex versions (2 elements) of Type N with 1/16", 3/16" and 3/8" sheath diameter are not available.
Thermocouples with 316 SS sheath are rated for a maximum temperature of 1700 °F (927 °C).

Thermocouple assemblies with iTEMP®transmitters are an installation ready solution to improve the
functionality of temperature measurement by increasing accuracy and reliability when compared to direct
wired sensors. Overall installation costs are lower than with direct wired sensors, since an inexpensive pair of
signal (4 to 20 mA) wires can be run over long distances.

These values for insulation resistance apply also between each thermocouple wire at single and duplex

Galvanic isolation Galvanic isolation of Endress+Hauser iTEMP®transmitters (input/output)
In applications where fast response time is needed, grounded thermocouples are recommended. This
thermocouple design may cause a ground loop. This can be avoided by using iTEMP transmitters with high
galvanic isolation.

!Note!
The calculation was done for pipes only, for MgO insulated thermocouples the values might be higher. In any
case for different lengths, other materials, variation in sheath diameter or wall thicknesses, stress analysis is
recommended. Failures are caused by forces imposed by static pressure, steady state flow, and vibration.

Hot or measuring junction Grounded junction
Grounded junction
The thermocouple junction is welded securely into the closure end of the sheath, becoming an integral part of
the weld. This is a good general purpose, low cost junction providing faster response times than an un-
grounded junction of similar sheath diameter. Grounded junctions should not be used with Type T
thermocouples, due to the copper wire. For a reliable temperature reading of grounded thermocouples
Transmitters with galvanic isolation are strongly recommended. iTEMP transmitters have galvanic isolation of
min. 2kV (from the sensor input to the output and the housing).
Ungrounded junction
Ungrounded junction
The welded thermocouple junction is fully isolated from the welded closed end sheath. This junction provides
electrical isolation to reduce problems associated with electrical interference. Ungrounded junctions are also
recommended for use in extreme positive or negative temperatures, rapid thermal cycling and for ultimate
corrosion resistance of the sheath alloy. iTEMP transmitters have an excellent noise immunity (EMC) meeting
all requirements listed under IEC61326 for use in noisy environments.
!Note!
Dual ungrounded elements supplied with individually isolated junctions, except Ø 1/16" which are supplied
with common junctions.
