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.
TI111R/24/ae
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
