4.2 Description
Model TC59-E eTEFRACTO-PAD
to measure the temperature of tubes typically located within cokers, furnaces, heat
exchangers and reactors. This model of thermocouple is used within industrial
high-temperature and/or corrosive environments where temperature measurement is
critical.
The most important considerations for effective tubeskin design are repeatability,
durability and accuracy. To achieve these functions the thermocouple must incorporate
within its design excellent insulation properties, material compatibility and good physical
contact with the tube. It must also have the ability to withstand high radiant temperatures
and stresses, and in some cases harsh combustion chemistry.
With all tubeskin designs the correct installation is of prime importance. Incorrect
attachment can ultimately lead to inaccurate temperature readings.
Sheathed cable
The sheathed cable (mineral-insulated cable, MIMS cable) is flexible. The minimum
bending radius is 5 times the sheath diameter.
TC59-E can be assembled as cable probes or as sensors with a connection head.
Optionally, a temperature transmitter can be built into the connection head. For this
temperature transmitter, separate operating instructions will be enclosed.
