1 - Introduction
TA-1200PLAB
The TA-1200PLAB Calibration Furnace is state-of-the-art in the manufacture and
performance of high temperature furnaces for calibration of thermocouples.
Its design privileges fundamental technical characteristics in temperature
measurement and which are usually the predominant sources of uncertainty in a
calibration. Thus it has been designed and tested according to international standards to
perfect the following characteristics:
I. Low axial and radial gradients due to the use of differentiated heaters distributed
along the thermal well in order to minimize losses at the ends of the insert and to
extend the temperature constant region called the measurement zone.
II. High immersion of the sensors to be compared - it has an insert with 250 mm of
immersion in the conductive part and about 70 mm in the insulation part, making
about 320 mm of total immersion of the sensors, which minimizes heat losses by
conduction the rod.
III. High thermal stability or thermal inertia - The 400 mm long insert has a large mass
volume and stabilizes any temperature fluctuation due to insertion or removal ofthe
sensor in the insert.
The entire calibrator is enclosed in a thermal shield for operator and laboratory
protection from the high temperatures generated. Thus in an eventual blackout of energy
the cooling of the furnace happens naturally and surely.
Temperature Advanced Calibrator TA-1200PLAB generates temperature in the
insert in order to calibrate thermocouples. Besides providing high accuracy temperature
values, it also allows the measurement of signals generated by the thermo-element which
is being calibrated. This is possible due to an embedded calibrator specific for this type of
signal. Thus, they incorporate the functions of dry block, standard thermometer and
calibrator for TC.

•TA-1200PLAB calibrator model generates temperatures from 50 ºC (122 ºF) to
1200 ºC (2192 ºF).
•Presents 02 inputs for thermocouples that can follow the parameterization of ITS90
or standard tables.
•Carries out completely automatic calibrations with or without the use of a computer.
•Accuracy to ± 2.5 ºC, stability of 0.01 ºC and resolution of 0.01 ºC.
The calibrator provides an input for an external probe to perform the temperature
measurement from a standard sensor (optional) inserted in the same measuring zone of
the sensor to be calibrated. The standard sensor calibration curve follows the
parameterization of ITS-90.
It presents a wide variety of programming resources, allowing the performance of
automatic calibrations. In this case, the sensor is placed in the insert and its electrical
terminals are connected to the embedded calibrator. The operator defines the calibration
points and the number of repetitions (task), then the process is started and all the
sequence is automatically accomplished. After completing the task, a Calibration Report
is issued and it can be printed directly in a USB connected printer or can be generated as
a PDF document.
TA-1200PLAB has also many other features, such as:
•Built in Web Server, Ethernet communication.
•USB port for software/firmware upgrade.
•The electric signal calibrator is independent from the dry block function.
•Display indication when the temperature reaches the desired value.
•5.7 inches touch screen display that eases the operation and configuration of the
calibrator.
•Thermocouple reading scaled to ITS-90 or IPTS-68.
•Independent circuit for over-temperature protection and safety.
•Insert to choose and test leads included.

1.4 - Initial Usage
Identify if the following parts are present:
•TA-1200PLAB Calibrator;
•Metallic or ceramic insert;
•Bottom insulation of the insert (only one central hole);
•Top insulation of the insert (same holes of the metallic insert);
In the core of the dry block TA-1200PLAB there is a ceramic tube. Therefore, for
safety purposes, the insert and the insulators are separated. A support is sent to protect
the block. Remove the screws indicated by the arrows and remove the support. Store it
and use it whenever you need to transport the dry block.
Finish the mounting using the grounding pin board and the frame with a grid.
1.4.1 - Mounting the Insert in the Calibrator - Vertical Model
To mount the insert inside the Calibrator, proceed as follows:
I) Place the Calibrator in its definitive place and spacing more than 25 cm from nearby
walls.
II) Observe in the following figure the type of gap in the lower part ofthe metallic insert
with the type offittingin the grounding pin inside the furnace well. Note: The ceramic
insert does not have this gap.
Fig. 02 - Insert Background (Horizontal Model)
I) Screw or fix the extractor to the insert and holding the insert with both hands slowly
insert the heavy insert into the very fragile ceramic well. Orient yourself by the mark
of a point on the insert to keep this side up.
II) It is essential to ensure an effective grounding if the gap coincides with its fitting on
the grounding pin. It is necessary to repeat the movement of the insert back and
forth a few times in the well to hear the click noise between the insert and the
grounding pin. Unscrew the extractor.
III) Then insert the top insulation in line with the holes in the insert. Use a ceramic rod
for it.
IV) Finally, tighten the metal cap by aligning it with the other holes in the top of the
calibrator well.
Note that the sensors to be tested must pass through the insulation and deepen
inside the metal insert to obtain a correct temperature measurement.

2.1.1 - Probe Reference
There are two different references to the thermal block: Internal Reference and
External Reference.
The Internal Reference is a sensor built into the block.
The External Reference is an option for more accurate measurements. The
reference comes from a Standard Thermocouple Sensor placed inside the insert, among
the DUT (devices under test). This Standard Sensor should be a noble metal thermocouple
(R, S, B or Au-Pt types). To increase accuracy to the measurements, ITS-90 parameters
can be used to correctthe thermocouple electromotive force in reference to the IEC-60751
table.
presys

PRESYS │ Instruments TA-1200PLAB
Page 11
The configuration of the thermocouple calibration coefficients (C0, C1, C2 e C3
corrects the electromotive force (E) given by the linearization table of the thermocouple by
the IEC-60751 standard. After correction, the electromotive force of the thermocouple
follows this formula:
E’ = E + C0 + C1.t + C2.t² + C3.t³, where t is the temperature in °C and E’ and E the
electromotive force in mV.
When using External reference, the probe indication is displayed on the screen and
the control is made by the internal probe.
