1.0 - Introduction
TA-25NL / TA-45NL
Temperature Advanced Calibrators TA-25NL and TA-45NL generate temperature
in the insert in order to calibrate thermocouples, RTDs, glass thermometers, thermo-
switches. 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 these types of signal,
including 4-20 mA. Thus, they incorporate the functions of dry block, standard
thermometer and calibrator for RTD, TC and mA, stirred liquid and blackbody source.
TA-45NL calibrator model generates temperatures from -45 ºC to 155 ºC
TA-25NL calibrator model generates temperatures from -25 ºC to 155 ºC.
The calibrator also provides an input for an external probe to perform the
temperature control from a standard sensor (optional) inserted in the same measuring
zone of the sensor to be calibrated, increasing the accuracy and decreasing setpoint
errors and loading effects. The standard sensor calibration curve follows the
parameterization of Callendar-Van Dusen.
They present 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 on a USB connected printer or a PDF document
can be generated.
It has HART®communication (optional) for reading and setting parameters of field
devices that have this protocol.

Another way of performing automatic documented calibrations is by means of
Calibration Software for PC/WindowsTM, which uses USB communication or Ethernet to
connect the computer.
TA Calibrators have also many other features, such as:
RTD input for 2, 3 and 4 wires. Table IEC 60751, JIS or Callendar-Van Dusen
user-configurable. Engineering units configurable to °C, °F and K.
Present inputs for mA, thermocouples and thermo-switches.
Thermo-element reading scaled to ITS-90 or IPTS-68.
Use of internal standard thermometer.
Accuracy to 0.1 ºC, stability of 0.02 ºC and resolution of 0.01ºC.
Carry out completely automatic calibrations without the use of a computer.
Built in Web Server, Ethernet communication and USB serial Communication.
USB port for software/firmware upgrade.
HART®Communication Protocol (optional) with internal resistance configurable,
transmitter power supply and latest DD as option.
The electric signal calibrator is independent from the dry block function.
Display indication when the temperature reaches the desired value.
5.7 inches touchscreen display that eases the operation and configuration of the
calibrator.
Internal regulated 24 Vdc power supply for 2-wire transmitters.
Independent circuit for over-temperature protection and safety.
Insert to choose, soft carrying case, handles and test leads included.

Thermal Fluids suitable for use with the insert (AG)
Low viscosity and safe operating temperature are the most important
characteristics when choosing a heat transfer fluid to produce high homogeneity
in the bath. How less viscous, how better the fluid circulation will be and homogeneous
heat produced in the middle.
We recommend using the following heat transfer fluids for models TA-25NL
and TA-45NL:
Viscosity
Fluid
Flash point*
Usable range
Viscosity
increases
ethyl alcohol
16 °C
-50 °C to 15 °C
Mixture of ethylene glycol
and water (50% of each)
-------------
-30 °C to 90 °C
Water
-------------
5 °C to 90 °C
Silicone oil type 200.05
133 °C
-40 °C to 130 °C
Silicone oil type 200.10
211 °C
-30 °C to 209 °C
*Flash point is the temperature at which a vapor will ignite if exposed to a flame. When the flame is removed, the
vapor stops burning.
At temperatures near the lower end of the range, the thermal fluid becomes very
viscous. It can disturb the circulation and increase the cooling time. Above the upper end,
there is high evaporation of the fluid compromising the stability of the thermal medium.
If you use the insert with stirred liquid it is necessary to insert the magnetic stirrer
(cross shape) at the bottom of the provided insert. The speed of the stirrer is regulated
through the STIRRER option in Calibrator mode. Press STIRRER to turn on and off the
stirrer, and select the speed between Low, Medium and High options in - and +buttons.
A good fit ensures good uniformity for various types of fluids: alcohol (low
temperature), silicone oil (high temperature) etc. Be careful not to accelerate too much
the motor so that the magnetic stirrer stops rotating at the bottom of the insert. This will
worsen the good homogeneity of the calibrator.
To use the insert with the stirred liquid a good practice is to place first the sheath
of the probes or thermometers to be calibrated and then fill up the fluid to a level around
2.5 cm below the top of the insert. This ensures that no overflow occurs either by the
introduction of sensors, or by thermal expansion of the fluid. If the level starts to fall
during use due to evaporation of the fluid, fill up again adding more fluid. Thus the
minimum immersion will not be compromised.
For more accurate measurements use a calibrated probe placed together with the
sensors to be calibrated and connected to the external probe input. The calibrator will
now control the temperature of the block using this temperature as reference (see item
2.1.2 - External Probe Connection). It is also possible to read the indication of this probe
in the RTD Pt-100 auxiliary input.

Black Body Insert (BB)
Placing the insert BB inside the well of the block of the calibrator provides it with a
good black-body cavity with emissivity above 0.95, suitable for calibration of infrared
thermometer.
For more accurate measurements use a calibrated probe placed in the side hole
of the bath and connected to the external probe input. The calibrator will then control the
block temperature using this temperature as a reference. It is also possible to read the
indication of this probe in the Pt-100 RTD auxiliary input.
Align the infrared thermometer to be calibrated with a black body cavity of the
calibrator in a vertical position.
The distance of the thermometer to be calibrated in relation to the bottom
of the blackbody cavity should comply with specification of its technical manual.

2.1.1 - Probe Settings
There are two different references to control 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
control reference comes from a Standard Sensor placed inside the insert, among the
DUT (devices under test). This Standard Sensor, with Callendar-Van Dusen parameters,
eliminates adjustment errors and block loading effects.
It can be used both in control and measurement mode. When used in
measurement mode, the probe indication is displayed on the screen and the control is
made by the internal probe.
Fig. 08 - Choosing the Type of Temperature Reference
To select the Reference between Internal and External, touch the REFERENCE
bar. When selecting External Reference, the Callendar-Van Dusen parameters must be
set. It is also necessary to choose if the External Probe is going to control the block or
not.
ID: Set an identification for the sensor
R0 (): The last resistance measurement in 0 °C of the sensor
A, B, C: Callendar-Van Dusen coefficients
Low (°C): Lower value of the reference sensor calibrated range
High (°C): Higher value of the reference sensor calibrated range
