Introduction
AST IR-CAST 2C are specially designed highly accurate digital two-color rectangular measuring field IR
pyrometers for non-contact temperature measurement specially used in foundries for molten metal.
2.1 Application, Range and Working Principle
The digital AST IR-CAST 2C pyrometer use ratio method in which 2 adjacent wave lengths are used for
measurement of temperature. They are suitable for high temperature measurement ranging from 700°C to 1700°C.
AST IR-CAST 2C pyrometers are suitable for industrial purpose due to following advantages:
ŸThe pyrometer gives accurate reading even when metal stream moves with in rectangular area.
ŸMeasurement of temperature is not affected by emissivity of object.
ŸMeasurement of object temperature is possible where dust, moisture & other contaminants are present in
surrounding environment.
ŸThe measuring object can be smaller than spot size.
ŸThe pyrometer can be switched between 1-colour & 2-colour mode.
These pyrometers have solid body in stainless steel housing which provides high operation safety even in rough
industrial environment, and large variety of optics with fixed focus which can be easily used in all industrial areas.
AST IR-CAST 2C has a fast response time of 20msec. Pyrometer have RS-232, RS-485 & USB 2.0 outputs.
Response time, emissivity, sub range and peak picker selection can be preset ex works or adjusted through available
software.
The pyrometer temperature measurement method utilizes the fact that objects emit thermal radiation in an
amount that directly corresponds to their own temperature and surface emissivity. Two color pyrometer involves
measuring thermal radiance at two different wavelengths and inferring the temperature from the ratio of these
spectral radiances. Radiance ratio thermometers can be significantly more accurate than single band thermometers
in many applications.
The application in which AST pyrometer can be used is:
Ÿ Molten Metal
If the target is within this rectangular area, it gives an accurate temperature reading even when liquid moves within
this area.

has to be measured. This heat radiation is passes through the lens to the sensor and is then converted
to an electrical signal. The farther the measured object is from the pyrometer, the larger the area that will be
measured by the pyrometer. Depending on customer need, the pyrometer is designed with fixed optics.
The pyrometer measure temperature by receiving heat radiation from the object whose temperature
Some fixed optics focus is as below:-
For Installed spot size calculation.
If the pyrometer is not installed at manufactured working distance (WD) then spot size at actual installed
distance should be calculated.

For Installed spot size calculation, horizontal & vertical spot size should be calculated separately by putting the
parameters from the fixed optics table.
(A) Vertical Spot Size Calculation
CAST 2C(700° - 1700°C) then spot size is 30mm (as given in table). If user installed this pyrometer at 5000mm then
spot size is not 150mm (as given in table), user should have to calculate as given method.
Installed spot size at 5000mm = (5000/1000) x (6 + 4) - 4 = 46mm
for example, if factory made working distance is 1000mm & pyrometer is AST IR-
(B) Horizontal Spot Size Calculation
IR-CAST 2C(700° - 1700°C) then spot size is 6mm (as given in table). If user installed this pyrometer at 5000mm then
spot size is not 30mm (as given in table), user should have to calculate as given method..
Installed spot size at 5000mm = (5000/1000) x (30 + 4) - 4 = 166mm
Final spot size should be

Installation of the Pyrometer
3.1 Installation
3.1.1 Location selection
Qualified operating personnel should do the installation. Location should be good enough so that pyrometer
should get continuous infrared radiation.
Pyrometer distance from object is according to below points:-
1.
2. Know your pyrometer spot size according to point 2.3.
3. Pyrometer ambient temperature should be within 0° to 70°C (read 3.1.4).
3.1.2 Correct Positioning of the pyrometer
With through the lens sighting (TL)
In case of through the lens sighting a reticule rectangle marks the position of the measuring area. This
rectangle is true-sided and parallax-free.
Note: The reticule rectangle (TL) is only for indication of measuring area, not exactly shows the measuring
area.
3.1.3 Mounting of pyrometer
To install the pyrometer at the place of measurement a mounting support is supplied as an accessory, after
losing the clamp screws, it can be fastened correctly.
3.1.4 Ambient temperature
The allowed operation temperature for the pyrometer is 0°C to 70°C. Therefore if pyrometer is to be used
above 70°C upto 200°C water cooling jacket with built in air purge unit is used otherwise it may damage the
pyrometer. The ambient temperature is dependent on the temperature and flow rate of cooling water. Details of air
purge & water cooling jacket is given in point 3.2.
3.1.5 Atmospheric conditions
The pyrometer cannot receive the full infrared energy for the measurement if atmospheric conditions like
smoke, dust or steam are present and hence it result in measuring error. An air purge unit can be helpful to avoid
contamination such as dust and humidity on the lens. The air supplied should be at normal temperature with oil &
moisture free. The air purge generates an air stream shaped like a cone and blows particles from the lens area.
The minimum width of the pouring stream must be 33% of the width of the horizontal measuring width.

"Parameters” and select or type in the desired emissivity
directly in the description field. The emissivity value will be
transferred to pyrometer by hitting the "TAB " button.
(B) Match This parameter is used to match the known target
temperature value to be displayed by the pyrometer. The User
can enter the required temperature in window provided. This
value can be set by clicking on the “Match Temp.” parameter in
the software. The pyrometer automatically adjusts the
emissivity so that the temperature display indicates the same
temperature.
(C) Response time The desired response time can be chosen in
the panel Parameter by clicking the appropriate list box (as per
the values available in the drop box of response time). This
parameter is use to set the analog response time of pyrometer.
(D) Sub Range User can change the sub range of pyrometer in
the panel Parameter. Sub range must be within the basic range
of pyrometer, the minimum span between higher & lower range
is 51. Analog output will be automatically set according to the
sub-range by hitting "TAB" button.
(E) Sensor Type It shows pyrometer sensor type. User can
change sensor type from two color to single color and vice versa
(only applicable with two color pyrometer).
4.2.2 Temperature
It shows the temperature measured by the pyrometer
4.2.3 Parameter Setting
All user selectable device parameters can be set by using the software in the Panel "Parameter"
For communication of multiple pyrometers, select different com port and address.

(E)Switch off level% ( for two color pyrometer) The switch of level is the function that is used to avoid measurement
errors caused by signals, which are too low. Although factory default is set to 15 %, the switch off limit can be
adjusted between 2 and 50%.
(F)Unit User can change the measuring unit of temperature from “Centigrade" to “Fahrenheit" and vice versa.
(G)Peak Picker If the peak picker is switched on, the highest last temperature value will always be displayed and
stored. This feature is particularly useful when object temperature is not uniform across its dimension or the
pyrometer is not constantly viewing an object to be measured.
Peak Picker Functions :
Peak picker can be turn ON & OFF by using the software. When Peak picker is ON, the peak picker menu is enabled for
setting of the parameters like decay rate function, reset below temperature and peak picker delay.
(I)Decay rate The Decay rate range is 0.00 to 166.66°C/sec. or 0.00
to 300°F/sec. depending upon °F/°C unit’s selection. The slowest
Decay rate is 0 degrees per sec. This feature helps to eliminate
erratic measurements and allows the peaked value to decay down
to lower process temperature values as they occur. Decay rate is set
to retain peak measured temperature value and ignore momentary
decreases in measured temperature.
(ll)Delay Time This function set the delay time in sec. before peak
picker function starts. The delay time is selectable in the range 0.02
to 10.00 sec. Zero (0) turns delay time OFF. This function is used to
delay the start of peaking action for upto 10 sec. following the
detection of leading edge of a new target.

(H)Relative energy(for two color pyrometer) The relative energy shows a signal weakening which can be caused by
contaminations of the optics or a viewing window or by dust in the field of view or a too small measuring object.
Relative energy shows the measured intensity compared to the intensity, a black body radiation source would have
at a determined ratio temperature of the pyrometer.
(I)Analog Range User can select the analog range from the option 4-20mA, 0-20 mA & 0-10V.
(J)Comm. Mode User can select the communication mode as per requirement [RS-232 / RS-485].
Note: For connection diagram from RS-232 to RS-485 & RS-485 to RS-232 Refer Page No:-9
To view parameters of multiple devices select the pyrometer name from the drop down list that appears at the top of
