Introduction
About CALsys 37BB
The ‘CALsys 37BB’ has been designed to provide stable and accurate temperature source for on-site
and laboratory calibration of radiation thermometers by comparison method up to a temperature
range 50°C.
The ‘CALsys 37BB’ model has been designed in single part. This model provides an isothermal
enclosure in which the non contact pyrometers can be checked against the temperature of the
calibration black body. For traceable calibration a master pyrometer should be used. The unit's
features emissivity of 0.98 thus offering the closest approximation of a target surface that is a perfect
emitter of infrared energy. This model is suitable for onsite and the laboratory use for stable
temperature readings.
The ‘CALsys’ models are part of wide range of portable calibrators designed and made by us. Please
contact us in case you required more information about our other products.

Basic Working Model of CALsys 37BB
‘CALsys 37BB is a transportable, self contained unit designed for use on any reasonable flat surface.
The target is a ridged aluminum plate which is painted by a high emissive paint .The target is heated
by Si Rubber heater which allows the source to heat up to 50°C in about 15 minutes and holds it
stable at temperature within ±0.04°C. The heater blockhouses consists a heater & the controller
sensor. The temperature controller to sense the block temperature uses this sensor. To obtain the
maintain a required temperature the controller varies the power to the heaters via a solid-state relay.

Optics
The pyrometer measures the temperature by receiving heat radiation from the object whose
temperature has to be measured. This heat radiation is passed through the lens sensor and 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.

Manufactured working distance is mention on pyrometer.
If the pyrometer is not installed at manufactured working distance (WD) then spot size at actual
installed distance should be calculated. For example, if factory made working distance is 500 mm &
pyrometer is AST A250 (250 - 1800°C) then spot size is 5mm (as given in table). If user installed this
pyrometer at 1000mm then spot size is not 10mm (as given in table), user should have to calculate as
given below method.

Case-I: If installed working distance is greater than manufactured working distance
Case-II: If installed working distance is smaller than manufactured working distance
Where, S = manufactured spot size of pyrometer(mm), A = It shows the value of lens opening
(aperture in mm)
Distance of pyrometer from object
The desired spot size on the target will determine the maximum measurement distance and the focal
length of the optical module. To avoid wrong readings the spot size of target must contain entire field
view of the pyrometer. The pyrometer must be mounted so the entire field of view is the same or
smaller than the desired target size. This is indicated in the below diagram.

CALsys 37BB

Viewing Angles
The pyrometer can be placed at any angle from the target object up to 30°. Indicated in the below
diagram.
