Warnings and Cautions
Please use the thermometer correctly by keeping the following items.
In addition, please read this instruction manual carefully and keep it at the place
where you can access easily.
The mark indicates prohibited operations.
Warning (May cause death or serious injury)
Don’t operate the thermometer in places where combustible or volatile gas is existed.
It is extremely dangerous to use the thermometer in such environment.
When connecting cable connecter, make sure that all mains is turned
off to prevent an
electric shock.
Don’t use the thermometer if it was broken, smoking or nasty smelling.
These may cause fire. For such abnormal c
ondition, turn off the power switch at once
and contact your sales agent of CHINO Corporation.
Using “telescope” (Model: IR-ZYTS), do not see the object exceeding 1500ºC
directly.
Using “Laser pointer” (Model: IR-ZYLZ1) may damage your eyes. Do
n’t stare into a
laser beam. Make sure to target the laser when you want to
decide the center of the
measuring object only and to go off it after the center of the measuring object is
decided.
Never take the thermometer apart or convert it. These may cause trouble and danger.
Caution (May cause injury or physical damage)
Be careful not to give vibration or impact to the thermometer. Install the thermometer
by keeping it as far as possible from an inductive oscillator or electric power line.
Do not use the thermometer in dusty places, noisy places and static electricity places.
Do not wire the connection cable near a noise occurrence resource, relay drive line,
high frequency line and power line.
Do not bundle the connection cable with the line that noise is doubling, and do not
store it into the same duct.

1. Introduction
1.1 General
The IR-SA series is an infrared radiation thermometer.
These thermometers has fixed focusing of long-distance factor, ability of working in 0 to 90ºC ambient
temperature, for free installation.
The radiation energy collected through the objective lens is transmitted to the element is converted into
an electrical signal. The element output is digitally converted and processed through emissivity
compensation, linealizer and modulation. The standardized final output is 4 to 20mA DC. Connected to
“Setting display unit” (Model: IR-GZ), make programming or selection of emissivity, signal modulation
and alarm function easy.
Various options and accessories are prepared for every kind of applications.

4. Installation (refer to [3. Names and functions of component parts].)
4.1 Precautions in Installation
This IR-SA series radiation thermometer is a sensitive instrument.
Install it by referring to the following cautions.
●Vibration and impacts
Vibration or impacts reduces the liability of the thermometer and causes an
unstable measurement by the targeting shake to a measuring surface.
If you install the thermometer in the place where vibration or impacts exist, its
careful periodic inspection is requested.
Caution
●Induction
The thermometer is designed for anti-
induction but install it as far as possible
from an induction heating generator and power line distance factor.
Caution
●Working temperature
The working temperature of the thermometer is 0 to 90ºC. If the ambient
temperature is high, or if the temperature of the thermometer exceeds the
maximum working temperature by reflection from a high temperature
substance, etc., water-cooling of the thermometer is absolutely necessary.
When the temperature of the thermometer
does not exceed but closely reaches to
the maximum working temperature, water-
cooling of the thermometer is
recommended for maintaining of the reliability of the thermometer.
Caution
●Optical path
Select a place for installation of the thermometer, where water-
drops, dust,
smoke, steam, etc. would not enter between the thermometer and a measuring
surface.
If such place cannot be selected and the affection by existence of such substan
ces
cannot be ignored, blowing-out of such substance with air-purge is necessary.
Caution
●Disturbances to make indication of measured value higher
Select a place for installation of the thermometer, where sunlight, light of
incandescent lamp, flame, heat radiat
ion from a high temperature substance,
etc. is not reflected to the measured surface and the cover glass of the
thermometer. When such light is reflected, higher temperature than the exact
one will be indicated. (The affect by such reflection will be great
for the
measurement of low temperature.) If such place cannot be selected, shade the
thermometer or take similar precautionary measures.
Caution

Considering the dislocation of the optical axis, take the measuring area more than 1.5
times the measuring diameter.
At focusing position of object lens, the relation of measuring distance and the measuring diameter are
defined by the distance factor as shown in the following formula.
In case of IR-SA, distance factor and focusing position of object lens are shown in model name, the
number of next beginning of alphabet shows it, and next number shows focusing position of object
lens.
In position that does not focus, the relation of measuring distance and the measuring diameter are
different. In this case, the relation of measuring distance and the measuring diameter are defined as
shown in the following formula, assumed distance of focusing position of object lens from the
thermometer is A, measuring diameter at focusing position is B.
It is an upper figure to have shown these expressions of relation s to the figure. 10 of the whole
expression of relations is an object lens diameter.
Place the thermometer at the measuring distance, confirmed measuring diameter by an upper figure or
formula.
Measuring diameter (mm) = Measuring distance (mm)/distance factor

When measuring distance is nearer than the focusing position of object lens
Measuring diameter = ( B – 10 )×Measuring distance /A+ 10
When measuring distance is longer than the focusing position of object lens
Measuring diameter = (B + 10 ) ×Measuring distance /A – 10 Unit (mm)

The emissivity are values determined by the material of object, profile of its surface, surface roughness,
oxidized or not, measuring temperature, measuring wavelength and other factors.
They are represented by the thermal radiation ratio "" when a black body furnace at the same
temperature is measured in the same wavelength band.
The emissivity "" is generally known by a value at the wavelength of 0.65µm when an optical
pyrometer is used. The emissivity changes according to the above factors even in case of the same
material. Please use the following table as a reference.
