1. Introduction
1.1 General
The IR-E series scanning radiation thermometer, having a rotary mirror built in the detector
unit, is designed to measure unidirectional temperature patterns of an object without contact
and performs the temperature measurement of 50°C to 1200°C.
The IR-E series consists of the detector unit (Model IR-E) and the high-speed
display/processing unit (Model IR-EPG), and exclusive accessories of the protective case and
the air-purge hood for the detector unit are added as needed.
The detector unit measures the thermal radiation energy from a measuring area by scanning
measuring positions optically by the rotary mirror, and converts the measured temperature into
an electric signal that is transmitted to the high-speed display/processing unit with an
exclusive connecting cable.
The connecting cable is shipped with the length specified, but the cable length can be changed
within 200m without any effect to functions.
The high-speed display/processing unit performs indication/recording and analog output of the
measured temperature after arithmetic processing such as emissivity compensation,
linearization, signal modulation, etc. on the temperature pattern signal transmitted from the
detector unit.
2 kinds of connection types of a connector connection and a terminal connection are available
on the detector unit. The connection type of your detector unit has been selected by your
ordering specification.
This manual describes operations and configurations of the detector unit, the protective case
(Model IR-ZEPW), and the air-purge hood (Model IR-ZEAH). Confirm the name and model of
the instrument you purchased and read corresponding paragraphs in this manual.
A separate manual is prepared for handling/operation of the high-speed display/processing unit,
read it along with this manual.

2. Configuration
The IR-E series scanning radiation thermometer consists basically of the detector unit, the
relay box and the high-speed display/processing unit. Unidirectional temperature patterns,
trend graphs and thermal images are displayed on the high-speed display/processing unit.
The scanning radiation thermometer detector unit (Model IR-E) and the relay box (Model
IR-ZEB) are connected with the exclusive connecting cable (Model IR-ZEST or IR-ZESC).
The connecting cable has been shipped with the length specified, but the cable length can be
changed within 200m without any effect to functions.
For the scanning radiation thermometer detector unit, in addition to the detector unit, the
protective case (Model IR-ZEPW) for housing the detector unit in the temperature
measurement at a site under such hostile environment as high temperature, high humidity,
smoke, dust, oily smoke, etc. and the air-purge hood (Model: IR-ZEAH) for clearing the
optical path are prepared as accessories.

3. Detector unit
The detector unit is a single-color narrow-band radiation thermometer using the detecting element
of PbSe (4.0μm measuring wavelength). Its drive power is supplied from the relay box. By
scanning the measuring area optically by the hexahedron rotary mirror, it measures
unidirectional temperature patterns of an object and transmits the measured temperature as the
electric signal of 0 to 1mADC to the relay box.
In the relay box, the electric signal of 0 to 1mADC is converted to 0 to 5VDC that is transmitted
to the high-speed display/processing unit.
It measures temperature with the wide scanning angle of 50° and the high scanning speed is as
fast as 50 times/second.
2 kinds of connection types of the connector connection and the terminal connection are
available. The connection type of your detector unit has been selected by your ordering
specification.

3.3 Precautions for installation
(1) Vibration and impacts
The detector unit is designed to withstand the vibration of 29.4m/s2 (3G), but vibration or
impacts reduce the liability of the detector unit in the long term and cause an unstable
measurement by the position movement of a measuring area.
When vibration is intense especially, it is effective to insert cushion materials like a rubber
board between the detector unit and a fixing stand.
(2) Induction
The detector unit is designed for anti-induction but install it as far as possible from
induction heating equipment or power lines.
(3) Working temperature and humidity
The working temperature of the detector unit is 0 to 50°C. When the ambient temperature
is higher than 50°C or reflection from a measuring area or hot air is strong, use the
protective case for cooling the detector unit by water.
When the ambient temperature does not exceed but closely reaches to 50°C, it is recommended
to cool the detector unit by water for maintaining of its reliability.
In addition, control humidity in environment as low as possible. High humidity absorbs and
scatters thermal radiation in the optical path.
(4) Optical path
Select a place where water-drops, dust, smoke, steam, etc. do not enter between the detector
unit and a measuring area.
If such place cannot be selected and the affection by existence of such substances cannot be
ignored, purge such substance with air or other arrangements are necessary.
(5) Measurement distance
The measurement distance of the detector unit can be arbitrarily changed in 0.5 to 10m but,
since the scanning angle is constant, the scanning width of a measuring area becomes large
as the measurement distance becomes large.
Allow for a margin of the scanning width in consideration of fluctuation of a measuring
area, displacement of the optical path, etc.
Scanning width = 2 X (Measurement distance + 47) x tan25°

3.4 Layout of connecting cables
For connecting the connecting cables, be careful of the following points.
Caution
3.5 Connections
(1) Connections of terminal connection type
By removing the terminal board cover on the
upper side of the detector unit, 5 pieces of
terminals are arranged as shown in the right
figure.
Connect wires of the connecting cable to each
terminal.
Since the wires of the connecting cable are
identified by colors, connect them as shown in
the right figure.
Caution
Remarks
(2) Connection of connector connection type
The connection is completed by coupling the connector of the connecting cable to the
connector on the upper side of the detector unit.
x For the coupling, position key slits of both connectors and push the cable connector,
and turn the detachable ring clockwise until it is locked.
x For decoupling, turn the detachable ring counterclockwise for unlocking and pull the
cable connector.
(1) Separate the cables from induction heating equipment and power lines.
(2) Keep the cables free of deposit of water, oil, etc.
(3) Don’t bend the cables extremely or apply any excessive force to them.
(4) Avoid laying the cables at a place in high temperature more than 70°C.
(5) For laying the cable permanently, protect them with conduits, etc.
The outside diameter of the connector attached to the cables is about
ø23mm.

OUTPUT POWER EARTH
The power for the detector unit
is supplied from the relay box
through the connecting cable.
3.6 Operation
Since the drive power is supplied to the detector unit from the relay box, when the relay box is
turned on, the detector unit automatically becomes ready to measure.
However, when the protective case and/or the air-purge hood are used, confirm that cooling
water and/or purge air are supplied in advance.
By starting up the software of the high-speed display/processing unit and then clicking the
measurement start button, the detector unit is put into operation.

3. Fluctuated indication
(1) Is the detector unit fixed firmly and not vibrated?
(2) Are the connectors of the connecting cables connected firmly? Check if there is partial
disconnection in the connector.
(3) Are the terminal screws on the terminal board tightened firmly?
(4) Check if there is partial disconnection in the connecting cable.
(5) Is the power voltage in the allowable range?
(6) Check if there is such disturbance as fume, etc. in the optical path.
(7) Check if the temperature of a measuring area fluctuates.
(8) Check if the emissivity of a measuring area fluctuates. (In case of moving objects especially)
Despite the above inspections, when a cause does not become clear, inform your nearest CHINO’s
agent/distributor of the state and phenomena of equipment. At this time, do not touch internal
mechanisms/circuits by hands.
