1.1 Summary
The infrared moisture meter IR-M2 series is designed as a fiber optic moisture meter for
on-line moisture meter utilizing infrared absorption of moisture, and it consists of a detector
unit, a fiber optics,a setting display unit and accessories.
The detector unit is provided with 99 built-in calibration curves to output linear analog
signalsaccording to the moisture.
Since the detector unit provides keys, digital displays and communications function, it can be
used as a single unit or combined with a personal computer.
Two kinds of fiber optics, reflective type and transparent type, are available. The reflective
type fiber optics is for moisture measurement in powder state or in sheet state objects and the
transparent type fiber optics isfor moisture measurement in liquids by combining with a
measuring cell for liquids.
Up to 9 detector unit can be connected with the setting display unit which can set various
parameters of the detector unit and displays the moisture value digitally.
Accessories including cablesand output checker plate are available for various applications.
This manual describes about the detector unit, the fiber optics (reflective type and transparent
type), the measuring cell for liquids and accessories.
For the setting display unit, refer to a separate instructionmanual for it.

3.2 Installation of reflective type fiber optics
There are two types of reflective type fiber optics. One is “Without lens (IR-WCRN)” and
the other is “With lens (IR-WCRE)”.
3.2.1 Installation of tip part
Set an attached holder to the installation place first. Insert the tip of fiber optics into the hole
of the holder and fix it by tightening the tip fixing screw. Two types of holder, horizontal
mounting type and flange type are attached.

3.2.2 Air purge (Only IR-WCRN)
When air purging is required, supply dry air not
containing oil, dust,etc.from apurge air inlet.
Connect a nylon tube of φ6mm in outer diameter and
φ4mm in inner diameter to the purge air inlet.
(When the reflection type fiber optics is used in
ambient temperature more than 60°C, remove the
purge air inlet and pipeto the screw hole of RC1/8

3.2.3 Connectionswith detector unit
Connect the side being separated into two parts of light projecting side and light receiving
side with the fiber optics connectorsof the detector unit.
The fiber optics has “Light projecting
side (D)”and “Light receiving side
(E)”and each one has a carved mark. Connect the fiber optics through the
rubber bush as shown in the following figure.

3.2.4 Optical path
Select a place where water drops, dust particles, smoke, water steam,etc. will not enter
between the tip of fiber optics and an object. If these substances cannot be prevented and
their influences are negligible, purgethem with air, or other remedial measure is necessary.
If direct current (DC) light like the natural light, which does not change its intensity
momentarily, comes to an object, it does not cause any disturbance in measurement, but
alternate current (AC) light like as electric bulb, flame,etc., causes disturbance. Further,
strong light such as direct sunlight also causes disturbance. In such cases, it is necessary to
shade the disturbing light to prevent it from direct shining on an object.
3.2.5 Measuring place (for objects of pulverizedor granular substance)
For installation of the tip of fiber optics on on-line, select a place where the moisture
difference is small between the surface and the inside of an object, like as at a hopper outlet
or just behind the conveyor belt transfer place. If such a place cannot be selected, face the
inside to the surface by using a baffle plate during measurement as shown in the figure.
3.2.6 For the objects in sheet state such as paper,etc.
Tilt the tip of fiber optics by 15°from the vertical face as shown in the figure.

between the detector unit and the measuring cell. Make sure to connect the light projecting side
and the light receiving side of the fiber optics to the correct sides of the detector unit and the
measuring cell.
Fix the fiber optics with appropriate metal toolsat several places for
avoiding affect with vibrations, etc.
Make sure not to bend the fiber optics below its minimum bending

3.3.3 Disassemble cleaning
For accurate measurements, recommend periodical cleaning of the cover glass in a liquid
contacting part of the measuring cell.
1)Remove the fiber optics (both of light
projecting side and light receiving side),
from the measuring cell.
2)Next, remove 4 screws fixing aconnecting
part and remove the connecting part from
the liquid-contacting part.
3)Remove a fitting ring by using the tool A.
Then after screwing the tool B into the
cover glass, pull out the cover glass from
the liquid-contacting part.
4)Wipe off dirt on the glass surface with a
gauze,etc.
5)Confirm that an Oring is inserted in
liquid-contacting part and push in the
cover glass to the liquid-contacting part.
6)Match the positionsof E and D characters
of the connecting part and the liquid
contacting part,and fix the connecting
part.
7)After the cleaning of the cover glass, make
sure to re-calibrate your moisture meter.

Warning
Induction
The detector unit is designed for anti-induction. However separate
the
detector unit from induction heating oscillatorsor power
lines as far as
possible.
Warning
Ambient temperature and humidity
The ideal ambient temperature of the detector unit is 10 to 30°C
and the
ambient humidity as low as possible is recommended. In high
humidity
environment,
you may have error in measurement due to condensation of
steam bychange in temperature.

4.1 Connections
The terminal board is accessible by opening the door of the detector unit. Lead in cables
through a small sized cable inlet at the lower part and connect them to terminals. Lead in the
exclusive cable IR-WERT through the large cable inlet.
4.2 Layout of connection cable
For connection of cables, be careful of the following points.
4. Connections
For preventing electric shock,
make sure to turn the power supply off
before wiring.
Warning
Caution
Use a cable conforming to the applicable outer diameter (
φ
4.5 to 6.5
mm)
of the small cable inlet; otherwise waterproofing of the
detector unit may
deteriorate. Tighten the nut at the cable inlet securely after connections.
・Separate the cables from induction heating oscillator and power lines.
・Keep the cables free of deposit of water, oil, etc.
・Don’tbend the cablesextremely or apply any excessive force to them.
・
For permanent layout, protect the cables with conduits, etc.

4.3 Multi-detector connections
By using the setting display unit, you can connect the detector unit up to 9 sets.
Two wiring methods are available. One is wiring through a relay box (IR-WEE) and the other
is without the relaybox (IR-WEE).
4.3.1 Connections through relay box
4. Connection
Caution
For
both wiring methods, before connecting with the setting display unit or
before turning on the power supply of the setting display unit,
number
setting to the detector units is required. For the number setting, be careful
not to overlap any detector unit number of each detector unit.
Refer to [6.2 Setting of detector unit number] for the details.
Caution
1. Shorten the length of exclusive cable (IR-WERT * mark) as much as
possible.
2. For wiring to the relaybox, refer to “Instruction manual of relaybox”.
