4.1.1 Installation conditions of receiver unit and transmitter unit
Select a location that meets the following conditions.
(1)
Ambient temperature
(2)
Ambient humidity
(3)
Measured gas temperature
(4)
Measured gas pressure
(5)
Measured gas moisture
(6)
Measured gas velocity
(7)
Dust
(8)
Companion flange
(9)
Air purge
(10) Air purge flow rate
(11) Path inner lengths (diameter) : 0.5 to 10m
(12) Vibration
(13) A place with less corrosive gases
(14) A place accessible for maintenance and check
(Refer to "4.2 Mounting dimensions of receiver unit and transmitter unit".)
(15) A place with less electrically induced disturbances such as high electric currents or sparks in the sur-
rounding.
Note) When there is a possibility of deflecting the laser light axis or reducing the light quantity due to the
large vibration acceleration, contact the manufacturer before installation.
Note) When "Box Temperature Warning" is occurred under the influence of gas temperature, mount the
reducer to keep the receiver box and the transmitter box away from the stack.
4.1.2 Installation conditions of control unit
Select a location that meets the following conditions.
(1)
Ambient temperature : –5 to 45°C
(2)
Ambient humidity
(3)
Power supply
(4)
Avoid a place that receives heavy vibration.
(5)
A place which is clean around the analyzer
(6)
A place accessible for maintenance and check
(7)
A place with few electrically induced disturbances such as high electric currents or sparks in the sur-
rounding.

4.1 Installation conditions
: A place where the temperature is within -20 to 55°C and there is no
sudden temperature change.
: A place where the humidity is 90% RH or lower not subjected to
condensation.
: A place where the temperature is 450°C or less, and stack is not dis-
torted or laser light axis is not deflected by sudden temperature
change.
: ±10kPa
: 50vol% or less
: 10m/s or less

: 5 to 10g/Nm
conditions)
: Prepare the flange diameter selected by the ninth digit of the code
symbols. Also, when the purchase specification is provided, prepare
the flange diameter described in the specification.
: Prepare the instrumentation air containing no oil or water. If there is
a possibility of containing oil or water, install an oil filter or a mist
filter. When the instrumentation air cannot be supplied, install a
compressor.
: 20L/min or more (depending on measured gas temperature, velocity,
pressure, moisture or dust)
: 0.5G or less (0.2G or less for frequency 20 to 40Hz)
(When the measured optical path length is 1m)
: 90 % RH or less
: Rated voltage
: 100V to 240V AC
Rated frequency : 50Hz/60Hz
