4.1.1 Installation conditions of receiver unit and transmitter unit
4.1.1 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 lengths (diameter)
(12) Vibration
(13) A place with less corrosive gases
(14) A place accessible for maintenance and check
(Refer to "4.2 Mounting dimensions".)
(15) A place with less electrically induced disturbances such as high electric currents or sparks in the sur-
rounding.
(16) Light axis fluctuation: ≤ 0.3°
Notes:
• When there is a possibility of deflecting the laser light axis or reducing the light intensity due to the
large vibration acceleration, contact the manufacturer before installation.
• When "Box Temperature Warning" is occurred under the influence of gas temperature, mount the re-
ducer to keep the receiver box and the transmitter box away from the stack.
• When you measure the high temperature gas of 500°C or more, install a pressure sensor on the purge
line to monitor the purging status. Measuring the high temperature gas without air purge may cause
damage to the analyzer.
• Be sure to keep purging the analyzer once you installed it. Purging is required even you suspend the
operation. Leaving the analyzer without purging causes permanent contamination which may result in
a malfunction or error.

4.1 Requirements

: 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.
: Refer to "1-1 (4) Measurable component and range" in APPENDIX
1. A place where the stack is not distorted or laser light axis is not
deflected by sudden temperature change.
: ±10kPa
: 50vol% or less (no condensation)
: 25m/s or less (However, consultation is necessary for the environ-
ment where dust (1g/Nm
ists.) (Prevention of dust deposition or dew condensation due to in-
crease of air purge flow rate is required)
3
: 15 g/Nm or less (depending on the conditions such as measurable
components, device specification, optical light path, particle diame-
ter, and so on)
: Prepare the flange diameter selected by the 9th digit of the code
symbols. 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. Prepare N
cluding air purge version (4th digit of code symbol is T or V).
: 20L/min or more (depending on measured gas temperature, velocity,
pressure, moisture or dust) (One-side air purge flow rate (L/min) ≥
Gas velocity (m/s) × 10)
: 0.5 to 10 m (0.5 to 5 m for CO+O
: 0.5G or less (0.2G or less for frequency 20 to 40Hz)
