B-I INDUSTRIAL CO., LTD.
SMOKE DENSITY INDICATOR

1-2 INTRODUCTION

The environments is high on the political agenda at the moment and Pollution is still very
much a live issue. Accordingly, we have developed this system to meet requirements for the
Air Pollution Control Act, etc enable to measure and acknowledge the quantity of gas emitted
in order for the prompt response against the status of smoke.
The regulations relevant Air Pollution from ships are as follows;
Canada Shipping Act : Air Pollution Regulations – CRC, Vol. XV, c.1404
SIP – ALASKA – 18AAC 50.700
ETC.
The main purpose of our smoke density indicator is to prevent Air Pollution by installation on
smoke stack on vessels and Chimney on industries.

1-3 GENERAL INFORMATION

Our System consists of Control Panel, Light Beam Projector, Photocell Receiver, Stack
Adaptor and Intermediate Adaptor.
When Smoke is present in the Flue or Chimney, it will obsure the light beam and casue a
change in the electrical signal on the receiver cell.
This change is recognized by the control which displays the information on the panel meter
and the control panel digitalize the electric signal and display the value of 0~100 on the
monitor.
Project is used with High-Brightness LED. The life time of this LED is semipermanent and
light intensity is maintained regularly.
Receiver is equipped with CDS Cell which has characteristics of long life time and liner to
detect light in comparison with other sensors.
The materials of Projector and Receiver is light-weight and anti-corrosion Aluminum so it is
easy for users to replace spares and maintenace.
There are two Relays for high and high high on Main Panel. Accordingly, the efficency of
compatibility with othe instruments is improved.
Operator can see the status of Smoke by observation of the value on the monitor. Our system
is easily operated by beginner.
