SDM is fitted mainly in Boiler exhaust trunking and can be fitted other exhaust pipings as per the company policies. Save the post before we begin :)
Below we have summed it : lets start
The environment 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
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 obscure the light beam and cause 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 semi permanent 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 are light-weight and anti-corrosion Aluminum so it is easy for users to replace spares and maintenance.
There are two Relays for high and high high on Main Panel.
Accordingly, the efficiency of compatibility with other instruments is improved.
Operator can see the status of Smoke by observation of the value on the monitor. Thatβs how system is easily operated by beginner.
