The equipment can monitor the smoke and dust, through the Ringelmann flue gas concentration daily measurement method, through the high-quality prism telescope, long-distance measurement of the blackness of soot, because it has the advantages of small size, large field of view, long range, fast speed, high precision, easy to carry, etc., so the Ringelmann blackness meter is deeply loved by the majority of users.
How does the Ringelmann Blackmeter work?
The Ringelmann blackness meter uses a binocular prism telescope system, and the telescope reticle is made with grayscale staircase blocks of Ringelmann blackness diagram grades 1-5, and the observer can determine the standard grade of flue gas blackness by comparing the soot target with the grayscale staircase block through the left eyepiece.
What are the parameters of the Ringelmann blackness meter?
Because different products have different parameters, here we take the LY-HD Ringmann blackness meter as an example.
1. The magnification of the telescope's viewing angle is 15 times.
2. Telescope observation distance 10 1000 meters.
3. The clear aperture of the objective lens is 80 mm.
4. Ringelmann blackness level 0 5Level 0.
5. The observation error is not greater than 0Level 5.
6. The camera magnification of the reticle is 2 times.
7. Instrument size: 70*700mm
8. Wear a triangular bracket.
9. It is equipped with a digital camera universal interface bracket, which can be connected to ordinary digital cameras and digital SLR cameras.
How to use the Ringelmann blackmeter
Remove the device from the cassette and remove the degassed eyepiece cap and objective cap.
Aim the device at the place to be monitored (chimney mouth, etc.), adjust the telescope, and when the black smoke to be monitored is clear, the black smoke level can be determined according to the blackness map.
There are a few things to keep in mind when using a Ringelmann blackness timer:
When observing the concentration of smoke gas, the illumination light should be side light (direct sunlight from the sun or other sky light), and should be approximately at right angles to the line of sight, avoiding frontal light and backlight.
When the weather is bad (cloudy, hazy, etc.), the sky background is relatively dark, so when reading the value, you should remember a slightly lower level.
Do not have dark-colored obstacles such as mountains, trees, and buildings in the background of the monitored chimney mouth.
When monitoring the blackness of flue gas, the boiler to be monitored is required to be in normal operation, the boiler is kept at 80% or more of the quota load, and during the monitoring process, no water shall be added to the coal, and no excessive blast dilution shall be allowed.
Shall not be subject to a monitoring result, need to monitor multiple times in a row, each monitoring interval between 10-60 seconds, and record the instantaneous blackness of observation in turn, assuming that the blackness of the flue gas is between the second level, can be estimated to 1 2 levels of blackness value, take the average value of all monitoring data, is the blackness of the monitored flue gas.
Daily maintenance method of Ringelmann blackness meter
The equipment should be kept in a dry and ventilated place, and should be kept away from volatile or corrosive chemicals such as acids and alkalis.
In the process of using the equipment, anti-collision measures should be taken to avoid the equipment being damaged or damaged during use.
Because the whole equipment has been inspected and sealed, it should not be disassembled at will in daily use.
During daily use, the mirror will inevitably have dust and dirt, and it is necessary to wipe it off with a lens brush or lens paper.
After each use, close the eyepiece cap and objective cover, clean the surface of the device, and then put it back in the box.
That's all there is to it: What is the principle of the Ringelmann blackness meter? I hope it helps.
