不透光煙度計使用不透光度記錄柴油機煙度排放，其工作原理如圖2所示。不透光煙度計測量室的光學通道長度是430mm，通過溫控的採樣管路將測量室內部的排氣穩定保持在100°C左右。柴油機排氣通過採樣管路（焊接的採樣探頭）及溫控的採樣軟管，由膜片泵採樣，保持採樣氣體的流量恆定。採樣氣體通過回流管被送回到排氣管中，可以保證壓力變化的情況下的採樣流量恆定。

結果 (英文) 1:

Opacimeter recorded using smoke opacity diesel exhaust, its working principle shown in Figure 2. Opacimeter measurement chamber of optical path length is 430mm, the sampling line temperature control by the exhaust gas inside the measuring chamber is stably maintained at around 100 ° C. Diesel exhaust through the sampling line (sampling probe welding) and temperature control of the sampling tube, the sampling by the diaphragm pump, to maintain a constant flow rate of the sample gas. Sample gas returned to the exhaust pipe through the return conduit, the sample flow can be guaranteed in the case of constant pressure changes.

結果 (英文) 2:

The impermeable smoke meter uses impermeable brightness to record diesel smoke emissions, and its working principle is shown in Figure 2. The optical channel length of the impermeable smoke meter measuring chamber is 430mm, and the exhaust gas inside the measuring chamber is stable lying at about 100 degrees C through the temperature-controlled sampling line. Diesel exhaust is sampled by diaphragm pump through sampling lines (welded sampling probes) and temperature-controlled sampling hoses, which keep the flow of the sampled gas constant. The sampled gas is returned to the exhaust pipe through the return pipe, ensuring a constant sampling flow in the event of a change in pressure.

結果 (英文) 3:

Opacity Opacimeter uses opacity to record smoke emission of diesel engine, and its working principle is shown in Figure 2. The length of the optical channel in the measuring chamber of the Opacimeter is 430 mm, and the exhaust gas in the measuring chamber is kept stable at about 100 ° C through the temperature controlled sampling pipeline. The exhaust gas of diesel engine is sampled by diaphragm pump through sampling pipeline (welding sampling probe) and temperature control sampling hose to keep the flow of sampling gas constant. The sampling gas is sent back to the exhaust pipe through the return pipe, which can ensure the constant sampling flow under the condition of pressure change.
