Introduction

This outline is applied to the evaluation of the transmissive type smokemeter, it gives the evaluation of the transmission-type smoke meter Basic test conditions and test methods can meet the standard requirements. This outline is based on JJF 1015-2014 "measuring equipment type and universal norms" and JJF 1016-2014 "count Evaluation of the amount of equipment type outline guidelines for the preparation "Writing. Technical content of this outline the main reference JJG976-2010 "Transmission-type smoke meter", part reference ISO 11614.1999 (E) "reciprocating compression ignition engine measuring flue gas emissions Opacity and a light absorption coefficient of the instrument. " The outline for the first time to develop. Transmissive type smoke meter evaluation outline

1 Scope

This type of evaluation outline applies classification codes to 46,481,000 of Split ① transmissive smokemeter ② (hereinafter referred to as Smoke meter) of pattern evaluation. ① take style known as Split. There are corresponding full-flow opacimeter. ② also known as opacity meter, impervious photometer, opacimeter, light type smoke meter and so on. ③ also known as opacity. 2.

JJG976-2010 and ISO 11614 in some of the terminology and symbols apply to this outline. 3.1 transmittance τ transmittanceτ From the passage of light through dark light emitted smoke-filled, the transmission ratio of the luminous flux and the incident flux τ = Φ0 × 100% (1) Where. Φ --- dark passage full of luminous flux received on flue gas emissions time receivers, lm; Φ0 --- dark passage full of luminous flux received on time and clean air receivers, lm. 3.2 absorption ratio N absorptanceN③ The light emitted from the light source than the flux of the incident light flux absorbed by the dark smoke-filled channels. N = Φ0-Φ Φ0 × 100% = 1-τ (2) 3.3 effective optical path length L effectiveopticalpathlengthL From the light reaches the light receiver instrument light emitted by the dark smoke-filled channel length in m. press ......
