Study For Calibration Equipment Of Smoke Telescope

Smoke Telescope is used to monitor the environmental protection department of degreeof carbon black (concentration) measurement instruments, as part of the environmentalprotection compulsory verification instrument. Along with our country environmentalmonitoring strength enhancement, in each of the environmental monitoring station at thecounty level and above are equipped with many sets of soot telescope. At present there aretwo main types of soot telescope: a visual instrument; Another kind is electronic smoketelescope, using photoelectric diode receiving smoke signals, and then use software tosalinger blackness values. There is no smoke telescope inspection standard device, countriesalso does not have the corresponding verification procedures. The device put into use, enrichthe technical means of detection. Using the theory of the set of device for detecting researchwill be able to make contribution to realize the technology sharing, optimization method; Andalso can produce certain economic benefits.Smoke Telescope prover used stable parallel light source, standard salinger blacknessfigure reticle, accurate emersion the slinger, black grade standard. Using programmablestepper motor controller, stepper motor drives, implements the manually or automatically(programmable) in different salinger, accurate conversion between the level of blackness.Aim the measuring optical path of photoelectric smoke telescope verification device of theoptical system, photoelectric smoke telescope shows value compared with the standard valuesof verification device is given, calculate the error value, solve the problem of the traceabilityof photoelectric smoke telescope. For the metrology department and soot telescopemanufacturers do conformity assessment test, factory inspection and verification work in thefuture when the standard device.The success of this device is developed to fill the gaps in the domestic market. Ensure theSmoke Telescope verification/calibration and type of the implementation of the evaluationwork. Place in hebei province after the success of the metrological verification procedures todeclare, Smoke Telescope verification work will form a complete set of disseminationtraceability system.
