Pneumatic conveyer pipe way spark probe

The utility model relates to a pneumatic conveyer pipe way spark probe, including detecting head, shell and acquisition circuit, the shell sets up outside the detecting head, the detecting head includes infrared sensor and infra -red filter, but infra -red filter filtering 400nm~800nm's visible infrared light is greater than 800nm's infrared light permeable, the infra -red filter cover is established on infrared sensor's the response side. The utility model discloses a pneumatic conveyer pipe way spark probe has add infra -red filter on the detecting head, utilize infrared wave length and the long different characteristics of the infrared wave in the spark in the natural light, filters the infrared light in the inside natural light of imbibition pipelines such as pipeline seam crossing and observation window position, and consequently the final received of response side by infrared sensor has only the infrared light in the spark to the problem of spark probe emergence wrong report has been solved. 本实用新型涉及种气力输
