Outside line sensor receives, and then trigger signal is externally sent out by control module and is counted etc..
But current spark detector is the problem is that can only be counted and detected to the spark in pipeline, due to only
It is detected by the light of spark, so the sensitivity requirement for infrared sensor is higher, the spirit of infrared sensor
Sensitivity more high detection effect is better, but the sensitivity of infrared sensor can not possibly reach perfect and better infrared ray and pass
Its Costco Wholesale of sensor is also more expensive, so in conjunction with the market demand and price request, the spark detector produced at present still can be right
There are error, wrong reports for the detection of spark, and error rate and rate of false alarm are still higher.
