Application characteristics of spark detectors in the metal polishing industry: 1. Suitable for pipeline process temperatures below 100 degrees Celsius, with high-speed movement of polishing metal dust; 2. The detection medium includes organic dust, inorganic dust, and metal polishing dust; 3. Quickly respond and cooperate with the pipeline backend fire extinguishing system; 4. Equipped with a pressurized water control system, variable frequency pressure regulation of 6-10 kilograms; 5. Alarm and stop the power equipment to prevent hot particles from entering the dust removal system, causing risks to the pipeline or dust removal system.
