TQ-PSA-type human electrostatic discharge alarm system is designed for the petrochemical industry, a new generation of explosion-proof products. It can intelligently detect whether the human body static voltage is switched on in addition is completed, when the human body static voltage value at risk, audible alarm. It uses a special conductive plastic material, effectively extending the electrostatic discharge time, secure the release of electrostatic energy, electrostatic discharge during the body, to ensure that no sense of shock, no spark, the complete elimination of fire and explosion caused by static electricity hazard. And specially the "Please eliminate the human body static" warning signs, nice shape, for the safe production provided strong support. Without replacement during Features 1. Ultra-low-power design, the normal use the battery; 2 touch sensors, no mechanical moving parts; 3. overall epoxy resin encapsulated, corrosion resistance, waterproof, moisture-proof; 4. proof touch the ball, safety discharge static electricity, human contact does not produce a sense of shock; 5. audible alarm, indicating the state of equipment in real time, easy to use; 6. independent testing ground wire, grounding resistance ≤55Ω, ensure reliable grounding.
