product description
The ZD-PSA human body electrostatic discharge alarm is a new generation of explosion-proof product designed for the petrochemical industry. It can intelligently detect whether the static voltage of the human body has been removed. When the static voltage of the human body is at a dangerous value, it will give an audible and visual alarm. It is made of special conductive plastic material, which effectively prolongs the static discharge time and safely discharges static energy. During the static discharge of the human body, it ensures no sense of electric shock and no sparks, eliminating the hidden danger of fire and explosion accidents caused by static electricity.
At present, some flammable and explosive dangerous places still use metal conductors to directly ground and discharge to eliminate human body static electricity. Although this method can eliminate the static electricity of the human body, this method uses the form of discharge between conductors to release the electrostatic charge, the release resistance is small, the static release time is short, and the instantaneous release of energy is large, which may cause electric shock to the human body or cause the possibility and inevitability of fire and explosion accidents. .
The ZD-PSA human body electrostatic discharge alarm makes up for the shortcomings of the current human body static electricity removal method, reasonably releases the human body electrostatic resistance, prolongs the human body static electricity release time, reduces the human body’s instantaneous release of static electricity, and effectively avoids the occurrence of fire and explosion accidents and the human body The phenomenon of electric shock. At the same time, the ZD-PSA human body electrostatic discharge alarm touch-sensitive human body is in reliable contact with the touch ball, there are no moving mechanical parts, and the sound and light alarm prompts whether the electrostatic discharge is complete.
