Performance characteristics of human body electrostatic discharge meter
The human body electrostatic discharge meter is a human body electrostatic discharge product suitable for use in flammable, explosive and antistatic places. It is mainly used in flammable, explosive hazardous areas and anti-static places. The use of this product can safely discharge the static electric charge accumulated by the human body, avoiding the occurrence of fire and explosion accidents caused by human body static electricity and human body electric shock.
The human body electrostatic discharge device is a stainless steel human body electrostatic discharge device, which has a built-in passive circuit system. When the human body touches the steel ball, the static electricity carried by the human body can be controlled by the device, uniformly pressurized, and uniformly discharged to the earth. Avoid electrostatic discharge and cause fire hazards. It has the characteristics of simple installation, stable operation and fast elimination of static electricity. Working principle: The human body is very prone to generate static electricity during the production process, forming a higher voltage than the surrounding environment, and electrostatic discharge occurs when contacting the corresponding object. If the discharge process produces a slight spark and is in a flammable or explosive situation, it will cause serious safety accidents. Therefore, in high-risk situations, it is necessary to strictly control the static electricity of the human body, and timely discharge the static electricity of the human body to the ground. The human body electrostatic discharge meter can adjust and control the relevant parameters of the electrostatic discharge through an intelligent passive circuit to ensure no safety hazards and no sensory discharge of the human body.
Human body electrostatic discharge meter performance characteristics:
1. A special grounding wire is connected to the grounding pile to ensure reliable connection;
2, using stainless steel material, the resistance value is between 106 ~ 109, the release current is small, the discharge time is long, to ensure that no spark is triggered;
3, with a lithium battery inside, no external power supply, easy to install.
4. When the green light is on, the static voltage of the human body is less than 150V, and the static energy of the human body is less than 0.002mJ, which is far less than the minimum ignition limit of 0.018mJ of the petroleum vapor mixture. The static voltage is basically guided out to ensure the safety of the human body;
