PERSONAL ELECTROSTATIC ELIMINATOR DEVICE
PERSONAL ELECTROSTATIC ELIMINATOR DEVICE-also known as a static discharge device-is a product designed to safely dissipate static electricity accumulated on the human body in environments that are flammable, explosive, or require anti-static precautions. Its use helps prevent fires, explosions, and electric shocks caused by human-generated static electricity, while also reducing electrostatic damage to electronic components.
1.Data Sheet
The electrostatic discharge (ESD) ball features an assembly comprising a stainless steel post and a touch sphere made of either stainless steel or anti-static plastic:
1. Electrical and Performance Parameters:
Surface resistivity: 1.0 × 10⁶ Ω ~ 1.0 × 10⁹ Ω (utilizes semi-conductive material to allow for the slow release of static electricity, preventing sparks).
Charge transfer: <0.1 μC.
Static discharge time: ≤ 100 ms (instantly dissipates accumulated static charge from the human body).
Grounding resistance: <55 Ω (some high-standard facilities require <10 Ω or <60 Ω).
Withstand voltage: ± 15 kV ~ ± 20 kV.
Alarm function (for electronic alarm models): Operating voltage 3.6V/5V; operating current <10 mA; features audible and visual alarms.
2. Mechanical Structure Parameters:
Touch sphere diameter: Typically Φ 90 mm.
Sphere/Body material: The touch sphere typically uses conductive semi-conductive material (such as specific PE or special nylon), while the post and main body are made of 304 stainless steel.
Post dimensions: Steel tube diameter Φ 38 mm or Φ 51 mm; wall thickness 1.0 ~ 1.2 mm.
Total product height: 1000 mm.
Grounding wire length: Standard 3-meter straight or coiled cable.
2.Installation and Use
The human body electrostatic discharge ball should be installed directly at personnel entry/exit points outside the electrostatic protection zone-such as at the entrance to a storage tank stairway or outside a pump room-using either a pole-mounted or wall-mounted configuration; a standard flange (e.g., Φ150mm) is typically used to secure the base firmly.
The unit is equipped with a grounding wire that can be pulled out from beneath the base and connected to a grounding system; the grounding resistance must be less than 10Ω (or 55Ω, depending on the specific product) to ensure reliable grounding. To operate, simply touch the metal ball for 2–5 seconds-or for 10–15 seconds, if required by specific regulations-to fully dissipate static electricity.
It is recommended to periodically inspect the grounding wire and connection points to ensure good electrical conductivity.

4.Applications of PERSONAL ELECTROSTATIC ELIMINATOR DEVICE
- Industrial and Hazardous Material Safety (Static Discharge Spheres): In flammable or explosive environments, static electricity carried by the human body can ignite gases or dust; static discharge spheres allow for the safe dissipation of this static charge.
- Chemical Plants and Gas Stations: Installed at oil depots, beside fuel dispensers, or at facility entrances for personnel to touch upon entry or exit, preventing fires caused by static electricity. Distilleries and Gas Facilities: Used to eliminate static electricity from personnel in high-risk areas involving alcohol vapors or gas transmission. Coal Mines and Explosives Warehouses: Prevents static sparks from igniting mine gas or explosives.
- Electronics Manufacturing and Precision Electronics Laboratories: Used to neutralize static electricity around production lines or workstations, preventing electrostatic discharge (ESD) from damaging sensitive electronic components. Laboratory Materials Testing: Used to evaluate the dielectric strength of insulating materials or to conduct static electricity simulation experiments.
