Flameproof Human Body Static Discharge Device – Lamp Unit

Safety device for screening personnel entering areas where electrostatic discharges must be avoided Conduction to Ground Monitor is a control and display unit which is usually mounted on a wall at about shoulder height. This unit is mounted on stainless plate having two handles one is “test handle” to test the resistance and another is “Reference ground handle” having connected to the dedicated earth point where human body is to be discharges .By holding test handle and reference handle on unit the monitoring circuit is activated and the electrical resistance is measured between the test handle and the Reference handle. In a number of industrial operations it is essential for personnel to be effectively bonded to ground at all times to prevent electrostatic spark discharges damaging sensitive electronic components or circuits, or causing ignition of flammable vapors or materials. Bonding to earth may be conveniently achieved via conductive footwear, but it is necessary to know if this bonding remains effective in practice. HBSD-Lamp Unit model provides a simple Red/Green lamp indication if the resistance is above or below the preset value set in the unit . “Red Lamp” is illuminated if the resistance is above the pre- set value and the “Green Lamp” is illuminated if the human conduction value measured is less than pre- set value
