ID-471 Anti-Static Regimes

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 vapours 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. The Model 471A Conduction to Ground Monitor provides a simple to use and robust unit for checking the effective resistance between an operator and ground. The unit can be mounted at the point where personnel enter a hazardous area from a safe area, and may be used to prevent entry of staff with inadequately conductive footwear.

ID-471A Conduction to Ground Monitor

The ID-471A Conduction to Ground Monitor is a control and display unit that is connected by cable to a stainless steel plate on the ground just in front of the wall-mounted unit.

If the resistance is above the values set in the unit (normally set to 108 ohms) the red lamp is illuminated and if the resistance is below the set value then the green lamp is illuminated.

ID-471B Conduction to Ground Monitor

The ID-471B Conduction to Ground Monitor is a control and display unit which is connected by cable to a stainless steel plate on the ground just in front of the wall-mounted unit.

By standing on the metal plate and holding the test handle on the wall unit the monitor circuit is activated and the electrical resistance is measured between the hand and the floor plate. If the resistance falls outside the two set values of 100Mohm and 5Mohm the red indicator is illuminated corresponding to the red portions of the analogue meter display, but if the resistance is between these two values the green indicator is illuminated.

ID-471LC Low-Cost Battery Powered Conductive Footwear Tester

The ID-471LC is a battery-powered Conduction to Ground Monitor which provides a very cost effective, simple and reliable means for screening personnel entering sensitive areas for the effectiveness of their conductive footwear to avoid the build-up of electrostatic charges on the human body.

By standing on the metal plate and depressing the “PUSH TO TEST” button on the wall unit the monitor circuit is activated and the electrical resistance is measured between the hand and the floor plate.

The equipment provides a simple Red/Green indication if the resistance is above or below the pre-set value of 100MΩ. The red lamp is illuminated if the resistance is above the pre- set value and the green lamp is illuminated if the resistance measured is less.

ID-471P Portable Wrist Strap Tester

Based on the proven technology within the ID-471 range of footwear testers, the engineers at IDB Systems have packaged this technology into a small robust case to provide customers with a durable wrist strap tester.

The standard unit is configured in accordance with BS EN 61340-5-1 and will test for over and under resistance parameters.

To maintain conformance with the rest of the ID-471 range of conduction to ground monitors, the ID-471P also has a small self-test switch located on the top of the unit.
