As we finish up 2013 and head into the winter season in the Northern hemisphere, static problems begin to become more prevalent again due to the general lower humidity present in most manufacturing areas.
Some of the resulting symptoms of the static condition are: discharges to personnel, jamming, tearing, discharges to machines and sensors. Finally, discharges within a charged material can also cause blemishes to materials that must have absolute clarity within them. We’ve all been the victim of a nasty static discharge at some point or another. You can have the right tool in using an active static eliminator. But how do you know if you have your static eliminator located in the right position for maximum effectiveness?
That is where the EXAIR Static Meter model 7905 comes into play. This easy to use meter will indicate where the static field(s) are located in their process, how large they are in terms of kV / 1 inch distance from the charged target, and their polarity (+ or -). The meter can make direct readings up to +/- 20 kV at 1 inch distance.
The above pieces of information are handy for knowing where to place static eliminators for any given process. Static cannot be seen directly, and so your best bet for implementing an effective strategy is to utilize the Static Meter so that you can maximize static field reduction and minimize the effects of static re-generation by locating your equipment at the best possible points in the process.
