NEOS 30 OEM-DM-Iss.2
1. BACKGROUND
NEOS
The standard NEOS Bars have become accepted as the most effective static eliminators in their respective classes:
from
NEOS 12, which is the most effective short range Bar available
to
NEOS 30, which is the most powerful long range Bar available
Please refer to the comparison between the Simco ThunderION 2.0 and the NEOS 30 which was sent to you in February 2019. It
shows that the NEOS 30 is comprehensively better than the market leader at all distances.
Frequency and Long Range Static Neutralisation
It is useful to repeat these notes, as they are essential for understanding the benefits of the NEOS 30 OEM and where it fits into the
NEOS range.
The method for neutralising at long distance without air assistance is to reduce the frequency of the ion emission so that it
produces bigger fields of ions which propel each other outwards. This is the basic operation for all pulsed DC static neutralisation.
Generally:
- short distances are neutralised with higher frequency – for example, 50 Hz on the 3014 and 3024F
- longer distances are neutralised with slower frequency – for example, 5 Hz on the 3024L
When NEOS Bars are used in intelligent operating modes (AN or AL) they respond to the polarity of the electric field from the
object and change the wave pattern to output more ions of the opposite polarity. This effect also compensates to a large degree
for changes in distance within the sensing range. The unipolar fields in AN and AL modes can be larger and so act like slower
frequency fields.
In AL mode the NEOS 30 can sense a strong electric field at distances up to about 750 mm. In this range there will effectively be
automatic compensation for distance.
If the electric field is too weak, usually because the target is too far away, a Manual setting may produce better neutralisation. For
example, the NEOS 30 in setting M1 (0.5 Hz) neutralises at distances over 750 mm more efficiently than in AL mode.
What if the object to be neutralised moves from a short distance to a distance over 750 mm?
For example, from 200 mm to over 1m?
The NEOS 30 OEM has been developed to deal with this problem.
