Low level indicator
A Series 2300 applicator equipped with a Low Level Indicator will
display a warning whenever the level of adhesive in the tank falls to the
point that the unit should be refilled. The low-level light (see Figure 2.4)
will come on and stay on until the tank is refilled.
Figure 10.3 - Basic Low-Level Indicator
Components (mercury switch and lamp
not shown):
1 Counterweight
2 Pivot Point
3 Lever Rod
4 Float
5 Adhesive Level
The Low Level Indicator consists of a float, a counterweight, a lever
rod, a mercury switch, and a light (see Figure 10.3 for basic
components). The float is balanced by the counterweight such that it
rides half in the adhesive, half out. As the adhesive level drops, the
lever rod to which the float is attached drops down and the mercury
switch, which is attached to the pivot point on the lever rod, tilts
forward. This action causes the mercury switch to close and turn on the
light on the indicator panel.
The Low Level Indicator is an optional feature which may be either
purchased with the applicator or added at a later date. It may be
obtained with a kit which will permit the warning to be displayed (or
sounded) remotely.
