1. Introduction
The TuffSeal
®
junction boxes are excitation or signal trim junction boxes that can
accomodate two, three, or four load cells and are used primarily in fl oor and hop-
per scales. Each model also has the capability to extend to more than four load
cells using an expansion connector. All models have a new Prevent
®
breather vent.
The breather vent inhibits the buildup of pressure caused by sudden temperature
or en vi ron men tal changes and should be changed every six months to one year as
it will become dirty over time. When correctly in stalled, all models can withstand
900 PSI water pressure.
All terminals will function properly without mod i fi ca tion. How ev er, load cell
output can be in di vid u al ly trimmed with po ten ti om e ters which is further explained
in Section 4.0.
Model Designations

steel for the small junction box and a FRP enclosure for the mid-range junction
box. Ap pli ca tions vary from use in fl oor scales to hoppers so selection can vary
from a light capacity junction box to a mid-range capacity junction box. TuffSeal
models include:
