Introduction
The TuffSeal
®
series are excitation or signal trim junction boxes that can
accommodate two, three or four load cells. Primarily used in floor and hopper scales,
each model also has the capability to extend to more than four load cells using an
excitation connector.
All models have a new Prevent
®
breather vent, which inhibits the buildup of pressure
caused by sudden temperature or environmental changes. It must be changed every
six months to a year, it does become dirty over time. When correctly installed and
torqued to 10 lb/in, all models can withstand 900 PSI water pressure.
All terminals will function properly without modification. However, load cell output can
be individually trimmed with potentiometers which is further explained in
of this manual.
The TuffSeal manual, part number 91909, has been updated to 184803
effective July 24, 2017.
