Weigh BarĀ® Weight Sensor
Our industry leading technology, the Avery Weigh-Tronix
Weigh Bar, was born on the farm and is specifically
designed to withstand the tough conditions of the
farm environment. Environmental seals and coatings
protect against rain, snow, dust and mud. Weigh Bars are
engineered using Finite Element Analysis (FEA) and constructed
to handle the toughest jobs. All these features add up to
years of precise, trouble-free operation.
Agricultural weighing applications are often mobile and in harsh and uneven conditions. Click here to see how the Weigh Bar design handles End Loading, Side
loading and Torsion better than other weigh solutions.

Pre-calibrated
All our Weigh-Bars are
pre-calibrated. When used with Avery Weigh-
Tronix indicators, no test weights are required so
accurate weighing is obtained straight out of the
box.

Design
The Avery Weigh-Tronix team of engineers is fully
equipped with the most up-to-date development
tools such as Finite Element Analysis (FEA) and
Computer Aided Drafting (CAD). Our expertise
and attention to detail add up to years of durable,
trouble-free operation. All our Weigh-Bars are
pre-calibrated. When used with Avery Weigh-
Tronix indicators, no test weights are required so
accurate weighing is obtained straight out of the
box.

Construction
The Weigh Bar is
machined from high quality
alloy steel in our modern machine shop.
After the machined bar has been thoroughly
cleaned, strain gages are applied in a controlled
environment using an epoxy which is then oven
cured. Interconnect wires,
and the scale interface cable is
then professionally soldered to the
gages. The gages and solder joints are then
completely sealed with an aerospace- developed
sealant. After the bar passes a series of tests, a
steel shield is slid over the entire gage area on
all bending beams and completely filled with
a potting compound to provide rugged, long
lasting protection against the elements. Other
companies have built copycats, but the Weigh
Bar remains unmatched in terms of accuracy,
reliability, and performance under difficult
agricultural conditions.
Quality
All Avery Weigh-Tronix agricultural products are
backed by a minimum 3 year warranty. Avery
Weigh-Tronix is ISO-9001 certified and performs
regular audits of the established standards. All
Weigh-Bars are individually tested to our specified
standards during final assembly.
