The WeighBar®, and How it Works.

Weigh Bar Image Avery Weigh-Tronix pioneered electronic farm and industry scale technology with the introduction of the Weigh Bar more than 40 years ago. Since that time, the WeighBar has proven to be the most reliable and long-lived electronic weight sensor in the industry. It is virtually unaffected by wear, every day jolts, weather and other normal environmental hazards.

Weigh Bar


The WeighBar is fixed at one end and flexes under an applied load. Strain gauges on the bar transform this physical change into voltage variations. A digital indicator translates these variations into highly precise weight readings. The WeighBar doesn't rely on perfect installation to be accurate, and is not in need of constant tweaking in order to perform. The self-correcting design of the WeighBar cancels out distortions so only the vertically applied load is measured.

A compact readout on the new Multi-Purpose Scale from Central City Scale can be bolted to the dash of a pickup cab. The multipurpose, 5,000-lb. scale system runs on 12v DC or 110v AC power. The load cells act as bolt-on feet to fit under the four corners of the unit, deck or platform. The scale system could be used in cattle-working chutes or at livestock platforms.

Truck Platform Scale

WeighBar® Truck Scales

An on-farm or in-plant  truck scale will save you money in several ways.  You can verify incoming delivery weights, pre-check load weights going out to the elevator, or check grain yields to compare the performance of different seeds, fields or fertilizers.  Plus, you'll no longer have to worry about picking up a traffic ticket for an overloaded truck.

A truck scale WeighBar kit consists of four or eight WeighBars with cables and brackets.  (Indicators sold separately). Additional construction materials can be purchased locally. A full checklist of materials needed to build your own economical farm or plant weighing system is available at your request.

Small Animal Platform Scales

Animal & Platform Scales

Building your own scale allows you the flexibility to design it to fit your situation best.

You can turn an existing pen into a livestock scale simply by bolting four WeighBars under it and connecting them to an indicator. Your livestock scale can be large enough for a group of animals or it can be built for a single animal.  You can put in an alleyway or a loading area. Selectable motion filtering is available in Avery Weigh-Tronix indicators so you don't have to worry about livestock moving around on the scale.

A platform scale is one of the easiest scales to build.  You can build a low capacity platform scale for weighing carts of feed or a higher capacity scale for weighing wagons or single axles.
