Why replace when you can retrofit? These kits use WeighBar® load cells and durable indicators to build a custom truck scale, update an old conventional platform, or add weighing to bins and hoppers. They suit farms, manufacturing and agribusiness.
Why retrofit
- Save thousands: skip a full scale replacement and reuse your existing platform or structure.
- Proven in harsh conditions: indicators are water- and dust-resistant, tested on farms, with a 3-year warranty.
- Flexible: Weigh Bars connect directly to indicators (12 VDC power). Optional RS-232 ports, and Bluetooth on select models, link to printers, computers, batching systems or mobile apps.
- Weigh where you need it: verify incoming deliveries, check outgoing loads, monitor grain yields, avoid overload fines and compare field or seed performance.
- Do it yourself or have it installed: few tools needed, and you can source local materials for custom builds.
Kit options
WeighBar® truck scale kits
Build your own on-farm or in-plant truck scale. Kits include 4 or 8 WeighBars, cables and mounting brackets. Indicators are sold separately. Use it to check truck weights, avoid tickets and haul accurate loads.
Universal Kit: digital scale conversion
Put new electronics in an old conventional platform scale. Order detailed plans for standard sizes, then add indicators, power supplies, sensors and brackets to your specs.
WeighBar bin and hopper scale kits (Avery Weigh-Tronix compatible)
Weigh dry or liquid material right in the bin, hopper or tank, with no hauling to a separate scale. Set WeighBars under the legs, level them, bolt them down and connect an indicator. They interface with batching systems for full data management.
Indicators
Pair your kit with an indicator such as the 660 or the Libra, for TMR mixers, grain carts, livestock platforms, feed bins and more. All models have:
- Dust and water resistance
- 12 VDC operation
- Optional serial output, plus Bluetooth, for data logging and apps
- Large, bright, color-changing display
- 3-year warranty
