Weighing of commodities has to be done at various stages of production on the farm. At the sowing stage, seeds, chemicals, and fertilisers have to be weighed, and after harvest, the quantity produced has to be assessed.  Weighbridges must be selected based on application, requirements, space, and the soil quality of the region. 

Depending on the type of commodities to be weighed and the maximum load expected to be weighed, appropriate weighbridges can be chosen for agricultural operations. Other considerations include vehicle weight and frequency of use. 

  1. Concrete Weighbridges: Concrete weighbridges are meant to be installed permanently on the ground. If the weighing requirements are high, concrete weighbridges may be appropriate. Such weighbridges are installed by digging a pit and laying a foundation using reinforced concrete for the platform. 
  2. Steel Weighbridges: Steel weighbridges are durable and can be set up in a pit or on the surface, depending on the space availability. Anti-corrosion protection is provided for steel weighbridges. Steel weighbridges are pre-fabricated and installed onsite. Unlike steel weighbridges, they can be dismantled and taken to a new location. For pit-type weighbridges, the platform is level with the ground. This makes it easier for the vehicle to enter and level the platform. For pitless weighbridges, a ramp is set up for the entry and exit of vehicles. 
  3. Silo Weighing Systems: Silo weighing systems have applications in agri-processing and plantations. They consist of bins/hoppers or a silo with varying weighing capacities. They are equipped with load cells and network connectivity for transmitting data to the computer system. 
  4. Weigh Pads: Weigh pads are suited for temporary installations. It is used to weigh the individual axles to calculate the aggregate.

Features to Consider

The accuracy of the weighing depends on the sensor or load cell. Regular calibration must be undertaken to ensure the accuracy of weighing.

Legal Compliance

Ensure that weighbridges are compliant with the standards set by the legal metrology department and suitable for industrial use.  

Support and Service

A weighbridge manufacturer who provides installation, calibration, and maintenance support must be chosen. Closely check their warranty terms and availability of spare parts.
