A gravimeter is a scale used to weigh agricultural products.
Most scales are made of stainless steel, which is resistant to rust even when wet or dusty, and easy to wash off. Large gravimeters are designed to withstand rain and wind, as they are sometimes stored outside.
The maximum load varies greatly depending on the specifications, ranging from a few kilograms to several hundred kilograms. Some products have a sorting function that provides audible assistance in sorting according to the set weight.
Gravimeters are used to weigh harvested crops and sort them by weight for shipping. They can be used for any type of produce, as long as the gravimeters have the appropriate specifications for the weight of the produce.
For sorting by weight, a box containing the crops is placed on the gravimeters, and the weight of the crops taken from the box is used to determine the weight.
The table scale type is a gravimeter that measures the weight of an object to be weighed by placing it on a table. It can be used for a wide range of crops, from small to large crops.
Since this type is relatively large, it is necessary to consider the installation location before purchasing. Recently, however, foldable products that can be stored compactly are also available.
The upper pan scale types are gravimeters that measure the weight by placing the object to be weighed on the upper weighing pan. There are analog and digital types, and analog types have been used when there is concern about water damage.
In addition, some digital gravimeters are equipped with a wireless communication function that enables historical management of weighing results, while others are dustproof.
The U-shaped type gravimeters use a hand-held pallet as a weighing pan. It is mainly used to measure pallets loaded with many products, such as rice bags. They are thinner than other types and can be stored in a space-saving manner by storing them upright.
A hanging scale is a gravimeter that measures the mass of an object to be weighed by hanging it in midair. A controller with a display allows you to check the mass at hand while operating the scale. It is mainly used to measure crops stored in flexible container bags, such as rice husks and corn.
Various other gravimeters are also available for different applications, such as gravimeters that come with a weighing platform and cart, and wheelbarrow scales that can be attached to and detached from standard containers.
The weighing range refers to the range of weights that can be weighed. Some scales can weigh only a few kilograms, while others can weigh up to several hundred kilograms, depending on the type.
The minimum display unit is the smallest weight that can be read. Some gravimeters can read down to 0.01 kg, while others cannot read less than a kilogram.
Some gravimeters are required to be used for proof of transaction when agricultural products are sold by weight. If you want to use them for weighing and selling, it is important to choose one of the transaction-proof gravimeters.
The Measurement Law requires that gravimeters used for transaction proof be brought to a location designated by the nearest municipality every two years to undergo periodic inspections.
Gravimeters can be used to confirm the weight of agricultural products. Therefore, gravimeters are useful for pre-shipment sorting.
Also, by using the right gravimeters for the right situation, it is possible to measure the weight of agricultural products more efficiently.
Since different types of gravimeters have different functions, they may not have all the functions you need if you make a mistake in selecting the right one. It is also important to check the functions and storage location of gravimeters before using them.
