What Is a Gravimeter?
A gravimeter is a specialized scale used in agriculture to weigh harvested crops. Typically made of stainless steel for rust resistance and easy cleaning, these scales can vary significantly in their maximum load capacity, ranging from a few kilograms to several hundred kilograms. Some models include a sorting function that assists in categorizing produce by weight.
Uses of Gravimeters
Gravimeters are employed for weighing and sorting agricultural produce by weight, making them versatile for various types of crops, as long as the scale specifications match the produce's weight. They are often used in combination with a box to hold the crops during the weighing process.
Types of Gravimeters
1. Platform Scale Type
Platform scales are commonly used for a wide range of crops and feature a table where items are placed for weighing. Consider the installation location due to their size. There are also foldable models for compact storage.
2. Upper Pan Weigher Type
This type places the item on an upper weighing pan and is available in both analog and digital forms. The digital models may offer wireless communication for managing weighing data and are often dustproof.
3. U-Shape Type
U-shaped gravimeters use a hand-held pallet as a weighing pan, ideal for measuring large quantities of products like rice bags. These models are slim and space-saving.
4. Hanging Scales
Hanging scales measure the mass of items suspended in midair, useful for crops stored in flexible container bags like rice husks and corn. They often come with a controller and display for easy operation.
How to Select a Gravimeters
1. Weighing Range
Choose a gravimeter based on the range of weights it can measure, from light to heavy loads.
2. Minimum Display Unit
Consider the smallest weight increment the gravimeter can display, which varies among different models.
3. Transaction Proof
If the gravimeter is to be used for selling crops by weight, ensure it is certified for transaction proof and undergoes regular inspections as required by the Measurement Law.
Characteristics of Gravimeters
Advantages
Gravimeters aid in accurately determining the weight of agricultural products, facilitating efficient pre-shipment sorting. By selecting an appropriate gravimeter for specific needs, weight measurement becomes more efficient.
Disadvantages
Selecting the wrong type of gravimeter may result in missing necessary functions. It's important to check the features and storage requirements before use.
Other Information on Gravimeters
Functions of Gravimeters
Gravimeters come with various functionalities, such as:
- Unit Price Calculation: Calculates the price of products based on weight.
- Total Amount Calculation: Computes the total value of multiple items.
- Tare Function: Deducts the weight of packaging materials to measure the net weight of the crop.
- Rank Sorting: Allows detailed sorting by pre-setting weight categories.
- Voice Function: Announces the measured weight and rank, enhancing work efficiency.
