The Importance of Accuracy in the Weighing Process

A weighing process is used in many industries to measure and control the mass of a material or product. It can be critical to quality control and overall profitability in the manufacturing environment.

A weighing process can be as simple as weighing a sample and displaying the result, or as complex as dispensing a weighed quantity of material into a container. In either case, the weighing process should be accurate and repeatable.


Accuracy is the ability of a weighing process to produce results that are as close as possible to an actual value. Accuracy is usually measured against a standard value such as a kilogram or pound, though it can also be based on other factors, such as repeatability and precision.

To be accurate, a weighing system must use top-quality load cells and weight controllers. They must be hermetically sealed at the strain gauge area and the cable entry.

Load cells convert applied load into a proportional electrical signal that is communicated to the weight controller. The weight controller converts that signal into digital form, which is displayed on the scale.


There are a number of factors that can cause errors in the weighing process. These include the load cells themselves, environmental conditions and a range of other forces that can affect the performance of the weighing system.

Load cells are vital components of a weighing system as they take the mechanical force from the weight applied to them and convert this into an electronic signal. This then gets transmitted to a controller that converts this into a digital measurement.

The output of these load cells is impacted by temperature changes. These can result in error readings, so it’s important to recalibrate your load cells when there are large temperature changes between the weighing sessions.

Pressure differentials can also affect a weighing system’s accuracy. For example, if you have a weigh vessel installed between two floors in a pressurized plant, the load cell outputs may not be consistent with the floor’s constant pressure level.

Electrical noises, such as RFI and EMI, can also have an impact on the weighing system. This can be minimised by shielding the electrical signals that travel from your weighing system to the display.

Measurement Methods

Weighing is a common laboratory procedure, used to measure the quantity of a chemical substance or sample. It is a critical part of any analytical determination because the weight of a sample can determine its identity, properties, purity and quality.

To ensure accurate weighing, follow proper methods and practices. For example, never use a non-tared container to weigh a sample; only a tared container is allowed on an analytical balance.

Another important tip is to tare an analytical balance before using it for the first time. This will remove built-in weights that will interfere with the accuracy of the weighing process.

Calibration of a balance is the most important step in achieving accurate measurement results. This involves comparing the displayed value on a balance with an accepted standard or true value that falls within an assigned measurement uncertainty range.


Calibration of the weighing process is important to ensure that you receive accurate results. It also allows you to avoid fines and legal action, and ensures that your weighing equipment is in compliance with essential regulations.

Calibration involves comparing the measuring device to an equal or better standard. This can be an external standard (such as a dead weight tester or other measuring device), or an internal standard, such as a weight that is placed on the scale and whose reading is used to determine the accuracy of the scale.

Typically, calibration is performed by a laboratory accredited to the international standard ISO 17025. This standard requires that the laboratory has a quality management system and technical competence, and that it is impartial in its work.

The frequency of calibration varies depending on the type and size of the device being calibrated. Generally, a small, portable instrument will require annual calibration, while a large, industrial-grade weighing scale may need monthly or quarterly calibrations.

Best Ways to Control Weight

control weight

Weight control involves many factors, including eating a healthy diet and exercising regularly. Once you’ve reached your goal weight, maintaining it requires discipline and commitment.

Research shows that exercise can help you suppress your appetite. This is likely because exercise increases body temperature and triggers a system that controls appetite.

Eat a Healthy Diet

A healthy diet can help you control your weight and keep you feeling good. It should include a variety of nutrient-dense foods from all major food groups, such as vegetables, fruits, whole grains and healthful fats.

A balanced diet can also help you avoid or control chronic noncommunicable diseases such as heart disease, diabetes and cancer. It is essential to limit salt and sugar intake.

Another important element of a healthy diet is to cut down on highly processed foods. These are often full of sugars, trans fats and unhealthy fats.

Choosing whole foods, such as fruits and vegetables, can reduce your intake of calories and salt. Likewise, replacing soda with water or milk can reduce your intake of sodium and saturated fats.

Exercise Regularly

If you are overweight, exercise regularly is the best way to control weight. It not only helps you lose weight, it also prevents several chronic diseases and boosts your mood, energy, self-esteem, sleep quality, and strength.

In addition, exercise improves brain health and reduces the risk of dementia. It increases blood flow and oxygen to the brain and releases chemicals that enhance memory and learning.

Getting the recommended amount of aerobic activity (150 minutes per week, or 75 minutes of vigorous aerobic activity) will help you get the most benefits from exercise. To gain even more health benefit, add stretching and strengthening exercises to your routine.

It is important to find physical activities that you enjoy. Choosing an exercise that you are interested in will help keep you motivated and prevent boredom.

Get Enough Sleep

You may already know that getting enough sleep is essential to health, but it’s also critical for controlling your weight. Studies show that adults need 7-9 hours of sleep per night to function properly, and those who don’t get enough sleep are more likely to be overweight or obese.

Even a few nights of poor sleep can have a devastating effect on your body’s hormones and metabolism, including the amount of insulin you produce, which leads to high blood sugar levels.

Insufficient sleep can also affect the production of appetite-regulating hormones, like ghrelin and leptin. Lower levels of ghrelin cause hunger, while higher leptin levels make you feel full.

The good news is that you can control these factors with just a few extra hours of sleep. Researchers have shown that by simply adding an additional four hours of sleep to your routine, you can lose up to 300 calories a day.

Stay Active

One of the best ways to control your weight is to be physically active. A daily regimen of walking, dancing, briskly biking, or a mix of the two may be all it takes to keep you fit and healthy. Not only will you look good and feel great, but being more active will also lower your risk for heart disease, diabetes, high blood pressure, and osteoporosis.

The best part? Unlike other diet related activities, it’s easy to maintain an active lifestyle. The secret is to make exercise a natural part of your day and incorporate it into everyday activities like housework, shopping, and driving. As a result, you’ll be more likely to find yourself on the right track to your dream body. Getting the most from your activity will require some planning and preparation, but it will be worth the effort. The most important thing to remember is that it all starts with you. Your health is your top priority, so make sure that you are taking advantage of the many opportunities that are presented to you each and every day.
