Precision scales | OMEGA Waagen GmbH

Within the table scales there are also the fine scales. The term is often misused for SEO reasons. Fine balances are pending according to DIN EN 45501 of accuracy class I. Precision scales are found in class II of the same standard. However, since fine balances are searched for more often, the use of the wrong term is common.

The precision scales from OMEGA Waagen GmbH offer many possible uses. With weighing capacities up to 3.2 kg and a readability of 10 mg, they meet even the highest demands on functionality and repeatability.

Application

Precision scales, or correctly precision balances, are assigned to Class II and achieve verification values of at least 100 or 5,000 and at most 100,000 according to DIN EN 45501. The areas of application are mainly in quality assurance and laboratories.

Fine balances are also used for determining the weight of gold, precious stones and other materials where the highest accuracy is required. Whenever a few grams or milligrams are decisive, a precision balance is the right choice.

class subdivision scales

Scales are divided into 4 classes according to DIN EN 45501. A distinction is made according to the following table

Accuray class

Calibraion value

Minimum load

Fine balance (I)

0,001 g

100 e

Precision balance (II)

0,1 g

50 e

Commercical scale  (III)

0,1 g

20 e

Coarse balance  (IIII)

5 g

10 e

 

The table is not complete in this way, but provides a good overview. Exact information about the calibration classes are in our blog.

overview of fine balances

Our precision scales convince through excellent workmanship. The resolution is made possible by the precise load cell and well thought-out load handling. An air protection that can be opened on both sides and on top creates a basis for accurate and reproducible weighing results.

Practically all manufacturers use English designations for keyboard labelling. Certainly a basically good solution for the European and international market. We focus on comprehensibility and label our keyboards in the local language. Another step towards perfection.

The fine balance is characterized by a very fast reaction time. An RS-232 interface is provided as standard and enables data transfer to a printer or PC. The display is backlit and therefore easy to read. Mobile use is possible with the battery included in the scope of delivery.

Under the stainless steel load carrier is the well thought-out load support. This, in conjunction with the high precision Single Point load cell, allows precise results to be obtained even under off-center loads. Reproducibility is a basic requirement for reliable weighing results. This is also achieved by the well thought-out design and the use of high-quality components.

installation and use

When using a precision scale, make sure that no external influences influence the weighing result. Even a draft can have a significant impact at such a high resolution. The draft shield prevents this influence and ensures correct results.

When setting up the balance, please note that vibrations can distort the weighing result or lead to an extended settling time. A fine balance must be placed in such a way that no vibrations act directly or indirectly on it. A decoupling with a weighing table is a fast and cost-effective solution. The weighing table consists of a steel frame base frame on which a granite plate is mounted.

With our mobile solution, the fine balance can also be operated in a changing application area. The rollers are well dimensioned and allow easy transport of the antivibration table. Our precision scales can also be operated by a rechargeable battery. This is of course a prerequisite for mobile use.

If all installation requirements have been observed, there is nothing to prevent accurate weighing. The scale is delivered fully calibrated and can be used immediately. In some applications a certificate of calibration is required.

certificates of calibration

If the quality management system of a company is certified, a measuring equipment monitoring system must be established. All measuring instruments are listed in the measuring equipment list to be maintained. The status of the calibration must also be recorded. Depending on the QM system, the type of documentation on calibration must be determined:

·   Calibration
 When the balance is used legal metrology

(e.g. when sold by weight)

 

·   ISO – Calibration certificate

If the company is certified according to DIN EN ISO 9901

·   DAkkS – Calibration

If anISO TS QM system is established, a DAkkS calibration be undertaken

If a verification or calibration is ordered, the protocol is enclosed with the delivery. This will also be transmitted to the customer by e-mail.

On request, we can also take over the monitoring of measuring equipment for you. Simply inform us about already existing measuring equipment and we will keep the list of measuring equipment. This is available for you to view at any time. Upcoming tests will be carried out by us in due time after the order has been placed. We will inform you in good time before the expiry date and carry out the test on request.

connection options

The standard RS 232 interface allows the connection of a printer from our product range. The values determined can be printed out quickly and effectively and thus documented. Transmission errors are thus minimized. It is also possible to transmit the weighing data to a PC via this interface. The data format can be taken from the operating instructions. With this protocol the implementation of the data in the customer software is unproblematic and can be implemented on site with little effort.

Material

The high quality plastic housing is easy to clean. The modern design blends beautifully into any laboratory environment. The stainless steel load support reflects the continuous quality concept. Instead of plastic, we use glass for the windscreen, which can be opened on both sides and at the top.

In a clean room this can be dispensed with if the ambient conditions are suitable. The frame can be dismantled quickly and easily for this purpose.

 Power supply

The scope of delivery includes a power supply unit with which the scale can be operated directly from the mains. Optionally the use with a rechargeable battery is also possible. This is charged via the plug-in power supply unit and the operation is carried out via the rechargeable battery. The power saving function switches off the backlight of the display after a few seconds to allow a longer runtime. This function can also be deactivated by the user.

Contact to us

Please contact us for individual advice on your specific application. The highly qualified sales staff is supported by all other departments. In this way we can competently process your inquiries and achieve excellent results.

Our design department works with the latest CAD technology and in the first step creates a 3D model of your custom-made product. From this we then develop the perfect scale for your application together with you.
