Bench Platform Balance

What is the Bench Platform Balance?

A bench platform balance has a platform of about 300 by 400 mm to 400 by 500 mm and capacities from 6 to 60 kg, placed on a workbench. It weighs larger vessels, packages and samples that exceed precision balance capacity.

Overview

The bench platform balance is the compact member of the family, used on a laboratory bench or table. Platforms are typically 300 by 400 mm to 400 by 500 mm in stainless steel or painted steel, resting on one load cell or four with a junction box. Capacities of 6, 15, 30 and 60 kg are common, with divisions of 0.1 g to 5 g, giving 3,000 to 30,000 divisions. The indicator is built into the base or mounted on a column and shows weight, tare and unit, with backlit LCD or LED. Functions include counting, percent weighing and checkweighing with color indication. Overload protection is 150 percent. Batteries of 50 to 100 hours allow portable use. The unit is light enough to move, and bench placement suits repeated weighing of buckets, bottles and cartons.

How does it work?

Platform balances use strain-gauge load cells. Each cell contains a metal spring element, such as aluminum or stainless steel, bonded with resistive strain gauges in a Wheatstone bridge. Load on the platform deforms the element, changing gauge resistance and producing a small voltage proportional to force. One to four cells support the platform, and a junction box sums their signals. The indicator amplifies and digitizes the signal, corrects for temperature and non-linearity, and displays mass. Overload stops protect the cells from shock, and a steel or stainless platform spreads the load. Calibration uses certified test weights, and corner-load adjustment compensates for off-center placement. Indicators may be attached by cable or wireless link and offer functions such as tare, counting, checkweighing and totalizing.

What are the key features?

• Stainless steel or painted platform of 300 × 400 to 400 × 500 mm
• Capacities from 6 to 60 kg with 3,000 to 30,000 divisions
• Counting, percent and checkweighing modes with color indicators
• Rechargeable battery of 50 to 100 hours for portable use
• Overload protection of 150 percent of capacity

What are the technical specifications?

A typical bench platform balance configuration offers capacity of 6–60 kg, readability of 0.1 g–5 g, platform size of 300 × 400 to 400 × 500 mm, platform material of Stainless steel or painted steel, linearity of ±1–2 divisions and overload protection of 150% of capacity. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Bench Platform Balance is used in weighing buckets and bottles, incoming material checks, packaging checkweighing and parts counting. Across the wider Platform Balances class, laboratories also deploy it for drum and container weighing, bulk material batching and incoming goods inspection.

Which standards and certifications apply?

Relevant standards and methods include OIML R 76-1, OIML R 60, EN 45501, IEC 60079-0, IEC 61010-1, GB/T 7724 and ISO 9001. Certification candidates for this model are CE, ISO 9001 manufacturing and OIML R 76 type approval; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Install on a flat, rigid floor or solid bench, and adjust feet until the platform sits evenly on every support. Avoid placing the scale where forklifts, vibrations or drafts disturb readings. Calibrate on site with certified test weights, ideally around 50 to 100 percent of capacity, and check corner loading. Protect cables from damage and moisture, and use junction boxes with appropriate ingress protection. Do not overload or drop heavy items on the platform, since shocks damage load cells. Inspect feet, cells and cables at regular intervals, and clean under the platform to prevent debris from blocking movement. For trade or regulated use, verification by the competent authority and sealing are required.

How do I select the right Bench Platform Balance?

Select a bench platform balance for loads from 6 to 60 kg on a workbench. It is easier to move and cheaper than floor models. In the RFQ, specify capacity, division, platform size and material, battery need, and indicator functions.

How does it compare with other Platform Balances variants?

Begin with the heaviest load including the container, then select a capacity about 20 to 30 percent above it, and pick a readability that gives at least 3,000 divisions for general use. Platform size should fit the largest vessel or pallet with margin. Choose material by environment: painted carbon steel for dry areas, stainless steel for wet or corrosive areas. Consider hazardous-area certification if flammable solvents are present, and ingress protection for washdown. Check the indicator functions such as checkweighing, counting and data output, and whether wireless or remote display is needed. For trade use, confirm legal-for-trade approval. Finally, confirm access, such as a ramp for floor models, and overload capacity for drum handling.
