Recommendation for 0.001g / 0.01g Electronic Balances: Why Mettler Toledo and Ohaus Rely on Pressure Sensors?

BDSCALES leverages years of industry experience to tell you: the old mindset that high precision strictly requires electromagnetic force restoration is long outdated!

Looking at today's tier-one international brands—such as Mettler Toledo, Japan's A&D, and USA's Ohaus—they have long adopted high-precision strain gauge load cells in their precision balances. In fact, Ohaus has made load-cell-based electronic balances a core flagship product line.

1. 0.001g / 200g (1mg Milligram Weighing Balances)

• Traditional Misconception: Industry professionals once believed 0.001g weighing accuracy could only be achieved with expensive electromagnetic force balances.
• Current Industry Reality: For standard capacities like 200g, the repeatability (measurement stability when repeatedly weighing the same item) of modern top-tier load cells is completely reliable. Brands like A&D and Ohaus offer highly mature load cell balance products in this exact specification.
• Core Technical Reason: Leading brands like BDSCALES utilize high-resolution A/D conversion chips combined with intelligent digital filtering algorithms. This keeps the last decimal digit (0.001g) rock-solid, directly shattering the technical myth that "strain gauges cannot handle milligram-level weighing."

2. 0.01g / Capacity Below 1200g (Precision Balances)

• Current Industry Reality: In this specification range, almost no manufacturer insists on using electromagnetic force restoration anymore. Even global industry giants like Mettler Toledo with their classic PL Series, as well as Ohaus’s mainstream precision balances, Pressure Sensors technology across this entire range.
• Why Abandon Electromagnetic Force? ：The large internal permanent magnets and precision coils required for electromagnetic force sensors carry extremely high manufacturing costs, multiplying the retail price. Furthermore, their internal flexures are exceptionally delicate and easily damaged by impacts on production lines.
• Advantages of Pressure Sensors: Factory-calibrated multi-point temperature compensation algorithms eliminate measurement drift caused by thermal expansion and contraction. Pressure sensor balances deliver identical precision at merely one-third the cost, with superior vibration resistance—making premium electromagnetic force balances an unnecessary expense for most users.

3. 0.1g / Capacity Below 8000g (Large Capacity Precision Scales)

• Industry Consensus: Electromagnetic force sensors are virtually never used in the market for high-capacity balances up to 8 kg.

• Why Avoid Electromagnetic Force?: Supporting weights up to 8 kg with electromagnetic force requires passing massive electric currents through internal coils. The resulting thermal effect causes severe heat drift, making it technically counterproductive.
• Strengths of Pressure Sensors: Single-point strain gauge load cells are inherently ideal for large weighing capacities. Built with solid metal bodies, they boast exceptional durability. Paired with software filtering algorithms, they output precise readings instantly even in noisy, vibration-prone environments such as manufacturing workshops and logistics packaging stations.

4.Conclusion & Brand Commitment

When choosing a balance today, focus not on marketing buzzwords regarding working principles, but on "reliable precision & stability, robust shock-resistant durability, and cost-effectiveness "  

Global industry leaders from Mettler Toledo and A&D to pressure-sensor-focused Ohaus have already proven the superior performance of high-precision pressure sensors. Equipped with unmatched price competitiveness, cutting-edge chip algorithms and outstanding structural durability, pressure sensor weighing technology has fully replaced electromagnetic force modules across the 0.001g to 0.1g precision weighing spectrum （Note: The core materials of electromagnetic force sensors are extremely expensive due to high-purity rare-earth permanent magnets and precision copper coil wire).

BDSCALES focuses on precision measurement. By breaking industry hyper-profits through advanced manufacturing, we provide you with weighing solutions that match international brand accuracy at significantly higher cost-efficiency.
