定义
A specialized sealing component designed for load cells that creates a hermetic or environmental barrier between the strain gauge assembly and external conditions. It prevents ingress of moisture, dust, chemicals, and particulates while maintaining the structural integrity and measurement precision of the load cell under varying operational stresses.
工作原理
Utilizes compression sealing or bonded sealing techniques to create a continuous barrier around load cell elements. The seal maintains constant contact pressure through elastic deformation or adhesive bonding, preventing contaminant migration while accommodating minor thermal expansion and mechanical deflections without compromising the load cell's strain measurement capabilities.
材料
Food-grade silicone rubber (FDA 21 CFR 177.2600)fluorosilicone (FVMQ)ethylene propylene diene monomer (EPDM)or polyurethane with hardness 50-80 Shore A. Temperature range: -40°C to +150°C. Chemical resistance specified per ASTM D471.
IP Rating
IP67/IP68
Tear Strength
≥30 kN/m (ASTM D624)
Compression Set
≤20% (ASTM D395)
Compression Force
5-20 N/mm
Temperature Range
-40°C to +150°C
Operating Pressure
0-2 bar
标准
ISO 3601-1DIN 3770ASTM D2000ISO 6194

常见问题

What is the primary function of a load cell sealing component?

The primary function is to protect the sensitive strain gauge elements from environmental contaminants like moisture, dust, and chemicals while maintaining measurement accuracy and extending the load cell's operational lifespan.

How often should load cell seals be inspected or replaced?

Inspect seals during routine maintenance (typically every 6-12 months) and replace immediately if visible damage, compression set exceeding 25%, or measurement drift is detected. Harsh environments may require more frequent inspection.

Can load cell seals be customized for specific applications?

Yes, seals can be customized for material composition, dimensions, temperature ranges, and chemical resistance to match specific industrial environments and compliance requirements.
