Shear Beam Load Cells

Shear beam load cells for tank, silo, and floor scales

A shear beam does not measure the bending of the spring element but the shear stress in its cross-section. This makes the design largely insensitive to the exact point of load application and to side forces – the reason why shear beams are the standard solution in multi-cell systems.

• Nominal loads from 50 kg to 10 t, covering the classic range for tank, silo, and platform scales
• Versions in 17-4PH or AISI 420 stainless steel or nickel-plated AISI 4340 steel, hermetically welded
• Protection ratings IP67 and IP68, individual designs up to IP69k for high-pressure cleaning
• Accuracy class C3 to OIML R60 for legal-for-trade applications, combined error down to ≤ ±0.02 %
• Versions with ATEX and IECEx approval as well as one version with a digital IO-Link output

Matched outputs for multi-cell systems

For scales with three, four, or more support points, cells with matched output signals are available. Safe load introduction with tilt and lift-off protection is handled by matching weighing modules.

Related designs: bending beam load cells for smaller nominal loads, double-ended shear beam load cells for heavy loads, and platform load cells for compact single platforms. Signal processing is handled by devices from our measuring electronics range; on request we calibrate to ISO 17025 in our own laboratory.
