Load Cell Scales and Weighing Sensors

Strain gauge load cells contain a resistive element bonded to a structural member that deforms slightly under load. This deformation changes the electrical resistance, which is measured and converted into a weight value. Air suspension sensors instead measure air pressure changes in the suspension bags to calculate weight.

A weight scale is the complete system that displays a weight reading, including sensors, wiring, and a readout device. A load cell is just the sensor component within that system responsible for detecting force and converting it into an electrical signal that the scale's display or analytics software interprets.

Pricing varies by sensor type and suspension compatibility. Strain gauge sensors for spring and mechanical suspensions typically range from $699 to $799, while air suspension sensors are quoted on request based on vehicle configuration and volume, so contacting the manufacturer directly is recommended for accurate pricing.

Common load cell types include strain gauge (mechanical), hydraulic, pneumatic, and capacitive designs. In onboard truck weighing, strain gauge sensors are used for spring and mechanical suspensions, while specialized pressure-based sensors are used for air-ride suspensions, each suited to different vehicle and application needs.

Yes, many onboard weighing sensors feature transferable calibration data, allowing the system to be moved from one truck to another without requiring a full recalibration process. This reduces downtime and installation costs when reassigning weighing equipment across a fleet.

Accuracy depends on sensor type and suspension. Strain gauge sensors typically measure within 0.3-2% of gross vehicle weight, while patented air suspension sensors achieve 0.3-1% accuracy across varying weather conditions, providing reliable payload data for compliance and load optimization purposes.
