Frequently Asked Questions
How do on-board truck scales for air suspension work?
On-board scales for air suspension typically measure the air pressure within the truck’s air suspension bags. As weight is added to the truck or trailer, the air pressure in the bags increases. The scale system then uses pre-programmed calibration data to convert these pressure readings into an estimated weight for individual axles or axle groups, and often the gross vehicle weight.
Are on-board scales accurate enough for legal compliance?
Based on manufacturer specifications and aggregated owner feedback, many high-quality on-board scales, especially those with proper calibration and maintenance, can provide accuracy within a few hundred pounds, which is often sufficient for preventing significant overloads and avoiding roadside fines. However, for precise legal weight certification, a certified weigh station should always be used as the final verification. On-board scales are best utilized for pre-trip checks and load adjustments.
What factors affect the accuracy of an on-board air suspension scale?
Several factors can influence accuracy, including proper initial calibration, ambient temperature fluctuations, tire pressure, the condition of the air suspension system, and even the levelness of the ground where the reading is taken. Regular re-calibration, especially after significant changes to the truck or trailer, is crucial for maintaining optimal accuracy.
Can I install an on-board scale myself?
While some simpler on-board scales are designed for DIY installation with clear instructions, many advanced systems, particularly those requiring integration with multiple air lines or complex electrical systems, often benefit from professional installation. Improper installation can lead to inaccurate readings or damage to the system. Always refer to the manufacturer’s installation guide and consider professional help if you are unsure.
What is the difference between an on-board scale for air suspension and a traditional load cell scale?
On-board scales for air suspension utilize pressure sensors in the air bags to estimate weight, making them generally easier to install as they integrate with existing systems. Traditional load cell scales, conversely, use strain gauges directly measuring the deflection or compression under load, typically offering higher precision but often requiring more complex installation, such as replacing existing suspension components or integrating into the frame.
