ATO Pancake Load Cell 2000 kg
The ATO Tension and Compression Load Cell Pancake model delivers a flat, low-profile design with a capacity of 2000 kg. It features a sensitivity of 2.0±0.1mV/V and an overall accuracy of 0.05% F.S., including linearity, hysteresis, and repeatability. The design emphasizes symmetry and anti-eccentric performance, with an IP67 sealing rating to withstand harsh environments. This pancake format is well-suited for platform scales and truck-scale integrations where space is limited and even loading is critical.
Right Weigh 510 Series Onboard Scale
This interior onboard scale displays tandem axle group weights with a 2-inch gauge for clear readability. It emphasizes a simple installation and calibration process, designed to fit standard 2-1/16″ dash cutouts. The system is suitable for fleet applications seeking straightforward monitoring of axle weights on tandem-axle air suspensions, providing quick insights without extensive hardware changes.
Right Weigh 510-46-RK Tandem Axle Kit
The 510-46-RK kit provides on-the-ground axle group weight display with simple installation and calibration. An air line installation kit is included, enabling efficient integration with air suspension systems. Its design focuses on reliable readings and quick setup for fleets requiring accurate axle weight data in a compact footprint.
Right Weigh 202-DDG-02 Bluetooth Load Scale
This Bluetooth-enabled interior digital load scale supports air-suspension tractors, straight trucks, and tractor-trailer sets. It includes two air pressure sensors to monitor height control valves and displays the axle group weight in pounds or kilograms on a touchscreen LCD. It also offers programmable PIN access and the potential to estimate steer weight when installed on drive axles, providing integrated weight data for fleet management.
ATO 20 Ton Compression Load Cell
The ATO 20 ton compression load cell is designed for higher-capacity platform, truck, and rail scales. It offers a precision of ±0.03% F.S with strong linearity and repeatability, ensuring stable measurements under high loads. The robust construction uses alloy or stainless steel and is fully sealed with IP67 protection, making it suitable for demanding industrial environments and resisting eccentric loading.
Buying Guide: Key Purchase Considerations For Truck Scale Load Cells
Choosing the right load cell for truck scales involves balancing capacity, accuracy, mounting, and environmental resilience. The following factors help buyers compare options:
- Capacity and overload protection: Select a load cell with a capacity that matches your maximum expected load, plus a margin for safe operation. Consider models with overload protection and high shock tolerance for dynamic weighing on scales.
- Accuracy and stability: Look for low F.S. error, high linearity, and repeatability. Pancake (low-profile) designs provide even loading characteristics for platform scales, while traditional shear beam approaches may suit longer spans.
- Environmental sealing: IP67 or IP68 ratings reduce risk from dust, water, and cleaning solutions. For outdoor installations or wash-down facilities, sealed designs extend service life.
- Output and compatibility: Most truck-scale systems use mV/V outputs or digital interfaces. Ensure the signal type matches your instrumentation, and verify compatibility with existing indicators, controllers, and networked systems.
- Mounting and installation: Consider the mounting arrangement (top-plate, base, or bench-mounted), required hardware, and whether the installation is compatible with your scale structure and platform geometry.
- Installation complexity: Some options offer straightforward calibration and plug-and-play integration, while others may require professional alignment and commissioning.
- Maintenance and service life: Sealed constructions, corrosion-resistant materials, and manufacturer support influence long-term upkeep and uptime.
- Certifications and compatibility: For industrial and transportation applications, confirm compatibility with standards relevant to your region and industry, including any required certifications for high-capacity scales.
- Cost of ownership: Consider not only upfront price but also installation labor, calibration frequency, and potential downtime due to maintenance.
In summary, selecting the right truck scale load cell depends on matching capacity with application, ensuring rugged construction for outdoor and industrial environments, and aligning with your scale’s existing hardware and communication requirements. The five products highlighted here cover a range of capacities and configurations—from pancake low-profile cells suitable for platform scales to high-capacity compression cells ideal for heavy-duty truck and rail applications. A careful evaluation of mounting, wiring, and calibration needs will help ensure accurate, durable weighing in daily operations.
