Precision Installation Techniques for Pig Weighing Equipment in Pig Farms

Foundation Preparation and Leveling

The foundation forms the cornerstone of accurate weighing system performance. Begin by selecting a concrete floor with uniform thickness exceeding 15cm, ensuring it can withstand dynamic loads from pig movement. Use a high-precision spirit level to verify floor flatness, identifying any deviations exceeding 2mm per linear meter. For existing uneven surfaces, apply self-leveling compound to create a perfectly horizontal base.

When installing on soil ground, excavate to a depth of 50cm and fill with compacted gravel layers. Each 15cm layer should be thoroughly compacted using a plate vibrator, achieving 95% Proctor density. Install a reinforced concrete slab (minimum thickness 10cm) on top of the gravel base, incorporating steel mesh reinforcement to prevent cracking under heavy loads.

Sensor Installation and Alignment

Proper sensor positioning directly impacts weighing accuracy. For four-sensor systems, mark installation points forming a perfect rectangle aligned with the weighing platform edges. The diagonal distance between opposite sensors should match within ±1mm tolerance. Use laser alignment tools to ensure precise positioning.

Each sensor must be installed perfectly vertical. Check alignment using a plumb line or digital inclinometer, maintaining deviation under 0.5 degrees from vertical. Tighten mounting bolts gradually in a star pattern to distribute pressure evenly, achieving final torque specifications per manufacturer guidelines. After installation, verify sensor height consistency using feeler gauges between sensors and mounting surface.

Platform Assembly and Connection

Assemble the weighing platform components according to manufacturer instructions. For modular designs, connect sections using precision-machined coupling pins with minimal clearance. Ensure all connection points align perfectly before tightening fasteners. Use thread-locking compound on critical bolts to prevent loosening from vibrations.

Electrical connections require meticulous attention. Route sensor cables through protective conduit to prevent rodent damage. Connect cables following color-coded wiring diagrams, ensuring proper polarity. Use waterproof connectors in humid environments and secure all connections with cable ties. After initial power-on, perform continuity tests to verify all circuits function correctly.

Calibration and Functional Testing

Initial calibration establishes baseline accuracy. Place certified test weights totaling 50% of the scale’s capacity at the center of the platform. Record displayed weight and compare with actual test weight Adjust calibration settings through the indicator’s menu system until readings match within ±0.1% tolerance.

Perform four-corner loading tests by placing 30% of capacity weights sequentially at each corner of the platform. Document weight readings at each position. Use the indicator’s corner correction function to balance readings, ensuring consistent measurements regardless of pig positioning. Repeat tests until all corners display weights within ±0.2% of each other.

Environmental Adaptation Measures

Temperature fluctuations affect weighing accuracy. In cold climates, install heating elements beneath the weighing platform to maintain sensor operating temperatures above 10°C. For hot regions, incorporate ventilation slots in enclosing structures to prevent heat buildup. Use temperature-compensated sensors to automatically adjust readings based on ambient conditions.

Vibration isolation proves critical in busy farm environments. Mount the weighing system on anti-vibration pads rated for the expected load capacity. These pads should dampen vibrations from nearby machinery while maintaining platform stability. For additional isolation, install the entire system on a separate concrete foundation isolated from building structures.
