EID Weighing Drafting Race Integration

EID weighing drafting race integration – Integrating hardware into a cattle race requires careful attention to spatial ordering and structural placement. Mounting EID antennas directly onto heavy galvanised steel frames can detune the EID reader signal and cause missed tag reads.

1. In-Race Component Ordering

To maintain continuous cattle motion, hardware should follow this sequence:

[Forcing Tub] ──► [Curved Sheeted Race] ──► [EID Panel Reader Station] ──► [Weigh Scale Platform] ──► [Auto Drafting Gate] ──► [Cattle Crush]

EID Antenna Placement: Positioned at the entry of the weighing zone so the tag is identified before the animal steps onto the load bars.
Weigh Platform Installation: Located immediately after the read zone, allowing the weight to stabilise while the animal moves forward.
Drafting Gate Integration: Positioned right after the weigh platform or at the exit of the cattle crush (such as the HD 1500 Series).

2. Preventing EID Metal Interference

Galvanized steel races interfere with the electromagnetic field generated by EID panel readers. To avoid read errors:

Non-Metallic Buffer Zones: Mount EID antenna panels on high-density polyethylene (HDPE) or timber spacers, maintaining a minimum 100mm offset from steel tubes.
Isolation Gaps: Ensure an isolation gap (using plastic or rubber washers) exists where the panel mounting frame meets the steel race wall.
Cable Routing: Route antenna co-axial cables away from parallel 240V/12V power lines to eliminate signal noise.

3. Loadbar and Weighing Platform Setup

Rigid Base Foundation: Loadbars must sit on a clean, flat concrete surface. Any movement under the loadbar frame will distort weight readings.
Debris Clearance: Keep a 20mm clearance gap around all four sides of the weigh platform frame to prevent dung, stone build-up, or mud from binding the scale.
