Identity

The Weighing Scale (Platform) is an in-house biomonitoring apparatus featuring a suspended platform and hermetically sealed load cell, utilized to dynamically track real-time flock weight and statistical uniformity.

Overview

The Weighing Scale (Platform) is high-priority automation equipment for dynamic bird weighing. It provides continuous flock weight data to the Smart Controller. A common operational failure involves structural bridging—where accumulated droppings or feathers build up underneath the scale, transferring load to the floor and resulting in consistently under-recorded bird weights.

Structured Facts

Classification

Weight and Biomass Telemetry Equipment / Automated.

Purpose

Records continuous, real-time measurements of flock body weight and uniformity, forecasting market weights without the stress of manual handling.

Working Principle

Features a flat suspended plate connected to an IP68 hermetically sealed load cell. Bird weight deforms the load cell, altering the resistance of an integrated Wheatstone bridge to produce a proportional millivolt signal. A high-speed transmitter digitizes the signal, using statistical filtering algorithms to eliminate spikes from active movements or multiple birds stepping on simultaneously, recording only valid single-bird weights.

Technical Specifications

• Load Cell Protection: IP68 Polyurethane-Encapsulated (Rating Standards).
• Telemetry Sampling Rate: 10 to 50 Hz dynamic sampling (Transmitter Specs).

Capacity

• Scale Weight Range: 10 to 10,000 g (Standard Manuals).
• Daily Structural Samples: 1,000 to 3,000 weight measurements (Calibration Data).

Installation Requirements

Scale must be raised continuously using a winching system as the flock grows and litter height increases. Cabling must be run through protective conduit or armored sleeves to prevent bird pecking.

Operating Parameters

• Power Consumption Supply: 12 to 24 VDC (Controller Supply).

Maintenance

Scale must be checked and calibrated between flocks using certified weights. Requires regular cleaning underneath to prevent manure/litter buildup.

Cleaning & Disinfection

Must clear accumulated manure and feathers from underneath the platform to prevent structural bridging.

Advantages

Provides thousands of data points daily. Evaluates FCR and flock uniformity in real-time. Eliminates handling stress associated with manual catching.

Limitations

Accumulated manure, feathers, and litter can bridge the gap to the floor, absorbing the load and causing the scale to under-record weights. Acidic ammonia and moisture corrode exposed wiring connections. Exposed cabling is vulnerable to bird pecking, introducing electrical noise.
