The WGJ-8-LCD automatic poultry weighing system during the breeding process
The automatic poultry weighing system is designed for continuous control of birds weight growth. The JOTAFAN WGJ-8 automatic poultry weighing system consists of scales pans in a poultry house that are connected to the controller or (optionally) to a PC computer.
Each of connected to the WGJ-8-LCD controller scales pans (WGJ-W or WGJ-I) controls independently and continuously the value and change of weight on the weighing platform and records a probable bird weight. Thanks to this solution the system can simultanously and continuously record weighing acts on all scales pans with few seconds intervals between bird's getting in and out of scales pan. Each bird is weighed seperately despite the fact that there are other birds on the platform as well as droppings and bedding.
The WGJ-8-LCD controller takes weighing acts from scales pans and records each of them in its memory together with date and time. In this way, it is possible to collect data from 1000 days of the breeding process for each of scales pans conected to the controller on the assumption of about 9000 weighing acts per day on each of them. There can be conected to the controller up to 16 scales pans that can be grouped in 'flocks' - up to 8 flocks (inventory buildings).
Additionally, it is possible to connect to each of the flock the sensor of microclimate parameters, e.g. JOTAFAN RHT-CO2-10k that measures temperature, humidity and carbon dioxide concentration. There can be measured up to 6 different microclimate parameters including - except above mentioned - ammonia concentration, hydrogen sulphide concentration and one defined by the user. Data from sensors are also recorded. It is possible to programme alarm thresholds, after exceeding them the WGJ-8-LCD controller reports an alarm (displaying a message or change of alarm output status).

The controller’s memory contains standard curves for basic flocks (broiler and parent flocks): ROSS-308, COBB-500, HUBBARD F-15 and FLEX, as well as for turkeys: BIG-6 and BIG-9.
This device is equipped with interfaces: USB and RS-485 that enable to connect a PC computer in order to control the scales system remotely, reading of collected data and analyse them in greater detail.
The WGJ-8 controller can be also equipped with an Ethernet module or WiFi giving possibility to its connection (by means of a wired or wireless router) to the Internet network or wireless data transmission between poultry houses and an office of a social room. Thanks to this solution it is possible to connect quickly and easily all controllers on the farm in the network and control them remotely. Our offer includes a few types of antennas for WiFi installation. We also offer configuration and commissioning services.
