Load Cell Choice for dynamic checkweigher system

  1. Mar 22, 2016 #1
    Hello everyone, Greetings of the day.
    My name is Zeshan, I am automation engineer, I am stuck in problem of automation of weighing and sort system in chicken slaughter house using plc and load cell. Everything is done right but load cell is not giving me the right weight to make the right decisions. I have a "moving line of hanging chickens" running at 8000 chicks/hr, the platform where the load cell is connected that has a length of 11.5cm and the time for one chicken to pass over that plat form is 350ms. now the problem is that the conventional s.type load cell and digital indicator combination which i am using is not fast enough to determine the exact weight of chicken in this short time. the min capacity of load cell should be 30kg(plat form assembly + 2kg chicken)
    So please suggest me which type of load cell and indicator i should use to match the speed of the system.

    This problem has been solved by industry. A good search term is "check weigher". Wikipedia has a good entry here:
    https://en.wikipedia.org/wiki/Check_weigher
    It gives various suggestions for methods.

    I also think your weighing platform is much too heavy compared to what you are measuring and that combined mass is slowing the response of your measuring system.

    Thanks for your response, I have searched with "check weigher" term but all platforms throw me with different company made checkweigher assemblies like CAS and others but I can't find a specific load cell which I can use in my system..
