Master-Slave system for weighing large and long cargo

In the process of weighing and moving long (structures more than 12 m long) and non-standard large-sized cargo (containers) on scales, there is a problem of safety and reliability of measurement results. The use of a Master-Slave weighing system consisting of several scales allows us to solve this problem.

Operating principle of the Master-Slave system:

• some scales are the main ones («Master»), all the rest are subordinates («Slave»). In total, the system can use up to 4 scales;
  
• «Master» scales add to its measured weight value the weight values of all «Slave» scales included in the system and display the total weight of the load being weighed;
  
• «Slave» scales display «_ _х_ _», where x is the number of the scales (possibly from 1 to 3). Data transmission from the scales is carried out via radio channel.
  
• both the total mass of the load can be displayed directly on the main «Master» scales, or the measured weight value from each «Slave» scale can be recorded. Then the resulting weighing data can be transmitted to any EHP transceiver device via a radio channel, for example, Teledata USB.
  

Features:

• mechanical strength margin for metal structures - 500% of Max for static load; the maximum permissible load of the measuring set is 150% of Max;
• all series of EHP crane scales can be used as a Master-slave system;
• The Master-Slave function can also be retrofitted to the customer’s existing EHP scales, or if the customer already has a Master-Slave system, add new EHP crane scales to the system (the maximum number of scales in the system is 4);
• «Master» scales can transmit data to a computer, portable display panel, backup display and other peripheral devices;
• all scales included in the Master-slave system can be reconfigured at any time without changing the configuration for use under normal conditions as scales operated independently of each other.
