Master-Slave system for weighing large and long cargo
Master-Slave system for weighing large and long cargo

Inthe process ofweighing and moving long (structures more than 12 mlong) and non-standard large-sized cargo (containers) onscales, there isaproblem ofsafety and reliability ofmeasurement results. The use ofaMaster-Slave weighing system consisting ofseveral scales allows ustosolve this problem.

Operating principle ofthe Master-Slave system:

  • some scales are the main ones (Master), all the rest are subordinates (Slave). Intotal, the system can use upto4 scales;
  • Master scales add toits measured weight value the weight values ofall Slave scales included inthe system and display the total weight ofthe load being weighed;
  • Slave scales display _ __ _, where xisthe number ofthe scales (possibly from 1 to3). Data transmission from the scales iscarried out via radio channel.
  • both the total mass ofthe load can bedisplayed directly onthe main Master scales, orthe measured weight value from each Slave scale can berecorded. Then the resulting weighing data can betransmitted toany EHP transceiver device via aradio channel, for example, Teledata USB.


  • 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 customers 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.
