Overload detection for dam gates

Customer requirement

The designer of the operating system for a hydroelectric dam wanted to implement a control that would ensure the safe opening and closing of the gates.


Scaime Solution

Customized load pins are fitted to the gates operating systems. These sensors measure the force transmitted by the motors to open or close the gates. To ensure highest safety level, the load pins are equipped with two strain gage bridges for measurement redundancy. The wheatstone bridges are connected to CPJ electronics providing 4/20mA output signals to the PLC and indicators for reading the force.


In the event that one of the gates is blocked, the loadpins will inform the PLC in real time, which will be able to stop the movement as quick as possible to avoid damage to the installation.


  • Special load pins with measurement redundancy
  • CPJ electronics for 4/20mA signals
  • Indicator PAX-D
