1. Overview
    MSFP-F hook load protection device is a kind of electronic indicating instrument with stable structure, which is used to monitor the pressure changes of weight indicator system. It transmits current signal proportional to hydraulic pressure to host computer, and then host computer transmits the digital signals to processor with analog-digital conversion circuit. With data processing technology, the device calculates hook lifting load, and compares actual load with preset alarm limit value, so as to realize the overload protection of hook load.


2.  Main Functions
    . Display the operation state of system, including normal operation, over-limit alarm or brake;
    . Digital display hook load; digital display the value of pressure sensor;
    . Set the alarm limit value of hook load and brake limit value. When the load exceeds the limit value, it will alarm or brake;
    . Set weight indicator index, that is the correspondence between pressure value of sensor and load;
    . By means of 5 standard pressure points, it calibrates pressure sensor;
    . Test brake function: to ensure the system can carry out accurately and effectively the protection measures when emergency happens.
