SFJ-B Point-to-depth and Point-to-weight Meter

SFJ-B Point-to-depth and Point-to-weight Meter

Jingzhou Mind Science and Technology Co.,Ltd.































1. Overview
    By measuring the descent speed and depth of fishing wheel drop, and the object parameters such as dynamic load when it falls and rises, and synchronous displaying via LCD, SFJ-B point-to-depth and point-to-weight meter makes the operators real-time know the current working condition. As the requirements of safe operation of equipment, the device can set the normal working range of running speed, running height and object dynamic load. When running parameters excess the normal working range, the device gives a sound-light alarm to prevent operational accidents.


2. Main Functions
    . Display the depth when object descends and ascends;
    . Display the speed when object descends and ascends;
    . Display promotion load value of object;
    . Display wellhead position;
    . Alarm when descent depth reaches set depth;
    . Alarm when decent and ascent speed exceed set speed;
    . Alarm when ascent position reaches set position in wellhead;
    . Alarm when load value exceeds set load value, and remind the operation, and then protect the safe operation of object.
