Precautions for the combination of multiple load cells

Among the sensors, the mechanical sensor is one of the most common sensors. Perhaps the one that you see seldom is the use of a single load cell, and the most common is a combination of multiple load cells.

  In an electronic weighing instrument composed of multiple sensors, in addition to selecting the load of the load cell and installing it correctly, attention should also be paid to:

  1. Fixed pillars and jack supports should be installed on both sides of each load cell. The height of the fixed pillar should be slightly lower than the height of the sensor by 3mm to 4mm, so that when you need to replace or maintain the sensor, use a jack to jack up the scale body, and then insert a pad of appropriate thickness on the fixed pillar to separate the sensor from the bracket by 4mm Up to 5mm, as a temporary support, on the other hand, when the scale body is overloaded, it can protect the sensor.

  2. In order to prevent the scale body from moving in the horizontal direction due to impacts and other reasons, appropriate stoppers should be installed according to the structure of the scale body. When the stopper is installed, no force should be applied in the vertical direction, but it can offset various horizontal forces acting on the scale body.

  3. The load cell must be installed on a horizontal surface, and must be kept level when there is a load to prevent the load cell from being damaged due to uneven load distribution due to tilt.

  The combination of multiple load cells^ important installation problems are^ need to pay attention to, because the load cell installation directly affects the accuracy and service life of the load cell, inaccurate installation will not only lead to measurement errors, but also cause long-term incorrect use The method must lead to a qualitative change in the use of sensors.
