Fault detection of load cells and corresponding replacement – we are blessed
1. Fault judgment
When the electronic scale presents the following phenomena, it is necessary to see whether the load cell presents a problem.
1) If the electronic scale does not show zero, the display screen continues to shine or show zero in the future, and the weighing number does not appear when weighing.
2) Electric ...

Wiring of weighing strain gauge tension and compression sensors – we are in control
Strain gauge tension and compression load cells are available in two different input and output wiring methods:
The first is the four-wire connection method.
The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.
