The wiring method of the load cell is divided into four wire system and six wire system, and the specific wiring method is as follows:
Four-wire wiring method: the load cell is actually a resistance strain gauge, which is attached to the aluminum elastomer, through the stress-resistance principle, that is, when the gravity of the weighing object acts on the elastomer, the resistance value of the strain gauge on the elastomer changes, and becomes an electrical signal output through the Wheatstone bridge. The four-wire wiring method is divided into the forward wiring method and the reverse wiring method. The so-called positive wiring method means that the current flowing into the binding posts 1 and 3 of the load cell is positive, and vice versa.
Six-wire wiring method: The difference between the six-wire sensor and the four-wire system is that there is an additional shielded wire, that is, the shielded No. 1 terminal to the shell, which can eliminate the interference signal from the outside world and bring unnecessary errors. In practical applications, it can be selected and used according to actual needs.
In addition, care should be taken when using it:
1.Make sure the cable is not damaged, and if it is damaged, wrap it with insulating tape.
2.In order to ensure the sensitivity of the sensor during the weighing process, do not entangle the cable when wiring.
3.Make sure that the connector of the sensor is not loose, and if you find it, you need to tighten it in time.
