Load cells can be wired in two different input and output ways:
One 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 the time and time of use are very convenient, but when the cable is long, it is very simple to be affected by factors such as the working temperature;
The other is the six-wire connection method
The load cell rules of the six-wire system connection method and the secondary instrument panel assigned to the use have a reverberation input socket, and the use standard has certain limitations, but it is not easy to be determined by the working temperature and other factors, and has certain benefits in high-precision and accurate measurement and long-distance accurate measurement.
How to wire in two ways:
It is the first to clarify the switching power supply positive, switching power supply negative, positive response, negative response, positive data signal and negative data signal of the sensor socket on the display screen. If it is a 6-wire transmitter, the two groups of wires with very small sensor resistors are the switching power supply and the positive response; After receiving the display screen, the sensor is loaded, and the current value (millivolts) of the other two wires is accurately measured, and the display data signal is positive, and the display data signal is negative; If it is a four-wire value, the switching power supply of the display screen must be positively wired with the repercussions, the negative and negative repercussions of the switching power supply, and the four wires of the sensor should be measured with a multimeter, and the two with larger resistance values between them are the switching power supplies, and the other two are data signals;
According to the origin of the sensor, we can distinguish by the color of the wire, we are generally red for the switching power supply positive, black for the switching power supply negative, yellow for the data signal positive, white for the data signal negative.

The role and classification of safety barriers
In electrical intrinsic safety explosion-proof, we generally divide the workplace into explosion-proof areas and non-explosion-proof areas. There is the transmission of electrical energy between the explosion-proof area and the non-explosion-proof area, for example, the switches, buttons, sensors, etc. in the explosion-proof area are connected to the PLC placed in the electrical cabinet in the non-explosion-proof area through wires.
