Wiring of weighing instruments
Thread Content
I would like to ask how to connect 4 terminals of the weighing instrument when there are 6 output terminals? Short-circuit? handshake
Oh, it shouldn’t be just one of these; refer to the other wiring that’s in use
The relationship between the four-wire and six-wire configurations of load cells is illustrated in the figure below. The six-wire configuration connects +E and –E to the sensor using two wires. If all the instruments and sensors have six wires, connect them one by one ； If it’s a 6-wire gauge and a 4-wire sensor, cross-connect the two wires of the gauge to one of the sensor’s terminals. Placing the jumper at the instrument end can improve measurement accuracy ； If it’s a 4-wire instrument and a 6-wire sensor, use the two wires of the sensor as if they were one wire. The difference between the 4-wire and 6-wire configurations of load cells lies in the way the power is supplied to the measurement bridge: in the 4-wire system, the instrument measures the voltage of the bridge circuit, including the voltage drop along the power supply lines as well ； In a 6-wire system, after the instrument supplies power to the bridge circuit, an additional pair of wires is used to measure the supply voltage at the sensor side of the bridge circuit; adjustments or compensations are then made based on these measurements in order to eliminate the impact of the wires on the power supply. (The diagram above is only a schematic of the wiring and does not illustrate this principle.)
The junction box has 6 wires, and the instrument has 4 wires; is it okay if I connect only 4 wires? I won’t connect the extra 2 wires from the junction box
The picture isn’t very good, but I hope it’s helpful to you.
