An interface cable is then run from the summing box to the instrument location with either 4 or 6 wires. We recommend that you do not shorten the cable of a 4 wire load cell if it is too long; it is better to coil up the cable. This will compensate for any voltage drops over the length of cable between them. 8 \$\begingroup\$ I have a 3-wire load sensor that looks like this: I'm trying to wire it up to my Arduino to detect changes in weight. 12 Gauge House Wire. With 6-wire load connection, it also compensates for lead resistance, allowing long cable runs. Rice Lake 6-Wire Standard Load Cell Cable6-wire cable is most commonly used in commercial applications where multiple load cells are employed. Connecting positive and negative voltage to the black and white wires (either way) will result in the red wire being, ideally, exactly half the voltage. There are no sense wires to compensate for the new cable length. 4-Wire Load Cell (1/5/10/20/200kg) with HX711 and Arduino. These four load cells are then connected to a junction or summing box before the indicator. To keep your login experience secure, we request you to verify your identity. Also from most specifications the Red wire is the "output". Use the 4-wire cable for repairing or extending existing cable. Think of these 3 wire load cells as potentiometers; the red wire is the wiper. In this example A = 10 kg. I bought a load sensor (SN-10245) with 3 wires (black, white, red) and I also bought the Load Cell Amp HX711 which need a 4 wires input. Join the world’s largest weighing community. The Sense (reference) wires are connected to the sense terminals of the weight indicator, so that this can measure and adjust the amplifier on the actual voltage that arrives to the load cells. So a 2.96 mV/V load cell will provide 29.6 millivolt signal at full load when excited with 10 volts. We have a strong presence on social media, follow us on your favourite channels to stay up-to-date on news and events of LAUMAS’ world. The 6-wire load cells are therefore preferred over those with 4 wires, also on these load cells there are no limitations in the event the installer wants to shorten the cables. What is the difference between 4 and 6-wire load cells? The resistance of an electrical cable varies depending on temperature and length, given that we can say that as the temperature and the distance changes there is a voltage drop that the 6-wire system allows to be compensated without affecting the measurement. Copyright © 2018 MVM Weighing Community PVT LTD. All rights reserved. The 4-wire load cells are thermally compensated and calibrated in relation to the length of the cable which is supplied as standard; to not compromise the calibration and compensation it is not recommended to shorten the cable of a 4-wire load cell; in the case of the weighing plant there is a weighing indicator or transmitter with a 6-wire input and a junction box-parallel, we recommend using a 6-wire cable to connect to the weighing indicator – transmitter to compensate the voltage drop on the stretch of cable between the junction box and the indicator itself. 4 Wire Load Cell. If the indicator has a 4-wire input, it is recommended to use a shielded cable with a significant cross-section (minimum 1 sq.mm) in order to contain the voltage drop between the junction box and the weight indicator. The summing box adds the signals from each load cell together … If you have a 6-wire signal conditioner with a 4-wire load cell it is important that you link the sense and excitation terminals at the signal conditioner. 4-Wire Interface Cable runs do not sense the excitation at the summing box location. The above precaution about cutting the cables does not apply to load cells with a 6 wire cable. The Sense (reference) wires are connected to the sense terminals of the weight indicator, so that this can measure and adjust the amplifier on the actual voltage that arrives to the load cells. So once you have established two data pairs, you can interpolate the rest. Depending on the model, the load cells may have a cable with 4 or 6 wires plus the screen. This sense … In any event, the cable should be well shielded and have sufficient cross section (at least 0.2 mm2) to limit the voltage drop along its length. The digital multimeter is connected between the positive signal wire and the negative signal wire of the load cell. 5 VOLTAGE REGULATORS LM78L05 LM79L05 (p/n LM78L05ACZFS-ND) (p/n LM320LZ-5.0-ND) POWER SWITCH Switch (DPDT) SW102-ND Double Pole Double Throw (DPDT) Alternatively, a DPST (Double … The 6-wire load cells are therefore preferred over those with 4 wires, also on these load cells there are no limitations in the event the installer wants to shorten the cables.
