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. Six wire load cell connection . The two sense wires are capable of measuring the actual excitation voltage seen at the Wheatstone bridge inside the load cell, therefore the mV signal from the load cell can be adjusted according to the actual excitation it experiences. The 6-wire cable is best suited for longer runs where remote sense lines can be used Hi, I am trying to acquire data from a 3133_0 - Micro Load Cell (0-5kg) - CZL635 . 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. Testing the Scale. The main difference in function of these 2 types is that load cells with a 6 wire cable can compensate for variations in the actual excitation voltage they receive from the amplifier/indicator. LAUMAS is present in over ninety countries around the world through a dense network of dealers. I want to use only one load cell, but I saw on Internet that these load cell need another load cell to work. Verify Your Load Cell Wires. Table of content: Video Tutorial. When connecting 4 wire load cells together into a junction box before the weight indicator/transmitter, we recommend using a dedicated 6 wire load cell cable (for example the Thames Side polyurethane cable CA-PU-5.7MM-6C) to connect the junction box to the indicator/transmitter. 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. 6 Wire Load Cell Diagram. Most load cells have 4 wire connections (+/- Excitation, +/- signal) and terminate in a local summing box. Arduino Code to Read Weight Value from the HX711 Module. The extra sense pair are used for sensing excitation supply to load cell. 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. All these measures do not have to be considered with the 6-wire load cells. What types of load cell can be found in the marketplace? These four load cells are then connected to a junction or summing box before the indicator. // Step 1: Upload this sketch to your arduino board // You need two loads of well know weight.

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. If an installation engineer wants to shorten the cables, they can do so without compromising the load cell performance. 4 Wire Load Cell. Use the 4-wire cable for repairing or extending existing cable. VKK1-4 /VKK1R-4 Junction box. 4-WIRE / 6-WIRE LOAD CELLS A load cell may have a cable with four or six wires. These are sometimes called +Reference (or +Ref) and -Reference (or -Ref). Wiring the Load Cell to the HX711 Module and Arduino. 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. Wiring color code diagram for Transducer Techniques Load Cells available online for download or viewing, come checkout other online services. With long cables, there will be a drop in voltage from the original value supplied by the amplifier/indicator and the advantage of a 6 wire load cell is that this drop in voltage can be quickly and effectively compensated without it affecting the weight measurement. For the best experience on our site, be sure to turn on Javascript in your browser. If load cell and indicator distance is short then used this type of load cell. 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. Rice Lake 6-Wire Standard Load Cell Cable6-wire cable is most commonly used in commercial applications where multiple load cells are employed. A six-wire cable, besides having +/- excitation and +/- signal lines also has + and - sense lines. The full-bridge cells come typically in four-wire configuration.

Switch Box For Lights. Typical maximum excitation voltage is around 15 volts. 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. Otherwise there will be no sense input and therefore no reference point for the signal conditioner. www.groupfourtransducers.com. The output between them should be equal or to a value specified in the datasheet. The resistance of an electrical cable (conductor) varies according to its length and any temperature changes, resulting in variations in the excitation voltage at the load cells. When connecting 4 wire load cells together into a junction box before the weight indicator/transmitter, we recommend using a dedicated 6 wire load cell cable (for example the Thames Side polyurethane cable CA-PU-5.7MM-6C) to connect the junction box to the indicator/transmitter.
