This can have an important effect on performance and further endorses the need to ensure load cells are of the highest quality. A load cell is used to determine mass: The weight force exerted by the sample is converted into an electrical signal by the load cell. Qwiic Scale Hookup Guide April 11, 2019. A Load cell used to measure tension will not reflect negative reading if installed upside down and will result in an erroneous reading. Because 6 wire load cells have a +sense and – sense wire to measure the actual excitation voltage over different wire lengths the wires can be cut if necessary without compensating the functionality of the load cell. Download or Print the Load Cell Brochure . Zemic Europe B.V. T: +31 76 50 39480 Nr. The force measured by the object load cell with its amplifier and recording system will be called “indicated force”. However, if the load cell is installed correctly and the readings are still negative, verify the wire connection according to the color code specified by the manufacturer. It should be remembered that in many applications, the actual live working range of the load cell (and hence the available electrical output) will be reduced depending on the dead weight of the vessel and any overload requirements. ** For load cells with a 6-core cable (including sense wires): +ve sense is and -ve sense is (except for T34D and T38) -T66 is available with 6 wires as standard, but a 4-wire version is available as an option.-For High Temperature versions of the standard load cells listed above, as well as customised versions of our standard load cells, please refer to the individual product data sheet. The ease of measurement with a compression load cell helps to speed up processing and output, reducing the time spent obtaining results and ultimately lowering costs. Once the load cell has the full bag weight on it, the conveyor will start dropping the salt into the funnel and down to the waiting bag. Compression load cells also offer long-term stability, and this stability and accuracy can be further ensured with regular load cell calibration services offered by companies such as HBM. • Quality load cells that eliminate drift and recalibration • Wide operating range • Easy to apply Horizontal measurement PFTL 301E The horizontal Mini series PillowBlock load cells for the web processing industries have the same dimensions as conventional load cells and mount in the same way.
