Install suspension systems with adjustable linkages to maintain the ability to evenly distribute loads among load cells. Gas Turbine Engine/Rocket: High accuracy measurements of the volumetric flow of gas through the pipeline. As stated before, the load cell should always be the intermediate point between a fixed surface and the introduced load path. A pressure gauge is attached with the load cell to measure the pressure inside the cell. When mounting the load cell, it is placed between the force introducing structure and the base, which ideally are two parallel surfaces. The Mounting Set CMX-3510 is a complete mounting arrangement for the Load Cell 3510 and the Load Cell 3410. Make sure to put some form of rigid spacers between the mounting plates and the load cell. Load cell mounts that do not allow for mechanical expansion can cause permanent damage to the load cell or frame. or load cells up to 5000 kg. Button Load Cells. Also build a frame that avoids the intrusion of ice, moisture and other weather-related factors that can cause corrosion or mechanical deformation. To avoid this, place the load cell, connection cabling, and electronics in a shielded housing. The load direction should always comply with the load cell manufacturer’s installation manual. Load cell mounting design Each load cell installation is unique; consult a structural engineer when in need of very high accuracy, long-term stability, custom applications and specifications, and when using varied R&D environments. Place load cells at all corners of the supporting structure to maintain the full weight or load. Before Installing • Determining Microvolts per Graduation • Load Cell Mounting Hardware Safety Guidelines • Load Cell Trimming • Load Cell Troubleshooting • Selecting Replacement Load Cells • Load Cell Wiring Guide • Calibrating Vessel Weighing Systems While selecting the appropriate load cell model for an application is important, its measurement output could be meaningless if the load cell is not properly mounted and installed. Load cell compensates for temperature differences to provide accurate output. The turbine rotor turns the rotor blades by gas flow into the meter, measuring gas velocity. A force shunt is any device or path through which a portion of the force flow or load is diverted. For best results, always follow the manufacturer’s installation instructions and ensure that installers are properly trained. A failure to maintain axial loading could result in bending moments. Here at Flintec we offer a range of load cell mounts for use in different applications. As one of the smaller load cell designs, button load cells received their name from their raised center-button. They are used in different applications including bench & floor scales, machines, the weighing of vessels and silos and truck scales. This can happen in two ways: when the frame and mounts improperly guide the load, and when any attached structures (such as supports, safety cables, pipes and hoses) create “force shunts.”.
