strain gauge weight sensor

It is a load-measuring device that uses electrical resistance strain gauges bonded to a metal spring element. When weight is applied, the element deforms slightly, changing the resistance of the gauges. A Wheatstone bridge circuit converts this change into a voltage proportional to the load. Most sensors are temperature-compensated and calibrated to output a standard signal, like 2 mV/V.

Yes, we customize sensors regularly. Modifications can include altered bolt patterns, integrated mounting plates, special cable exits, or unique capacity ranges. We ask for a drawing or application details, then propose a design. Lead time depends on the complexity, but standard customizations often ship within 3–4 weeks.

Temperature changes can shift zero and sensitivity, but compensated gauges minimize this. Moisture and corrosion are bigger risks; we use stainless steel and welded seals for harsh conditions, achieving IP67 or IP68 ratings. For outdoor silos or marine environments, we recommend additional protective coatings or bellows seals.

We provide wiring guidance, calibration services, and troubleshooting remotely. For larger projects, we can arrange on-site commissioning or training. Since we design and manufacture in-house, our engineers have access to full test data and can help diagnose issues quickly.

It depends on the mechanical arrangement. Shear beam sensors suit platform scales and low-profile installations because they resist side loads. Compression sensors are better for vertical loads on a single point, like tank feet or hopper legs. We can recommend based on your structural constraints, and we supply both types.
