load cell strain gauge

It depends on your bridge configuration and power budget. 350 Ω is a solid starting point for most weighbridge and tank cell designs. Higher resistances like 1000 Ω draw less current and generate less heat, which suits battery-powered instruments. Lower resistances around 120 Ω are still used in some high-output applications. Kingmach can supply the same pattern in different resistances if you want to evaluate both.

Yes. We regularly adjust grid length, number of grids, and backing shape to match customer elastic elements. You can send us a drawing of your flexure and we will suggest a gauge layout, or we can work from your CAD file to produce a prototype set. Modifications often include adding solder pads, sealing tabs, or alignment marks.

We can recommend specific cyanoacrylates, two-part epoxies, or phenolic cements based on your curing facilities and operating temperature range. For instance, a fast-cure cyanoacrylate works well at room temperature for many low-creep applications, while an epoxy might be needed for high-temperature transducers. We also supply strain gauge adhesives if you prefer a single source.

Our self-temperature-compensated grades are matched to common elastic element materials such as aluminum, steel, and quartz. Let us know the material and working temperature range, and we will select the appropriate STC number. For mixed-material structures, we can also discuss gauge layout options to minimize thermal zero shift.

Each batch goes through resistance tolerance checks, gauge factor sampling, and grid alignment inspection. We keep records of raw foil lots and processing parameters. If your calibration process relies on a tight gauge factor range, we can sort and supply gauges within a narrower tolerance band.
