Load Cell Calibration

Analog load cells traditionally use either strain gauge or piezo designs, both of which give accurate readings but have some limitations. Capacitive technology now allows analog load cells to give precisely calibrated data from within a firm shell.

Capacitive technology works by measuring the change in capacitance when an object is placed on the analog load cell. This method gives readings quickly and can also support heavy weight loads. Miniature units require an external conditioner while normal and large sizes have this technology built in.

Analog Load Cells Work With Digital Devices

Analog load cells can be used equally well with digital and traditional indicators and calibration tools. USB outputs allow these devices to work across a wireless network for increased flexibility and applications. Since capacitive technology is sturdier than piezo and strain gauge designs, miniature models can support up to 200 pounds while large models can go as high as 10,000 pounds.

Capacitive analog load cells can be mounted on a variety of different surfaces and are resistant to changes in the environment. Units work well across a range of temperatures, although extreme hot or cold applications may require custom design.

Loadstar Sensors, Inc. makes both digital and analog load cells that incorporate capacitive technology. Our devices are offered in a variety of sizes, weight limits and custom shapes for final product or research and design applications.
