Load Cell Sensor - 100g Parallel Beam

If you’ve ever stood on a scale and wandered how the device measures weight, and furthermore how it accurately measures the same weight consistently no matter how many times you weigh yourself, then be sure to read on about this fantastic little 100g Load Cell Sensor, which is capable of measuring strain by carefully monitoring the internal resistance of bonded wires as they bend with the metal, which can then be identified as Newton force or weight depending on the application.

The design of these Parallel Beam Load Cell Sensors make them ideal for mounting below small platforms in a similar fashion to common kitchen/baking scales, and should be mounted to a solid structure via the M5 mounting holes, with the measuring surface mounted to the M4 mounting holes. Then, when you place an object on the measuring surface, it ever-so-slightly bends the parallel beam, creating a sheer force that extends the measuring wires, which affects the internal resistance so as to present you with an estimated force measured in grams or micro-grams depending on your system.

This load cell is designed to be used with our HX711 Load Cell Sensor Interface Module, and is often purchased alongside our IOT Devices for automated stocking systems.

Please Note: These 4-Wire Load Cells have been pre-calibrated during the manufacturing process. As such, it’s imperative that you never cut, shorten or otherwise modify the cables that are included, as this will affect the resistance of the sensor, resulting in inaccurate weight measurements.

Typical Applications for these 100g Parallel Beam Load Cell Sensors:

While many of the Load Cell Sensors that you can buy on the market are focused towards capacities of 1kg and higher, with some even extending up to 150kg while still falling within the hobbyist range, these little load cells cater to the opposite spectrum, and are capable of measuring very small weights as low as 0.1g. This makes them ideal for measuring very small parts like nuts, bolts, screws and even resistors, as well as for small quantities of refined products like baking ingredients, chemistry components or gardening powders.

Just remember though, that you do need to use load cells like these in conjunction with a load cell amplifier such as the HX711 Load Cell Interface Module that we stock. With these parts in hand, however, setup and installation is as easy as connecting the wires to the HX711 according to the table above, mounting the load cell onto a solid surface, and then mounting a weighing platform onto the other end. After that, you can route the measurements via a microcontroller, to a personal computer, or directly to an LCD display depending on your project, giving you exact weights between 0.1g and 100g for whatever you need to weigh.
