11. The Problem with Traditional Load Cells Software + Programming $3,000-$5,000 Data Acquisition $99-$3,000 Signal Conditioner $149-$300 Resistive Load Cell $350 - $ 1000+ Big Complex Analog Expensive Traditional solutions are bulky, complex and expensive You need to have diverse engineering skills to utilize one!

12. Loadstar’s Digital Solution Capacitive Load Cell $99 - $ 699 LoadVUE software $99 - $ 299 Low Profile Easy to Use Digital Low Cost Integrated Loadstar makes it easy to use load cells Anyone can use it. As easy to use as a digital camera!

13. How it Works A (Area between plates) Capacitance is the ability of a system to store charge It varies directly with area between the plates & dielectric constant It varies inversely with the distance between the plates The rate at which the current in the capacitor decays can be used to calculate capacitance An oscillator circuit is used to convert the charge discharge cycle into frequency The frequency is proportional to the capacitance which is proportional to applied load Loadstar typically measures a change in d, but has patents for measuring changes in k or A. (k) d (Gap between plates) Freq. Current

14. F L F The advantage of Capacitive Sensing Resistive Load Cell Capacitance Load Cell vs. R  L C  1/d F R d C Resistivity change is of the order of 0.2% for full scale loading for strain gauge load cells Capacitance change is of the order of 50-100% for full scale loading for Loadstar’s load cells F F F Key Reasons to use Capacitive Sensing Include: - High sensitivity in small packages - Digital signal less prone to noise issues - Less expensive than comparable resistive sensors - Fully integrated solution with high level digital outputs

15. The Benefits of Digital Resistive Load Cell Capacitance Load Cell The output of the circuit we use is TTL 0-5V frequency whose frequency changes by 30-100% based on gap change They can be measured by a microcontroller without need for an ADC Resistive load cells have to resolve micro-volt changes in the midst of noise that could be several orders of magnitude higher They require careful power regulation & amplification prior to digitization by an ADC A digital system is inherently less noisy and easier to incorporate into embedded circuits

16. Sensor Networking Technology One of Loadstar’s key areas of expertise lies in networking load cell output to USB and WiFi enabled devices such as computers and mobile devices like the iPhone Loadstar can network thousands of sensors together over the Internet Browser-accessible software available to access data from anywhere
