  11. 11. The Problem with Traditional Load Cells<br />Software + Programming<br />$3,000-$5,000<br />Data Acquisition<br />$99-$3,000<br />Signal Conditioner<br />$149-$300<br />Resistive Load Cell<br />$350 - $ 1000+<br />Big<br />Complex<br />Analog<br />Expensive<br />Traditional solutions are bulky, complex and expensive <br />You need to have diverse engineering skills to utilize one!<br />
  12. 12. Loadstar’s Digital Solution<br />Capacitive Load Cell<br />$99 - $ 699<br />LoadVUE<br />software<br />$99 - $ 299<br />Low Profile<br />Easy to Use<br />Digital<br />Low Cost<br />Integrated<br />Loadstar makes it easy to use load cells<br />Anyone can use it. As easy to use as a digital camera!<br />
  13. 13. How it Works<br />A (Area between plates)<br />Capacitance is the ability of a system to store charge<br />It varies directly with area between the plates & dielectric constant<br />It varies inversely with the distance between the plates<br />The rate at which the current in the capacitor decays can be used to calculate capacitance<br />An oscillator circuit is used to convert the charge discharge cycle into frequency<br />The frequency is proportional to the capacitance which is proportional to applied load <br />Loadstar typically measures a change in d, but has patents for measuring changes in k or A.<br />(k)<br />d (Gap between plates) <br />Freq.<br />Current<br />
  14. 14. F<br />L<br />F<br />The advantage of Capacitive Sensing<br />Resistive Load Cell<br />Capacitance Load Cell<br />vs.<br />R  L<br />C  1/d<br />F<br />R<br />d<br />C<br />Resistivity change is of the order of 0.2% for full scale loading for strain gauge load cells<br />Capacitance change is of the order of 50-100% for full scale loading for Loadstar’s load cells<br />F<br />F<br />F<br />Key Reasons to use Capacitive Sensing Include:<br />- High sensitivity in small packages<br />- Digital signal less prone to noise issues<br />- Less expensive than comparable resistive sensors<br />- Fully integrated solution with high level digital outputs<br />
  15. 15. The Benefits of Digital<br />Resistive Load Cell<br />Capacitance Load Cell<br />The output of the circuit we use is TTL 0-5V frequency whose frequency changes by 30-100% based on gap change<br />They can be measured by a microcontroller without need for an ADC<br />Resistive load cells have to resolve micro-volt changes in the midst of noise that could be several orders of magnitude higher<br />They require careful power regulation & amplification prior to digitization by an ADC<br />A digital system is inherently less noisy and easier to incorporate into embedded circuits<br />
  16. 16. Sensor Networking Technology<br />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<br />Loadstar can network thousands of sensors together over the Internet<br />Browser-accessible software available to access data from anywhere<br />
