Answers
1. Where can I find detailed data sheets on Silicon Designs accelerometers? Data sheets on all products can be found on the Product Specifications or Reference Materials pages of this website. Click on the product number to open a PDF featuring full details. 2. How can I place an order? Use our Request Quote page. Enter your contact information and the product or products you are interested in, and our dedicated sales team will respond within one business day. We will confirm the products will meet your needs and prepare a quote for you right away. 3. Can I order products directly from your website? We prefer to take orders after reviewing your project requirements with you. We like to take the extra time to learn about your needs before you place an order to ensure you get exactly what you need. By understanding your needs we may be able to recommend a product that could save you money or perform better for your intended use. 4. What are your terms? US TERMS: All prices are FOB Issaquah, WA. Terms are NET 30 or Visa/MasterCard. EXPORT TERMS: All prices are in US dollars and are FOB Issaquah, WA USA. Terms are prepaid or Visa/MasterCard. A $35 handling fee is added to each foreign shipment to cover completion of Customs forms. CUSTOM ORDERS: "Custom Order" pricing applies to accelerometers with special performance screening, non-standard g-ranges, custom cable lengths, or custom connectors. For Custom Orders you must either wait for these devices to be built along with our next scheduled build, order 10 or more devices to force an earlier build, or pay a $1000 lot charge to force an earlier build. 5. Do you manufacture everything in-house? Yes, Silicon Designs has a fully staffed manufacturing facility, including multiple clean rooms, in its Issaquah, WA building. SDI accelerometers are completely manufactured in-house by an expert production staff with many years of experience and a dedication to excellence. To learn more about our facility and people, visit our Company page. 6. What are the standard quality and return levels at SDI? Silicon Designs makes quality a top priority. No one wins when a customer receives a defective product, so SDI makes it a point to ensure that doesn’t happen. A highly skilled and well trained production team makes perfection the standard, and each unit is inspected and tested prior to shipment to assure clients receive an exceptional product. 7. Just in case something does happen, how do I return a product to SDI? Please visit our Returns page for information and instructions. 8. My accelerometer appears to be broken. When I place it on the desk with the lid facing up it reads +1G. How do I fix this? SDI accelerometers respond to the Earth’s gravity, and if you are on Earth, then you are in a +1g field. Turn the device over and you will see a -1g reading, which you can use to perform your own bias calibration of the device. 9. I have a 2430/2440 accelerometer module with an extra "yellow" wire. How do I connect this extra wire? The yellow wire is not used in the 2430/2440 and you can cut it off or leave it unconnected. 10. Unlike some other accelerometers, when I vary the supply voltage slightly or change the length of the wiring I do not need to re-calibrate. Why is this? For our 2210/2220/2240/2260/2430/2440 and 2460 accelerometer modules, the internal electronics utilize a power regulator and output buffer amplifiers. As long as you stay within the voltage specification, the devices do not vary in output. 11. Do I need a charge amplifier or signal conditioning to use my accelerometer? SDI accelerometers have integrated amplifiers, so you will never need an additional one. Signal conditioning is optional. 12. My tri-axial accelerometer is warm to the touch when I use it. Is this normal? Depending on the supply voltage, the 2430, 2440, and 2460 modules can become warm to the touch. This is normal and expected and should not be a cause for alarm. If you have another module and it becomes warm, you may have surpassed its voltage limit and it may be damaged. 13. Are the accelerometer modules water-proof? What is the IP designation? While all models are considered weather-proof, only the 2240 can be used while submerged. Please CONTACT US prior to use so we can walk you through the process. The IP designation of the rest of the modules is IP61. 14. Can you manufacture custom 3 volt versions of the 1210/1221/1010? We only build 5VDC versions at present. 15. I want to purchase 500,000 units from you for a cell phone application. Can you give me a great price? We build a very accurate device in a gold plated ceramic package. Each instrument is hand built and calibrated. This is not the type of accelerometer that you would use in a consumer product. It is more likely you would use our unit as a reference to calibrate a consumer product. 16. I am using a 2210 in single ended mode. I am using the green wire for signal output. What do I do with the unused "white" wire? Leave the white wire disconnected. Do not connect the white wire to ground as you will overheat the device and cause premature failure. 17. Do I really need calibration, and why is it included in the purchase price of the 2220, 2240 and 2440 but not the other modules? Some customers do not need this level of detail so we have made them optional on some models. Our higher end devices all include the data. 18. I see some of your devices are rated to 125C. Can you provide higher temperature versions? Our 1010 and 1221 accelerometers have been used up to 175C in some applications. If you have plans to use SDI accelerometers outside of their standard range, please check with us first. 19. We have a 2210 in our lab that is 7 years old. Can you provide a calibration sheet for it? We keep records going back 10 years however we would recommend that you return the device to us to be recalibrated as 7 year old data may no longer be accurate. 20. I need a better device than your normal specification. How would I go about ordering this? Contact us by phone or e-mail. There are many upgrades for all of our devices and pricing depends upon the degree of difficulty, the quantity, and timeframe required. We can upscreen existing units or build to your specification. 21. I need to attach a label to the wiring of my module, but it keeps sliding off. How do I attach a label? The cable has a low friction Teflon coating. The best way is to glue the label onto the device's case. 22. I would like a custom module with longer cables and a connector attached. Can you do this? Longer cables can be provided at additional cost. The most cost effective way to do this is to order at least 10 units. Because of the number of different plug types and wiring variations, we do not normally attach custom plugs except for high volume orders. 23. Is it possible to re-calibrate my module? Do you adjust the accelerometer when you do this? How often do you recommend we do this? We can recalibrate the module. We do not adjust the accelerometer; we just provide calibration data for its current state. 24. Can you repair all of the modules that you manufacture? We can only repair models 2420, 2422 and 2460 at this time. 25. Why can't I return custom parts? Custom parts were built to your specification and therefore have limited marketability to other users. 26. Is it possible to use a USB connection with the G-LOGGER? USB/ serial converters do not work reliably with the G-LOGGERTM. We have tried at least 5 different types. If you have a laptop we suggest you use a type II or type III PC card to serial adapter. We have no plans to update the G-LOGGERTM to USB at this time. 27. Is it possible to provide more memory with the G-LOGGERTM? Unfortunately more memory is not available. 28. Where can I download manuals and software for the G-LOGGERTM? G-LOGGERTM manuals are available to download on the Reference Materials page. |
