Q: What preparation work should do when testing our fiber optic module?
A: 1) During tests and using, it is better to add one metal base or heat dissipation
Power supply: it is better to use laboratory power supply (which can display the current) during tests, then can judge the module’s status easily, when integrating the module into the system, DCDC power module can be selected, and the DCDC module select the one that has filter, if the dcdc module doesn’t have the filter, then please add one filter.
When use laptop or PC to collect the data from our fiber optic module, please select the right data collecting card, the data collecting card should has photoelectric isolation ability. For more details, please contact with our sales.
Q: What input voltage should be provided for our fiber optic gyro?
A: ±5VDC±5%, and the current should ≥1A, so the impulse current can reach 1.5A at the moment of fiber optic gyro startup, this is very important, if the current is low, the fiber optic gyro may failed to start to work, if not work normally, the output data from FOG will be abnormal. And 15W power module (at least 10W) is recommended, for more details, please contact with us, we also can recommend the power module we used.
Q: What data type of the SkyMEMS fiber optic gyro?
A: it is integer data, this raw data divide by scale factor, the result is the angular rate (degree/s). the scale factor will be provided in the test report, every fiber optic gyro’s scale factor is different.
Q: Whether the fiber optic gyro lose data when outputting data at higher frequency?
A: please let us know what frequency you will use in your application, according to the frequency, and select the right baud rate, the fiber optic gyro will not lose data, and we also can provide solution based on your actual applications.
Q: How to calculate the temperature?
A: the actual temperature is the temperature data outputted by FOG divide by 16.
Q: Whether each FOG’s scale factor is different?
A: yes, right. Each FOG’s scale factor is different, but it is close for standard model, for the ODM FOG, the scale factor will change much.
Q: whether the connector and cable length can be selected?
A: yes, no problem, please let us know the connector type and cable length you want, then we can do it, and also different color cable can be selected.
Q: How about the delivery time?
A: for our standard model, if we have them in stock, only need 2~3days to re-test before shipping, if it is out of stock, then need around 2 weeks to arrange the production and tests. For the ODM FOG product, if needing to modify the structure, it will need around 3 weeks to arrange the production and tests.
Q: How to arrange the payment?
A: about the payment, please pay to our company account, the beneficiary’s name: NANJING SKY MEMS TECHNOLOGY CO., LTD. And our email is only @skymems.com to contact with u formally. To notice this to avoid the loss.
Q: what is the different between fiber optic gyro and MEMS gyros?
A: FOGs use the Sagnac effect, which utilizes counter-propagating optical beams and interferometry to measure rotation. FOGs have solid state, all fiber or hybrid fiber construction. Moderately priced, the fiber optical gyros are typically used for industrial and high tactical grade applications, and provide good price to performance value.
The MEMS gyros use the Coriolis Effect, which is based on vibrating mass deflection resulting from rotation. MEMS can be quartz or silicon based in construction and their benefits are low cost, small size/weight. MEMS are typically used in consumer to industrial grade applications.
The FOGs and MEMS gyros have their own advantages, and SkyMEMS can provide both, and can fully consider the application requirements, and provide the right solution for your applications.
