FAQ
Why monocrystalline silicon sensors have such high accuracy?
Compared with diffused silicon and ceramics, single crystal silicon has a higher resistance strain sensitivity coefficient. Under the same input, its signal output can be higher than the output of the metal strain gauge, usually 10-100 times , and the input signal can be sensitive to the 10^-6 level or even the 10^-8 level.
What is monocrystalline silicon used for?
Silicon single crystal is used as a semiconductor device mainly because it easily forms a SiO2 (oxide) film on the crystal surface and has excellent stability and insulating properties.
What are the causes of zero point drift?
Zero drift or bias describes gradual change in the scale zero of a measuring instrument. And the main factor of this change is ambient condition. Most importantly, this influence will result in a constant error in the entire measurement range of the instrument. Help of calibration technology, the calibration commands can recover the effects of zero drift on site.
