In a nutshell? i cannot seem to find a lot of information online about these. Could someone please help?
thanks!
thanks!
Topher925 said:It depends on the type of sensor. The most popular is probably the diaphragm design. They are basically just a regular fiber with a diaphragm on the end that is normal to the fiber. Light is sent to the end of a fiber via a fiber coupler and received by a photodiode/phototransistor. As the pressure increases, the diaphragm deforms and causes more light from the fiber to deflect thereby lowering the return intensity/optical path.
Fiber optic pressure sensors work by using a fiber optic cable that is sensitive to changes in pressure. The cable is designed to deform when pressure is applied, which changes the way light travels through it. This change in light can be measured and converted into a pressure reading.
Fiber optic pressure sensors are highly accurate, with a resolution as low as 0.01% of full scale. They also have a wide measurement range and can withstand high pressures without losing accuracy.
Fiber optic pressure sensors have several advantages over traditional pressure sensors. They are immune to electromagnetic interference, have a fast response time, and can be used in harsh environments such as high temperatures and corrosive chemicals.
Fiber optic pressure sensors have several advantages over other types of pressure sensors, such as strain gauge and piezoelectric sensors. They have a smaller size, higher accuracy, and are not affected by electrical interference. They also have a wider measurement range and can be used in more extreme environments.
Yes, fiber optic pressure sensors are commonly used in medical applications such as blood pressure monitoring, catheter pressure measurement, and respiratory monitoring. They are biocompatible, sterilizable, and can provide accurate and real-time pressure readings.
