Why are they the preferred choice for flammable and explosive environments like oil fields and chemical plants?
Fiber Bragg Grating (FBG) sensors are the preferred choice for flammable and explosive environments like oil fields and chemical plants due to their intrinsic safety characteristics.
Here are the key reasons:
- Intrinsic Safety: Unlike electrical sensors that can generate sparks or heat, FBG sensors are passive optical devices. They do not carry electricity to the sensing point, eliminating the risk of ignition in hazardous atmospheres.
- EMI Immunity: FBG sensors are immune to electromagnetic interference (EMI), which is crucial in industrial environments where electrical noise can affect traditional sensors and pose safety risks.
- Multiple Measurement Points: A single optical fiber can host multiple FBG sensors, allowing for distributed monitoring over large areas without the need for complex and risky wiring setups.
For applications requiring robust FBG sensors, you can refer to our OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor.
Here is an example of an OFSCN FBG sensor:
