Explosion-Proof Certification Requirements for Packaging

Why does OFSCN’s all-metal structure naturally meet many explosion-proof rating requirements?

OFSCN’s all-metal structure inherently contributes to meeting many explosion-proof rating requirements primarily due to the fundamental properties of fiber optic sensing and the robust nature of the metal packaging.

Fiber optic sensors are intrinsically safe because they operate by transmitting light rather than electricity at the sensing point. This eliminates the risk of electrical sparks or shorts, which are common ignition sources in hazardous and potentially explosive atmospheres.

The all-metal encapsulation further enhances this safety by:

  • Physical Protection: The metal tube or casing provides robust physical protection for the optical fiber and the Fiber Bragg Grating (FBG), safeguarding it from mechanical damage, chemical corrosion, and high temperatures, which can be prevalent in hazardous environments.
  • EMI Immunity: Fiber optic sensors are immune to electromagnetic interference (EMI), which is crucial in industrial settings where electrical equipment can generate strong electromagnetic fields. This immunity helps maintain signal integrity and prevents additional safety risks.

These combined features make OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensors and OFSCN® 500°C Fiber Bragg Grating Temperature Sensors well-suited for applications requiring high reliability and safety in challenging conditions, including those demanding explosion-proof considerations.
