Intrinsically Safe VR Speed Sensors
Intrinsic safety has become an increasingly popular approach for handling sensing requirements in hazardous locations. These sensors are intrinsically safe versions of Motion Sensors Hermetically Sealed VR Sensors or Epoxy Encapsulated VR Sensors.
- Features & Specifications
- Standard Models
Type
Variable reluctance (VR) or inductive type
Warranty
Unconditional one (1) year warranty if used within specifications
Physical Features
- Body material: 300 series stainless steel (locknut included)
- Encapsulation: hermetically sealed, heli-arc welded construction or epoxy encapsulation
- Magnet that resists demagnetization
