REL01 Intrinsically Safe Luminaire for Rectangular & Longitudinal Sight Glasses
The REL01 intrinsically safe luminaire is engineered for targeted illumination of rectangular and longitudinal sight glasses, providing reliable lighting for the interior of tanks, hoppers, silos, agitators, reactors, and visual flow indicators in potentially explosive environments. Its compact, side-mount design makes it ideal for food processing and hygienic applications where clear process visibility and strict safety compliance are critical.
Designed to fit snugly along the length of the sight glass, the REL01 mounts directly onto the cover flange using just two screws, delivering clean, uniform illumination without increasing the overall footprint of the assembly.
Explosion Protection & Intrinsic Safety
- Ex II 2G Ex ia C T4/T5/T6 – Intrinsically safe for gas hazardous areas
- Ex I M2 Ex ia I Mb – Intrinsically safe for mining applications
- Suitable for installation in explosion hazardous areas, when connected to an intrinsically safe power supply circuit
Design & Mounting
- Optimised for rectangular / longitudinal sight glasses
- Length: 250 mm – designed to sit snugly along the sightglass edge
- Supplied ready for fitting – two screws fix directly to the cover flange
- Low-profile form factor maintains clean, compact assembly geometry
Typical Applications
- Illumination of rectangular and longitudinal sight glasses
- Tanks, hoppers, silos, agitators, and reactors
- Visual flow indicators and process inspection points
- Food, beverage, pharmaceutical, and fine chemical processing
Electrical Specifications
