Frequently Asked Questions (Technical FAQ)
Can the USL03-LED be used in washdown environments?
Yes. With a verified IP65 protection class, the USL03-LED is fully sealed against dust ingress and is protected against low-pressure water jets from any direction. This makes it safe for standard industrial cleaning processes and washdowns common in food and chemical processing plants.
What specific fittings does the USL03-LED fit?
The unit is designed for universal versatility on both combined sight/light ports (single-flange) and separate ports. It specifically fits:
- DIN 28120: From nominal size DN 25 and larger.
- DIN 11851: From nominal size DN 65 and larger.
- Visual flow indicators and similar pipeline components.
Why is stainless steel 1.4552 used in construction?
The 1.4552 grade is a high-performance stainless steel often used in glass-to-metal sealing applications. Its inclusion ensures the structural integrity and corrosion resistance required for long-term operation in demanding industrial atmospheres.
