Can Hydraulic oil level sight glass AWO1 be mounted on curved or angled tank side walls without affecting visibility?

Yes . Hydraulic oil level sight glass AWO1 can be mounted on curved or angled tank side walls without materially affecting visibility. The inspection window is spherical in shape, which specifically permits side observation; this geometry compensates for nonâperpendicular mounting and preserves a usable viewing angle. Practical points to ensure good visibility: - Match the inspection opening diameter (D) to the required field of view and tank curvature so the sight glass seats flush and the polyamide lens remains unobstructed. - Ensure the mounting surface provides a consistent seal with the fiber washer (guarnital) to avoid gaps that could misalign the lens. - Stay within the operating temperature range (0Â°C to +80Â°C) and use the recommended aluminum body to maintain mechanical stability on curved surfaces. If the tank curvature is extreme, verify clearance and sightline on a mock fit; for very shallow angles, consider adjusting the position or using a larger D to maximize visibility.

Is Hydraulic oil level sight glass AWO1 suitable for use with heavy-duty hydraulic oils or additives that may affect materials?

Hydraulic oil level sight glass AWO1 may have limitations with heavy-duty hydraulic oils or additives that can attack materials. Its inspection opening is made of polyamide, the body is aluminum, and the washer is fiber-based (guarnital). Polyamide and aluminum have varying chemical resistances: some aggressive additives, esters, or high-aromatic fluids can cause swelling, embrittlement, or corrosion over time. Operating temperature range 0Â°C to +80Â°C also limits use with high-temperature fluids. Before use with specialized heavy-duty oils or additives, verify chemical compatibility of polyamide, aluminum and the fiber washer with the specific fluid and additive package; if compatibility data are unavailable, consult the supplier or choose a sight glass specified for aggressive fluids.

How frequently should Hydraulic oil level sight glass AWO1 be inspected and maintained to ensure reliable level monitoring?

Hydraulic oil level sight glass AWO1 should be inspected and maintained at regular short intervals to ensure reliable level monitoring. Recommended practice: - Visual check: daily or before each machine shift. verify the sight glass is clean, unobstructed, and the oil level is clearly visible through the spherical inspection opening. - Functional inspection: weekly. confirm the sight glass housing (aluminum body) and polyamide inspection opening show no cracks, clouding, crazing or deformation that could distort level reading. - Seal and fastening check: monthly. inspect the guarnital (fiber) washer and mounting for leaks, corrosion or loosening; tighten fittings and replace the fiber washer if any wear or seepage is detected. - Temperature-related checks: after any exposure outside the 0Â°C to +80Â°C range or after thermal cycling. re-inspect for material embrittlement or seal failure, since polyamide and fiber washer properties can degrade. - Replacement schedule: consider replacing the polyamide inspection opening and fiber washer every 12 months in heavy-duty or harsh environments (high vibration, contamination, extreme temperatures); otherwise replace upon visible wear or compromised sealing. - Cleaning: clean the sight glass with a compatible non-abrasive solvent as needed (at least monthly) to maintain transparency; avoid solvents that attack polyamide or the fiber washer. - Recordkeeping: log inspections and any maintenance actions to detect trends (fogging, leaks, repeated damage) and adjust intervals accordingly. Following these intervals will help ensure Hydraulic oil level sight glass AWO1 provides reliable, accurate level monitoring.
