Elesa+Ganter 111041-NP HCK.381-ZN-M12-NBR-PC-NP Oil Level Indicator

Technical Overview

The Elesa+Ganter 111041-NP HCK.381-ZN-M12-NBR-PC-NP oil level indicator is a visual column level indicator for hydraulic oil and glycol-based solutions. It shares the 381 mm format with the protected version, but the NP designation means it is supplied without transparent front protection.

This makes the product suitable for installations where the indicator is placed in a safer, recessed, or low-impact area. Without the front protection, the visual reading remains direct and clear, while the overall configuration still supports dependable tank level observation. The M12 fixing format, NBR sealing, and HCK body design make it a practical option for industrial fluid systems.

Best-Fit Applications

The Elesa+Ganter 111041-NP HCK.381-ZN-M12-NBR-PC-NP oil level indicator is commonly relevant for hydraulic reservoirs, lubrication systems, compact machinery, service panels, and equipment where the indicator is not exposed to frequent contact. It helps maintenance teams confirm fluid level during inspections without opening the reservoir.

Protected vs Non-Protected Version

The key difference between this NP version and the PC-P version is the absence of the protective front shield. If the indicator is exposed to knocks, tools, or operator movement, a protected version may be more appropriate. If the installation position is controlled and visibility is the main priority, the NP version can be a clean and efficient choice.

FAQ

What does NP mean in Elesa+Ganter 111041-NP?

NP means the indicator is supplied without transparent front protection. It is intended for locations where impact risk is limited.

Is this still suitable for hydraulic oil?

Yes, the HCK series is designed for oil and glycol-based solutions, provided the fluid is compatible with the sealing and body materials.

When should I avoid the NP version?

Avoid it in exposed areas where tools, machine parts, or operators may accidentally hit the indicator. In those cases, a protected PC-P version is usually safer.

Does the 381 mm size improve readability?

Yes. The longer indicator body provides a broader visual range, which can help operators monitor fluid level changes more comfortably.
