Elesa+Ganter 113185-KN HCK.127-ZN-M12-FKM-GL-P-E-NC-KN Electrical Level Indicator

The Elesa+Ganter 113185-KN HCK.127-ZN-M12-FKM-GL-P-E-NC-KN electrical level indicator is engineered for applications where fluid level must be seen clearly and monitored electrically. It is part of the HCK.127 family and is commonly used on hydraulic reservoirs, lubrication systems and industrial machine assemblies.

Technical Profile

This model uses a 127 mm hole centre distance and an M12 mounting configuration. The ZN hardware indicates zinc-plated steel screws, nuts and washers. FKM sealing rings help support higher temperature service, while the GL borosilicate glass tube is suitable for oil, water and water-glycol based solutions up to 50%.

The NC-KN version is based on a normally closed minimum-level contact. During normal operation, the circuit remains closed. When the fluid reaches the minimum level, the contact opens. This response can be useful in control systems where an open circuit is interpreted as a warning, stop signal or maintenance alert.

Elesa+Ganter 113185-KN Operational Benefits

The main advantage of this level indicator is that it combines simple visual confirmation with electrical monitoring. Operators can inspect the fluid column directly, while the machine control system can receive a defined signal when the level drops. This dual approach supports preventive maintenance and can help avoid running pumps, valves or hydraulic circuits under poor fluid conditions.

Suitable Applications

The Elesa+Ganter 113185-KN electrical level indicator is a strong fit for compact hydraulic units, production machinery, fluid tanks, test benches, lubrication reservoirs and industrial systems where space is limited but dependable monitoring is still required. The removable polycarbonate front protection supports cleaning, which is helpful in environments exposed to oil mist, dust or machine residue.

Frequently Asked Questions

What makes 113185-KN different from a basic sight glass?

It is not only a visual indicator. It also includes an electrical minimum-level contact, which allows the machine to respond when fluid drops too low.

What does the NC contact do?

The normally closed contact opens at the minimum fluid level. This behaviour is useful for control circuits designed around continuity monitoring.

Is the GL tube suitable for hydraulic oil?

Yes. It is suitable for oil and also for compatible water or water-glycol based solutions up to 50%.

Why is FKM used in this model?

FKM sealing rings are selected for better resistance in higher temperature or more demanding operating environments.

Can this model be used in automated systems?

Yes. Its electrical contact can be integrated into alarms, control panels or PLC-based monitoring systems when wired correctly.
