Elesa+Ganter 113211 HCK.127-ZN-M12-FKM-GL-P-EHT-NC-80-NC Electrical Oil Level Indicator

The Elesa+Ganter 113211 electrical oil level indicator is a technical monitoring component for hydraulic reservoirs, lubrication tanks and industrial fluid systems. Listed as HCK.127-ZN-M12-FKM-GL-P-EHT-NC-80-NC, this model is configured with normally closed contacts for both minimum level detection and 80°C temperature monitoring.

What Makes This Version Different?

The key distinction of this model is the NC contact logic. In a normally closed configuration, the circuit is closed during normal operating conditions and changes state when the monitored condition is reached. This approach is often preferred in control systems where signal loss, cable damage or abnormal status must be easier to detect. For safety-conscious maintenance teams, NC logic can support a more diagnostic-friendly installation.

Construction and Fluid Compatibility

This HCK.127 model uses a 127 mm centre distance and M12 connection. The GL construction supports use with oil, water and water/glycol-based fluids. The Pyrex glass tube gives operators a clear visual reading of the fluid level, while the FKM O-ring helps maintain sealing performance under higher temperature or chemically demanding conditions. Its column design is practical because it combines visibility, electrical output and temperature monitoring in a single part.

Industrial Use Cases

The Elesa+Ganter 113211 HCK.127 electrical oil level indicator can be used in hydraulic power units, machine tools, lubrication reservoirs, cooling modules and equipment where fluid shortage or high temperature may damage pumps, valves or seals. The 80°C NC temperature contact can be used as an alarm input for control panels or maintenance warning systems.

Elesa+Ganter 113211 FAQ

What does NC-80-NC mean?

It means the level contact is normally closed, and the 80°C temperature contact is also normally closed.

When is an NC contact useful?

An NC contact is useful when the control design benefits from a closed circuit during normal operation and a signal change during a fault or limit condition.

Does this model include visual level checking?

Yes. The column-style transparent tube allows direct visual inspection of the reservoir level.

Can it help prevent hydraulic system damage?

Yes. By signalling low fluid level and high temperature, it can support preventive action before a pump, seal or hydraulic component is damaged.

Is FKM better for demanding applications?

FKM is commonly selected where resistance to heat and industrial fluids is important, making it suitable for more demanding operating environments.
