Elesa+Ganter 114203 HCK.176-ZN-M12-FKM-GL-P-EHT-NC Column Level Indicator
Elesa+Ganter 114203 column level indicator is an industrial liquid level monitoring component used where visual inspection and electrical minimum-level control must work together. The model HCK.176-ZN-M12-FKM-GL-P-EHT-NC is built around a 176 mm centre distance, zinc-plated steel fastening elements, M12 mounting connection, FKM sealing, borosilicate glass level tube, protective front section, high-temperature float system, and normally closed contact logic.
Technical Overview
The HCK.176 structure offers a clear vertical level reading for hydraulic tanks, oil reservoirs, lubrication systems, cooling units, and similar machine assemblies. Its 176 mm centre distance provides a practical reading window without requiring complex level measurement electronics. For many industrial machines, this makes the component a dependable first line of level observation.
ZN identifies zinc-plated steel hardware. This supports mechanical strength during installation and long-term use in standard industrial conditions. The M12 mounting format is widely used in hydraulic tank design, helping maintenance teams replace or specify the component with confidence when the tank interface matches.
FKM Seal and Glass Tube Advantages
FKM sealing is selected for better resistance against heat and many oil-based or industrial fluids. In systems where temperature variation, lubricant exposure, or chemical compatibility are important, FKM can provide a more robust sealing option than basic elastomer materials.
The GL borosilicate glass tube improves visual reliability. Operators can check the liquid level directly, while the protective front element helps shield the reading area from routine workshop contact.
Normally Closed Contact Function
The NC version means the electrical contact is normally closed. When the liquid falls to the defined minimum level, the contact opens. This logic is frequently preferred in monitoring circuits where interruption of the signal must indicate a low-level condition or possible fault state. It can be integrated into control panels, PLC systems, warning lamps, or machine safety logic.

Elesa+Ganter 114203 FAQ
What is Elesa+Ganter 114203 column level indicator designed for?
It is designed for checking and monitoring liquid levels in industrial tanks, especially where visual inspection and electrical low-level detection are both required.
What does NC mean in this model?
NC means normally closed contact. The contact is closed during normal conditions and opens when the liquid reaches the minimum level point.
When should an NC contact be preferred?
An NC contact is often preferred when the control system must recognize an open circuit as a warning condition. This can be useful for fail-aware monitoring designs.
Does the 176 mm centre distance matter?
Yes. The centre distance must match the tank mounting holes. It also determines the visible measuring length available to the operator.
What makes this product suitable for industrial use?
The combination of M12 mounting, zinc-plated steel hardware, FKM sealing, borosilicate glass, protected viewing area, and electrical level contact makes it suitable for demanding machine environments.
