Elesa+Ganter 113757-KN HCK.127-A4-M12-FKM-PC-P-E-NC-STL-KN Electrical Oil Level Indicator

The Elesa+Ganter 113757-KN HCK.127-A4-M12-FKM-PC-P-E-NC-STL-KN electrical oil level indicator is a column-type oil level indicator developed for applications where visual checking and electrical minimum-level monitoring are both required. Its HCK.127 structure provides a 127 mm hole centre distance, M12 mounting and a compact installation profile for industrial hydraulic tanks.

Technical Construction

This version includes a transparent polycarbonate tube, polycarbonate front protection, FKM sealing rings and stainless steel fixing hardware. The A4 reference is associated with stainless steel execution, while the M12 connection supports robust mechanical mounting. The integrated electrical level sensor uses an NC contact logic, meaning the system can be wired for fail-aware monitoring in many industrial control layouts.

Practical Use in Hydraulic Systems

This indicator is useful on hydraulic power packs, oil tanks, lubrication units and machine tools where oil level must be checked quickly during maintenance rounds. The white graduated contrast screen improves visibility, and the electrical output can support alarms or interlocks when the fluid level reaches the minimum switching point.

Why Engineers Select This Model

The product gives maintenance teams two layers of information: direct visual level reading and electrical status feedback. FKM sealing supports higher thermal resistance, while the PC window is a practical choice for oil service. For additional product-family context, visit Elesa+Ganter technical components.

Elesa+Ganter 113757-KN FAQ

What is the product type of Elesa+Ganter 113757-KN?

It is an electrical oil level indicator, also known as an electrical column level indicator, used for oil reservoir monitoring.

What does the HCK.127 size indicate?

HCK.127 indicates the 127 mm column size, including the corresponding mounting geometry and hole centre distance used in the HCK series.

Why does this model use a polycarbonate tube?

Polycarbonate offers good transparency and impact resistance for oil level visibility. It allows operators to inspect the fluid level without opening the reservoir.

Is the NC contact useful for safety monitoring?

Yes. A normally closed contact is often preferred where loss of signal or level change should be easy to detect in a control system.
