Elesa+Ganter 113751-KN Electrical Level Indicator

Technical Overview

Elesa+Ganter 113751-KN electrical column level indicator is listed as HCK.127-A4-M12-FKM-PC-P-E-NC-80-NC-KN. It combines a visual column level indicator with electrical level and temperature monitoring. The HCK.127 construction uses a 127 mm hole centre distance and M12 fixing thread, which makes it suitable for standardized installation on hydraulic reservoirs and oil tanks.

The model includes FKM synthetic rubber O-rings, selected for continuous working temperatures up to 130°C. Its transparent PC tube is designed for oil level visibility, and the removable polycarbonate front protection supports easier inspection and cleaning. The A4 stainless variant is relevant where environmental durability and corrosion resistance are important selection factors.

Electrical Monitoring Behavior

The NC minimum level contact is normally closed and opens when the minimum oil level is reached. The 80-NC temperature sensor also opens when the preset 80°C temperature condition is reached. This behavior is useful for control panels, PLC input systems and alarm circuits where open-contact status can represent a defined warning state.

In practical use, the Elesa+Ganter 113751-KN electrical column level indicator supports both manual inspection and automated condition monitoring. Engineers usually evaluate this part by checking fluid type, sealing material, connection thread, sensor logic, operating temperature and reservoir wall compatibility.

FAQ

What is Elesa+Ganter 113751-KN used for?

It is used to monitor oil level visually and electrically in hydraulic reservoirs, with an additional 80°C temperature warning function.

What is the difference between 113751 and 113751-KN?

Both follow the same HCK.127 electrical level indicator concept, but the KN suffix identifies a specific ordering execution. The 113751-KN code also includes the A4 stainless configuration.

Why is FKM important?

FKM improves resistance at higher working temperatures and is commonly selected when the sealing specification is more demanding than standard rubber options.

Does the PC tube work with glycol mixtures?

The PC tube version is intended for oil. For water or water/glycol-based fluids, the GL tube version should be evaluated.
