Elesa+Ganter 113759 HCK.127-SST316-M12-FKM-PC-P-EHT-NO Electrical Oil Level Indicator

The Elesa+Ganter 113759 HCK.127-SST316-M12-FKM-PC-P-EHT-NO electrical oil level indicator is built for hydraulic systems that require level monitoring and temperature-related electrical feedback. It combines the HCK.127 column format with AISI 316 stainless steel fixing parts, FKM sealing, polycarbonate visibility and an NO electrical configuration.

Technical Profile

This model uses M12 mounting, a 127 mm hole centre distance and a 164 mm overall length in the HCK.127 family. The transparent PC tube provides oil level visibility, while the removable PC front protection helps protect the viewing area from dirt, impact and routine workshop exposure. The SST316 execution gives the indicator stronger corrosion resistance compared with standard zinc-plated versions.

NO Contact and EHT Function

The NO configuration means normally open contact logic. In typical monitoring circuits, the contact changes when the defined level or temperature condition is reached. The EHT reference indicates an electrical temperature probe configuration, making this model useful where fluid level and oil temperature behaviour need to be considered together.

Common Applications

Engineers may specify this product for hydraulic power units, industrial oil reservoirs, lubrication equipment, production machinery and test benches. It is especially helpful where operators want a clean visual column and the control system needs an electrical status signal.

Elesa+Ganter 113759 FAQ

What makes Elesa+Ganter 113759 different from a standard visual level indicator?

It is not only a visual indicator. It also includes electrical monitoring features, allowing the system to react when a defined level or temperature condition is reached.

What does NO mean?

NO means normally open. The electrical contact is open in its normal state and changes when the switching condition occurs.

Why is FKM used in this model?

FKM is selected for stronger resistance to heat and many industrial oils, making it suitable for higher-demand hydraulic applications.

Can this indicator be used with glycol-based fluids?

The PC version is mainly associated with oil use. For water or glycol-based solutions, compatibility should be checked carefully against the correct HCK execution and real operating conditions.
