Elesa+Ganter 113215 HCK.127-ZN-M12-FKM-GL-P-EHT-NO-STL Oil Electrical Level Indicator

The Elesa+Ganter 113215 HCK.127-ZN-M12-FKM-GL-P-EHT-NO-STL oil electrical level indicator is designed for hydraulic reservoirs where fluid visibility, minimum level monitoring and temperature reading are required in one compact component. It belongs to the HCK-E family of column level indicators and is especially relevant for systems using oil, water, or water-glycol based solutions.

Technical Overview

This model uses a 127 mm hole centre distance and M12 mounting. The ZN execution indicates zinc-plated steel screws, while the FKM sealing rings are suitable for higher continuous working temperatures than standard NBR versions. Its GL transparent tubular window is made from borosilicate glass, a practical choice when the application involves oil, water, or water-glycol mixtures. The removable P front protection in polycarbonate helps protect the viewing area and supports easier cleaning during maintenance.

Level and Temperature Monitoring

The EHT configuration uses a glass-fibre reinforced polyamide float designed for higher temperature use. The NO contact means the minimum level electrical contact closes when the fluid reaches the minimum threshold. The STL suffix refers to a PT100 temperature electrical probe, allowing the system to read temperature through resistance variation. This makes the indicator useful in hydraulic power units, lubrication systems, industrial tanks and process equipment where both level and temperature are operationally important.

Application Notes

Because the float includes a magnetic element, installation near strong magnetic fields should be avoided. The indicator is commonly selected where maintenance teams need a direct visual check and an electrical signal for automation or machine protection.

Elesa+Ganter 113215 FAQ

What is the Elesa+Ganter 113215 used for?

It is used to monitor fluid level and temperature in hydraulic tanks, oil reservoirs and systems where a minimum level signal is needed.

What does NO mean in this model?

NO means normally open. In this configuration, the electrical contact closes when the minimum level is reached.

Why is the GL tube important?

The GL borosilicate glass tube is suitable for oil, water and water-glycol based solutions, making the indicator more versatile than oil-only versions.

What does STL indicate?

STL identifies the PT100 temperature electrical probe, which allows temperature monitoring through resistance measurement.

Is this model suitable for higher temperatures?

Yes. The FKM sealing and EHT float configuration make it appropriate for higher-temperature operating environments, provided the actual fluid and system conditions are verified.
