Elesa+Ganter 113209 HCK.127-ZN-M12-FKM-GL-P-EHT-NO-80-NO Electrical Oil Level Indicator

The Elesa+Ganter 113209 electrical oil level indicator is a column-type monitoring component designed for hydraulic tanks, lubrication units and industrial fluid reservoirs where both visual level control and electrical signal output are required. Identified by the stock name HCK.127-ZN-M12-FKM-GL-P-EHT-NO-80-NO, this model combines a 127 mm centre distance, M12 connection, FKM sealing and a configuration suitable for oil, water and water/glycol-based solutions.

Technical Overview

This indicator belongs to the HCK-E style of electrical column level indicators. The transparent column allows operators to visually check the fluid level, while the electrical contact supports machine-side monitoring. The “NO” level contact means the electrical contact is normally open and changes state when the minimum level point is reached. The “80-NO” temperature configuration indicates a normally open temperature contact set around 80°C, making the unit useful where overheating warnings are part of the maintenance strategy.

Material and Application Benefits

The Pyrex glass tube improves resistance for glycol-based fluids, while FKM sealing supports higher chemical and temperature resistance compared with standard rubber sealing in demanding environments. The zinc-plated mounting hardware and technopolymer end blocks help create a robust assembly for industrial use. For technicians, the main benefit is simple: one component can support visual inspection, low-level signalling and temperature threshold monitoring.

Where It Is Commonly Used

The Elesa+Ganter 113209 HCK.127 electrical oil level indicator is commonly selected for hydraulic power packs, machine tool lubrication systems, cooling circuits and compact reservoir assemblies. It is especially practical where a PLC, relay or control panel must receive a clear status change before a pump runs dry or fluid temperature rises beyond a planned limit.

Elesa+Ganter 113209 FAQ

What is the main function of the Elesa+Ganter 113209 indicator?

It provides visual fluid level monitoring and electrical signalling for minimum level and temperature threshold control.

What does NO-80-NO mean?

The first NO refers to the normally open level contact. The 80-NO section refers to a normally open temperature contact set around 80°C.

Is this model suitable for glycol-based solutions?

Yes. The GL configuration and Pyrex glass tube make it appropriate for applications involving oil, water and water/glycol-based fluids, subject to real operating conditions.

Why is FKM sealing important?

FKM sealing offers improved resistance to temperature and many industrial fluids, which helps increase reliability in demanding hydraulic systems.

Can it be used in automated systems?

Yes. The electrical contact output allows the indicator to be integrated into machine control circuits, alarm systems or preventive maintenance logic.
