Elesa+Ganter 113183 HCK.127-ZN-M12-FKM-GL-P-E-NO Electrical Level Indicator

The Elesa+Ganter 113183 HCK.127-ZN-M12-FKM-GL-P-E-NO electrical level indicator is designed for clear, dependable monitoring of fluid level in hydraulic systems, lubrication units, reservoirs and industrial machinery. Its 127 mm hole centre distance, M12 connection size and integrated minimum-level electrical sensor make it a practical choice where visual inspection and signal-based level monitoring are both required.

Technical Overview

This HCK.127 configuration uses zinc-plated steel fixing hardware, FKM sealing rings and a borosilicate glass transparent tube. The GL tube version is suitable for oil, water and water-glycol based solutions up to 50%, making it more flexible than oil-only indicator designs. The FKM sealing material supports higher continuous working temperatures than standard NBR versions, which is useful in systems exposed to heat, fluid ageing or demanding operating cycles.

The NO designation means “normally open”. In practical terms, the electrical contact closes when the fluid reaches the minimum level threshold. This makes the unit suitable for alert circuits, machine interlocks, warning lights or PLC inputs where a signal is required only when the level becomes too low.

Elesa+Ganter 113183 Where It Is Commonly Used

This oil level indicator is often specified for hydraulic power packs, mobile machinery reservoirs, industrial presses, machine tools, lubrication skids and equipment where maintenance teams need a direct view of the level column. The transparent front protection helps keep the reading area clean, while the compact HCK.127 size supports installations where panel space is limited.

Why This Configuration Matters

The combination of FKM, borosilicate glass and NO electrical output gives this model a balanced profile for reliability and system integration. Engineers may choose it when the application involves glycol-based fluids, elevated temperature exposure or a need for a simple low-level signal.

Elesa+Ganter 113183 Frequently Asked Questions

What is the Elesa+Ganter 113183 used for?

It is used to visually monitor fluid level and provide an electrical signal when the minimum level is reached in tanks, hydraulic reservoirs and lubrication systems.

What does NO mean on this model?

NO means normally open. The contact closes when the fluid reaches the minimum level, allowing the system to trigger an alarm or machine response.

Is this model suitable for glycol-based fluids?

Yes. The GL borosilicate glass tube version is suitable for oil, water and water-glycol based solutions up to 50%, provided the real operating conditions are checked.

Why is FKM important?

FKM is a higher-temperature sealing material compared with many standard rubber seals. It is useful where the system may run warmer or where chemical resistance is important.

Can it be connected to a control system?

Yes. The minimum level sensor can be wired into alarms, control panels or PLC inputs, depending on the machine’s electrical design.
