Elesa+Ganter 113191-KN HCK.127-ZN-M12-FKM-GL-P-E-NO-80-NO-KN Oil Level Indicator

Technical Description

The Elesa+Ganter 113191-KN oil level indicator, known by its full stock name HCK.127-ZN-M12-FKM-GL-P-E-NO-80-NO-KN, is a column-type level indicator for hydraulic and lubrication systems. It is designed to provide clear visual fluid level checking and electrical signalling for minimum level and maximum temperature events.

The HCK.127 size uses a 127 mm hole centre distance. This makes it practical for compact reservoirs where maintenance teams need quick external inspection. The code includes ZN zinc-plated steel fixing parts, M12 thread size, FKM sealing rings and a GL borosilicate glass transparent tube. The P execution indicates front protection, while KN refers to the knob-style fastening version.

Normally Open Level and Temperature Monitoring

The E-NO-80-NO section of the product code shows two normally open functions. The minimum level contact closes when the fluid reaches the minimum threshold. The temperature contact closes when the preset 80°C point is reached. This dual monitoring structure is valuable for hydraulic units where low oil level and rising temperature can both indicate operational risk.

Where It Is Used

The Elesa+Ganter 113191-KN HCK.127-ZN-M12-FKM-GL-P-E-NO-80-NO-KN oil level indicator is suitable for hydraulic tanks, machine tools, lubrication reservoirs, industrial automation equipment and power transmission systems. It helps operators see the level directly, while allowing the control panel to receive electrical feedback.

Human-Centred Maintenance Value

In everyday maintenance work, a clear level indicator is more than a simple accessory. It helps technicians make faster decisions, check reservoir status without opening the tank and detect early warning signs before they become downtime. The glass tube supports reliable visibility, and the FKM sealing makes the component suitable for tougher temperature requirements than many standard level indicators.

FAQ

What is the difference between 113191 and 113191-KN?

Both share the same main technical configuration, but the 113191-KN version includes the KN fastening execution, which is reflected in the full product code.

What does the 80-NO part mean?

It indicates a normally open temperature contact that closes when the fluid reaches the preset 80°C temperature point.

Can this model be used in hydraulic oil tanks?

Yes, it is designed for hydraulic and oil reservoir monitoring, provided the fluid, pressure and temperature conditions are suitable.

Why is visual monitoring still important?

Visual monitoring gives technicians immediate confirmation of the fluid level, even when electrical systems are disconnected, under service or being checked manually.
