Elesa+Ganter 113193-KN HCK.127-ZN-M12-FKM-GL-P-E-NC-80-NC-KN Oil Level Indicator

Overview

The Elesa+Ganter 113193-KN oil level indicator, with the complete designation HCK.127-ZN-M12-FKM-GL-P-E-NC-80-NC-KN, is a protected column level indicator for hydraulic reservoirs, lubrication units and industrial machine tanks. It combines visual fluid level checking with normally closed electrical monitoring for both minimum level and maximum temperature.

The HCK.127 size refers to a 127 mm hole centre distance. This compact format is widely used where operators need a direct level reading without opening the tank. The model includes zinc-plated steel fixing elements, M12 connection, FKM sealing rings and a borosilicate glass tube. The KN suffix identifies the knob-style fastening version.

Electrical Monitoring Concept

The E-NC-80-NC configuration provides a normally closed minimum level contact and a normally closed temperature contact set at 80°C. The level contact opens when the minimum level threshold is reached. The temperature contact opens when the fluid reaches the preset 80°C point. This arrangement is practical for systems where signal loss should be treated as a warning condition.

Practical Engineering Value

The Elesa+Ganter 113193-KN HCK.127-ZN-M12-FKM-GL-P-E-NC-80-NC-KN oil level indicator supports both manual inspection and automatic machine feedback. Maintenance teams can visually check oil level during routine service, while the electrical contacts can be connected to alarms, indicator lights or PLC inputs. This helps reduce the risk of running equipment with insufficient oil or excessive fluid temperature.

Material Advantages

FKM seals are valuable in applications where temperature resistance and fluid compatibility are important. The GL borosilicate glass tube supports clear visibility and is suitable for oil, water and water/glycol-based solutions when the actual operating conditions are confirmed. The front protection improves durability in industrial environments where accidental contact, dirt or mechanical exposure may occur.

Elesa+Ganter 113193-KN FAQ

What makes 113193-KN different from 113193?

The main technical structure is similar, but 113193-KN includes the KN fastening execution, which appears at the end of the stock name.

How does the NC temperature contact work?

The normally closed temperature contact opens when the fluid reaches the preset 80°C point, allowing the control system to detect an over-temperature condition.

Is the indicator suitable for automated monitoring?

Yes. It can provide electrical level and temperature signals to a control panel, alarm unit or PLC input when correctly integrated.

Why use borosilicate glass?

Borosilicate glass offers clear visibility and improved compatibility for oil, water and water/glycol-based fluids compared with many basic transparent materials.
