Elesa+Ganter 113791-KN HCK.127 Oil Level Indicator

Elesa+Ganter 113791-KN oil level indicator, with the model code HCK.127-A4-M12-FKM-GL-P-E-NO-80-NO-KN, is an electrical column oil level indicator developed for hydraulic tanks, lubrication systems, and industrial reservoirs. It combines visual level checking with electrical level and temperature signalling, helping operators move from simple inspection toward more controlled condition monitoring.

Product Type and Core Specification

This model belongs to the HCK.127 family, meaning it uses a 127 mm hole-centre distance. The M12 connection provides a robust mounting format for tank installation. The A4 designation is associated with stainless steel fixing hardware, commonly selected for environments where corrosion resistance and mechanical reliability are important. FKM sealing rings provide improved resistance against heat and industrial fluids, while the GL borosilicate glass tube gives a clear view of the oil level.

The P version includes a polyamide-based technopolymer float. This float is part of the level monitoring system and supports the electrical switching function. The E-NO-80-NO configuration indicates normally open level contact logic and a normally open 80°C temperature contact.

Why Normally Open Contacts Matter

A normally open contact is useful when the machine control system is designed to receive a signal only after a defined level or temperature condition occurs. In this model, the NO level contact can help detect a fluid level condition, while the NO temperature contact at 80°C can support overheating prevention. This is especially valuable in hydraulic units where low oil level or excessive oil temperature may increase wear, reduce performance, or cause unplanned downtime.

Engineering Benefits in Daily Use

The Elesa+Ganter 113791-KN HCK.127-A4-M12-FKM-GL-P-E-NO-80-NO-KN oil level indicator is helpful for maintenance teams because it gives two layers of information. The operator can visually inspect the reservoir through the transparent glass tube, while the electrical contacts can be connected to a control panel, relay, PLC, or alarm circuit. This combination supports faster diagnostics and more reliable machine protection.
