Elesa+Ganter 113067-KN Electrical Level Indicator for Reliable NC Low-Level Monitoring
Elesa+Ganter 113067-KN electrical level indicator, coded as HCK.127-ZN-M12-NBR-GL-P-E-NC-STL-KN, is a compact HCK-E-STL series component used in hydraulic and lubrication reservoirs where operators need visual level reading, low-level electrical signalling and temperature feedback.
Technical Identity of the Product
This model has a 127 mm hole-centre distance, M12 threaded mounting and a compact level visibility layout. It is especially suitable for machinery where the available tank surface is limited but fluid status still needs to be checked quickly and accurately. The product type is an electrical level indicator, not only a passive sight gauge, because it includes a sensor system for minimum-level detection.
Materials and Design
The assembly ends are manufactured from glass-fibre reinforced polyamide based technopolymer in black colour. The support is aluminium, and the white graduated contrast screen improves readability by creating a clear visual background behind the transparent level column. The GL tube is made from borosilicate glass, which is suitable for oil, water and water/glycol-based solutions.
NBR O-rings are used for sealing, supporting standard hydraulic oil environments and continuous working temperatures up to 100°C. The removable polycarbonate front protection helps shield the tube from dirt and mechanical exposure while allowing cleaning when visibility is reduced.
NC Sensor Logic and STL Temperature Probe
The NC minimum-level contact remains closed during normal operation and opens when the fluid reaches the minimum level. This signal behaviour is often useful in industrial control systems where an open circuit can be interpreted as a warning state. The STL designation refers to the integrated PT100 temperature probe, supporting temperature monitoring alongside level detection.
Why It Matters in Hydraulic Systems
Low oil level can lead to overheating, air intake, pump wear and unstable machine movement. A component such as this helps maintenance teams detect problems earlier. When installed in a visible location, it gives technicians a fast local reading while also allowing the control system to receive an electrical warning.

Elesa+Ganter 113067-KN Frequently Asked Questions
What is Elesa+Ganter 113067-KN electrical level indicator used for?
It is used for visual and electrical monitoring of fluid level in hydraulic reservoirs, lubrication systems and industrial fluid tanks.
How is this model different from a simple oil sight glass?
A simple sight glass only allows visual checking. This model also includes a minimum-level electrical contact and a PT100 temperature probe.
What does the NC function provide?
The NC contact opens when the minimum level is reached, allowing compatible monitoring circuits to detect a low-level condition.
What fluids can be used with the GL version?
The GL borosilicate glass tube is intended for oil, water and water/glycol-based solutions, subject to actual operating conditions.
Why should magnetic fields be avoided?
The sensor uses magnetic float behaviour. Strong magnetic fields near the installation area may interfere with reliable switching performance.
