Elesa+Ganter 113199 HCK.127 Oil Level Indicator
The Elesa+Ganter 113199 oil level indicator, listed as HCK.127-ZN-M12-FKM-GL-P-E-NC-STL, is an industrial column level indicator developed for accurate fluid level monitoring in hydraulic and lubrication systems. It is built for applications where visibility, material compatibility and electrical level signalling are all important.
Product Function
This model belongs to the HCK.127 series and includes an electrical normally closed contact. The NC contact is commonly selected when the control logic requires a closed circuit during normal operation. If the monitored level changes and reaches the switching point, the contact status changes, allowing the machine or control panel to detect the condition.
The Elesa+Ganter 113199 HCK.127 oil level indicator uses an M12 connection, which is widely preferred in industrial automation because it supports clean, secure and service-friendly wiring. The GL configuration supports oil and glycol-based solutions, while the FKM seal selection improves resistance in demanding fluid environments.
Construction and Reliability
A column level indicator must remain readable under daily operating conditions. This HCK.127 version offers a clear level display, robust mounting concept and materials selected for industrial use. The combination of transparent level viewing and electrical signal output gives maintenance teams more than a simple sight glass. It provides a practical monitoring point that can support predictive maintenance routines.
In hydraulic tanks, low fluid levels can cause pump damage, overheating, pressure instability and increased wear. A correctly installed indicator helps operators notice these risks early. The NC contact version is especially useful in safety-conscious control designs where circuit continuity is part of the monitoring logic.
Typical Application Areas
This product is suitable for hydraulic power units, machine tools, forming equipment, industrial presses, cooling and lubrication units, and reservoir-based machinery. It is a strong option where a compact, reliable and technically specified oil level indicator is needed.

Frequently Asked Questions
What is the main purpose of the Elesa+Ganter 113199 HCK.127 oil level indicator?
Its main purpose is to show the fluid level visually and provide an electrical level signal through its normally closed contact. This helps operators and control systems monitor tank level more effectively.
What does NC mean in this product code?
NC means normally closed. The electrical contact is closed in its normal state and opens or changes status when the switching condition is reached.
Why would an engineer choose an NC version instead of an NO version?
An NC version is often preferred when the system is designed to detect a broken circuit, disconnected cable or level change more actively. The best choice depends on the machine’s control logic.
What fluids is this indicator suitable for?
The GL configuration is designed for oil and glycol-based solutions. For unusual fluids, high pressure or special temperature conditions, compatibility should be checked before installation.
Does the M12 connection make maintenance easier?
Yes. M12 connectors are widely used in industrial environments because they allow secure electrical connection, easier replacement and cleaner wiring compared with loose cable arrangements.
