Elesa+Ganter 11118 HCV.127-E-STL-NC-M12 Column Level Indicator
The Elesa+Ganter 11118 column level indicator, supplied under the code HCV.127-E-STL-NC-M12, is designed for hydraulic systems that need visual oil level control and an electrical minimum-level signal. It is a practical choice for machinery where operators need a clear sightline and control systems need a dependable signal.
Technical Construction
The indicator body is made from transparent PA-T technopolymer, selected for mechanical strength and resistance to oils, solvents and hydrocarbon-based fluids. The model includes zinc-plated steel screws, nuts and washers, plus sealing elements designed for reservoir wall installation. Its float contains a magnetic element that activates the internal reed contact when the oil level drops to the defined minimum point.
The NC configuration means the electrical contact is normally closed and opens when the minimum level is reached. This behaviour is often preferred in safety-conscious systems because a broken wire or open circuit can be easier to identify in a monitored control loop. The STL version also provides an electrical temperature probe based on platinum resistance, supporting temperature monitoring through compatible measuring equipment.
Why This Indicator Matters
In hydraulic equipment, low oil level can lead to overheating, cavitation, pump wear and unplanned downtime. The Elesa+Ganter 11118 HCV.127-E-STL-NC-M12 column level indicator supports preventive maintenance by making oil level visible and electrically traceable. Its M12 configuration and 127 mm pitch make it suitable for compact reservoirs and standardized panel layouts.
Recommended Use

Elesa+Ganter 11118 FAQ
What is the product type of HCV.127-E-STL-NC-M12?
It is an electrical column level indicator for hydraulic systems, combining oil level visibility with minimum-level signalling.
How does the NC contact work?
The contact remains closed during normal operation and opens when the minimum oil level is reached.
Does the indicator measure temperature directly?
It includes a temperature probe that changes electrical resistance according to temperature, allowing compatible instruments to interpret the value.
What material is the transparent body made from?
The body is made from transparent polyamide-based technopolymer, chosen for visibility and resistance to common industrial oils.
Why is 127 mm important?
It refers to the mounting pitch, helping engineers match the indicator to the reservoir hole spacing during installation or replacement.
