Elesa+Ganter 11131 Column Level Indicator: HCV.127-E-NO-M12 Technical Guide
The Elesa+Ganter 11131 column level indicator, known as HCV.127-E-NO-M12, is designed for hydraulic reservoirs and fluid tanks where both visual level reading and electrical minimum-level signalling are required. It combines a transparent technopolymer body with an integrated electrical contact, helping operators detect low fluid levels before they become a system risk.
Technical Structure
This model has a 127 mm mounting centre distance and an overall length of approximately 153 mm. It uses an M12 connection and a normally open contact configuration. In operation, the NO contact closes when the fluid reaches the minimum level threshold. This makes the indicator suitable for warning circuits, machine protection systems and maintenance alerts.
Material and Visibility
The HCV-E range uses transparent polyamide-based technopolymer that is resistant to oils, solvents and many industrial fluids. Its lens effect improves level visibility from different viewing angles, while the contrast screen helps operators read the fluid level more easily. The internal float includes a magnetic element that activates the electrical contact at the defined threshold.
Where the HCV.127-E-NO-M12 Fits Best
The Elesa+Ganter 11131 column level indicator is well suited to hydraulic power units, oil tanks, industrial reservoirs, lubrication systems and machinery where low fluid level must be identified quickly. It is particularly useful when visual inspection alone is not enough and an electrical signal is needed for alarms or control logic.
Operational Notes
The maximum continuous working temperature is 90°C with oil. Floating performance is intended for fluids with suitable density, and the product should be checked under real working conditions when used with fluids other than mineral oils. It should also not be installed near strong magnetic fields, as the sensor function relies on magnetic activation.

Elesa+Ganter 11131 FAQ
What is the Elesa+Ganter 11131 HCV.127-E-NO-M12 used for?
It is used to monitor fluid level in tanks and reservoirs. It provides a visual level reading and an electrical signal when the minimum level is reached.
What does NO contact mean?
NO means normally open. In this model, the electrical contact closes when the fluid reaches the minimum level threshold, allowing the system to trigger an alarm or control response.
Is this product only a visual indicator?
No. It is both a visual column level indicator and an electrical level indicator. That makes it more useful in automated or safety-conscious systems.
Why is the M12 connector important?
The M12 connector supports practical integration into industrial wiring systems. It helps simplify installation and maintenance compared with less standardised connection methods.
