Elesa+Ganter 11123-KN Column Level Indicator for Hydraulic Oil Monitoring

The Elesa+Ganter 11123-KN column level indicator, also known by the manufacturer code HCV.254-ST-NC-M12-KN, is designed for clear and reliable monitoring of oil level and temperature conditions in hydraulic reservoirs. It belongs to the HCV.254 family, a widely used range of column level indicators for industrial hydraulic systems where visual control and electrical signalling are both important.

Technical Overview

This model features an M12 connection, a 254 mm mounting hole distance, and an approximate 280 mm overall length. The transparent technopolymer body supports easy fluid visibility, while the lens effect helps operators read the oil level even from side positions. For machinery, presses, lubrication units, and hydraulic power packs, this practical visibility reduces the risk of unnoticed low oil levels.

NC Contact Function

The key feature of this version is its normally closed contact. In practical terms, the circuit opens when the minimum oil level or preset temperature threshold is reached. This makes the indicator useful in safety-oriented systems where interruption of the signal can be interpreted as an alert condition. The design also supports a temperature warning function, typically associated with the 80°C threshold used in this product family.

Material and Application Benefits

The HCV.254 series uses a transparent PA-T technopolymer structure suitable for contact with mineral oils and common hydraulic fluids. The construction is engineered for industrial reliability, while ultrasonic welding helps support sealing integrity. Because hydraulic reservoirs operate under changing temperatures and vibration, a compact visual and electrical indicator such as this one can simplify routine inspection and preventive maintenance.

FAQ

What is the Elesa+Ganter 11123-KN used for?

It is used to monitor oil level in hydraulic tanks while also providing an electrical signal when a defined warning condition is reached.

What does NC mean on HCV.254-ST-NC-M12-KN?

NC means normally closed. The contact opens when the minimum level or relevant alarm condition is reached.

Is this product suitable for hydraulic oil tanks?

Yes. It is intended for hydraulic system accessories and is commonly used on reservoirs, power units, and oil tanks.

What is the mounting size?

The product is associated with a 254 mm mounting hole distance and an M12 connection.

Why choose a column level indicator with electrical contact?

It combines direct visual inspection with automated signalling, helping maintenance teams react before low oil level causes operational issues.
