Elesa+Ganter 111283 Rapid Level with Float: Technical Overview of HFL-EF-NC

The Elesa+Ganter 111283 rapid level with float, also known as HFL-EF-NC, is designed for reliable oil level monitoring in hydraulic tanks, lubrication systems, and industrial fluid reservoirs. It helps operators detect a predefined liquid level through a float-based mechanism and an electrical contact. This makes it useful in machinery where early level detection supports operational safety and preventive maintenance.

What Is the HFL-EF-NC Used For?

This rapid level indicator is commonly used when a tank or reservoir requires a clear electrical signal once the fluid reaches a specific minimum or maximum level. The HFL-E range is valued for its adjustable dipstick design. The float and dipstick can be disassembled and cut to the required length, allowing technicians to define the most suitable switching point for the application.

Key Technical Features

The HFL-EF-NC version is part of the Elesa+Ganter HFL-E series. It uses a technopolymer body and a float level sensor configuration. The “NC” designation indicates a normally closed electrical contact. This means the contact state is selected for systems where continuity is required until the liquid reaches the switching point. The 111283 version is identified as HFL-EF-NC and is associated with a 500 mm length and approximately 135 g weight.

Why Engineers Choose It

In hydraulic systems, oil level monitoring is not only a maintenance task; it is part of machine protection. A low oil level may increase heat, cavitation risk, and component wear. A rapid float level indicator provides a direct and practical way to monitor the fluid condition before damage occurs.

The Elesa+Ganter 111283 rapid level with float is especially suitable for compact systems where a simple, durable, and adjustable level signal is required. For more information about Elesa+Ganter components, technical compatibility should always be checked according to the fluid type, operating temperature, and installation position.

Elesa+Ganter 111283 FAQ

What does HFL-EF-NC mean?

HFL-EF-NC refers to a rapid level indicator with float from the HFL-E series. The NC marking means the electrical contact is normally closed.
