Elesa+Ganter 114011 Electrical Oil Level Indicator Technical Guide
Elesa+Ganter 114011 electrical oil level indicator, also known by its full model code HCK.176-ZN-M12-NBR-PC-P-E-NC, is a column-type oil level indicator designed for hydraulic reservoirs where visual level reading and minimum level electrical signalling are required in the same component. The model is especially relevant for hydraulic power units, lubrication systems, industrial tanks and machinery where low oil level monitoring supports safe operation.
Technical Structure of HCK.176-ZN-M12-NBR-PC-P-E-NC
The HCK.176 configuration indicates a 176 mm hole centre distance, giving the operator a clear vertical reading range on the reservoir wall. The ZN section refers to zinc-plated steel screws, nuts and washers, while the M12 connection dimension supports common industrial mounting layouts. NBR sealing rings are used for oil-compatible sealing performance, and the transparent PC tube is intended for oil applications.
The P version includes a transparent polycarbonate front protection plate. This removable front shield helps protect the visible tube from dirt, accidental contact and routine maintenance impact. For equipment operating in dusty workshops, mobile hydraulic units or compact machine frames, this detail can make level inspection easier over time.
Elesa+Ganter 114011 Normally Closed Minimum Level Sensor
The E-NC part of the code defines an electrical minimum level sensor with a normally closed contact. In practice, the contact opens when the float reaches the minimum level threshold. This makes the indicator useful in control systems where the circuit must react when the oil level drops below a defined safety point.
The float is based on polypropylene technopolymer and is suitable for a maximum continuous working temperature of 80°C. The magnetic float activates the reed contact near the minimum threshold, while the white contrast screen behind the tube improves readability during daily checks.
Where This Product Type Is Used
The Elesa+Ganter 114011 HCK.176-ZN-M12-NBR-PC-P-E-NC electrical oil level indicator is commonly selected for hydraulic tanks that need both local visual control and a simple electrical signal for minimum oil level. It is suitable for mineral oil systems, machine tools, hydraulic presses, compact power packs and industrial automation equipment.

Elesa+Ganter 114011 FAQ
What product type is Elesa+Ganter 114011?
It is an electrical oil level indicator with a column-style visual tube and a minimum level sensor. Its product type is best described as an electrical column oil level indicator for hydraulic systems.
What does the NC contact mean?
NC means normally closed. In this configuration, the electrical contact opens when the oil level reaches the minimum level. This behaviour is useful when the control system is designed to detect an interruption as a low-level warning.
Is the PC tube suitable for water?
The PC version is intended for oil applications. For water or water-glycol mixtures, a glass tube version is usually more appropriate, depending on the exact system conditions.
Why is the 176 mm centre distance important?
The 176 mm centre distance defines the mounting distance between the fixing holes. It must match the tank design or the existing replacement indicator dimensions.
Can this model be installed near magnetic fields?
It should not be installed close to magnetic fields, because the sensor uses a magnetic float and reed contact principle. Magnetic interference may affect reliable switching behaviour.
