Elesa+Ganter 11128 HCV.254-E-STL-NC-M12 Oil Electrical Level Indicator

The Elesa+Ganter 11128 HCV.254-E-STL-NC-M12 oil electrical level indicator is a column-type indicator designed for oil level visibility, minimum level electrical signalling, and temperature monitoring. It is commonly used in hydraulic systems, lubrication units, machine reservoirs, and industrial equipment where oil level control is part of operational safety.

Technical Profile

This product belongs to the HCV-E-STL series and uses a transparent polyamide-based PA-T technopolymer body. The material is selected for resistance to shocks, oils with additives, solvents, and industrial fluid environments. The HCV.254 model has a 254 mm fixing distance and an overall length of 280 mm. It is supplied in the NC version, meaning the contact is normally closed and opens when the minimum level is reached.

Integrated Level and Temperature Monitoring

The Elesa+Ganter 11128 HCV.254-E-STL-NC-M12 oil electrical level indicator combines visual level reading with an electrical minimum level signal. The built-in temperature probe uses a platinum resistor, allowing the system to generate an analog electrical signal related to oil temperature. This helps maintenance teams detect abnormal operating conditions before they become costly failures.

Visibility and Sealing

The transparent column body supports quick visual inspection, while the lens effect improves fluid visibility from side positions. The unit is manufactured with ultrasound welding to help ensure sealing performance. The swivelling connector with built-in cable gland allows front or axial output and provides IP65 protection against water sprays when correctly installed.

Industrial Use Cases

This indicator is particularly useful in hydraulic reservoirs, oil tanks, gear units, and machinery where the operator needs both a visual reference and electrical feedback. The NC contact logic is often preferred in safety-related circuits because a change in signal can indicate that the oil has reached the minimum threshold.

Elesa+Ganter 11128 FAQ

What does NC mean in this product code?

NC means normally closed. In this model, the electrical contact opens when the oil reaches the minimum level threshold.

Does the indicator only show oil level visually?

No. It provides visual level checking, an electrical minimum level signal, and an analog temperature signal through the integrated probe.

What is the maximum working temperature?

The maximum continuous working temperature is 90°C when used with oil under suitable operating conditions.

What protection class does the connector provide?

The connector provides IP65 protection against water sprays when installed correctly.

Why is the HCV.254 size important?

The HCV.254 size indicates a 254 mm fixing distance, making it suitable for larger reservoir level monitoring compared with shorter versions in the same series.
