Elesa+Ganter 111171 HCY.254-E-ST-NO-M12 Oil Electrical Level Indicator

Technical Introduction

The ELESA+GANTER 111171 HCY.254-E-ST-NO-M12 oil electrical level indicator is a larger HCY-E-ST series model designed for hydraulic tanks that require extended visual level monitoring. With its 254 mm mounting centre distance, it is suitable for reservoirs where a wider level range must be observed clearly.

This version includes a MIN level electrical sensor and a temperature electrical probe. The NO contact configuration means the electrical contact is normally open and closes when the minimum oil level is reached. This supports automatic signalling, operator alerts, and maintenance planning in hydraulic systems.

Materials and Technical Features

The indicator body is made from transparent polyamide-based technopolymer, offering direct visual access to the oil level. It includes nickel-plated brass screws, NBR synthetic rubber sealing rings, a technopolymer float, and a watertight sensor block. The white lacquered aluminium contrast screen improves readability and can be marked before installation.

The maximum continuous working temperature is 80°C with oil. In laboratory testing with CB68 mineral oil at 23°C, the HCY.254 weld stood up to 8 bar for a limited period. This technical value should be considered alongside the real operating conditions of the machine, including temperature, fluid type, vibration, and tank pressure.

Best-Fit Applications

The 254 mm format is especially useful for larger hydraulic reservoirs, oil tanks, heavy machinery, production lines, and power units where extended level visibility is needed. By combining visual inspection with electrical monitoring, it helps maintenance teams respond before low oil levels affect system performance.

Elesa+Ganter 111171 HCY.254-E-ST-NO-M12 Indicator FAQ

What is the main benefit of Elesa+Ganter 111171 HCY.254-E-ST-NO-M12?

It provides extended visual oil level monitoring and an electrical warning function for minimum level detection.

What does the 254 value mean?

It refers to the 254 mm mounting centre distance, making this model suitable for larger reservoirs.

Does this model include temperature monitoring?

Yes, it includes a temperature electrical probe as part of the HCY-E-ST series design.

What happens when the minimum level is reached?

Because this is an NO version, the electrical contact closes when the minimum level is reached.

Is this product suitable for every oil system?

It is designed for oil level monitoring, but compatibility should always be checked against the actual oil type, pressure, temperature, and installation conditions.
