Elesa+Ganter 113159 HCK.127-ZN-M12-FKM-PC-P-EHT-NC Electrical Level Indicator

The Elesa+Ganter 113159 HCK.127-ZN-M12-FKM-PC-P-EHT-NC electrical level indicator is built for hydraulic systems and industrial machine reservoirs where accurate oil level visibility and electrical level feedback are required. It gives operators a clear visual reference while also supporting signal-based monitoring through a normally closed contact configuration.

Construction and Materials

This HCK.127 indicator is configured with a 127 mm hole centre distance and M12 mounting. The ZN version uses zinc-plated steel screws, nuts and washers. The transparent PC tube is intended for oil service and helps make the fluid level easy to read from the front and side viewing positions.

The indicator also includes FKM sealing rings. This is an important material choice for systems where temperature resistance and oil compatibility matter. The technopolymer assembly ends, aluminium support and white graduated contrast screen contribute to durability, readability and stable installation.

EHT-NC Electrical Behaviour

The EHT-NC configuration indicates a normally closed electrical contact. In practical terms, the circuit is closed in its default state and changes condition when the float reaches the switching threshold. The float contains a magnetic element that interacts with the contact system, helping the machine detect low-level or monitored level conditions.

Application Areas

The Elesa+Ganter 113159 HCK.127-ZN-M12-FKM-PC-P-EHT-NC electrical level indicator is suitable for hydraulic power units, oil tanks, lubrication reservoirs, production machinery and industrial automation systems. It is especially useful where teams want a simple, readable and electrically integrated level monitoring component.

Frequently Asked Questions

What is Elesa+Ganter 113159 used for?

It is used for visual and electrical oil level monitoring in hydraulic tanks and industrial machine reservoirs.

What does NC mean in this code?

NC means normally closed. It describes the default electrical contact state before the monitored switching condition occurs.

Why is the HCK.127 size important?

The 127 value identifies the mounting centre distance, which is essential when matching the indicator to an existing tank design.

Is this product suitable for mineral oil systems?

Yes. The PC tube version is intended for oil applications, including many mineral oil based hydraulic systems.

Why would an engineer choose this instead of a basic sight glass?

Unlike a simple visual-only indicator, this model combines direct level visibility with an electrical contact, making it more useful for monitored machinery.
