Elesa+Ganter 113047 HCK.127-ZN-M12-NBR-GL-P-80-NO Electrical Level Indicator

The Elesa+Ganter 113047 electrical level indicator is designed for hydraulic tanks, lubrication systems and industrial fluid reservoirs where visual monitoring and temperature-related switching are both required. Known by its full model name, HCK.127-ZN-M12-NBR-GL-P-80-NO, this component combines a column-style oil level indicator with a normally open 80°C temperature electrical sensor.

Technical Overview

This indicator uses a 127 mm hole centre distance with M12 threaded fixing. The ZN execution refers to zinc-plated steel screws, nuts and washers, while the NBR sealing rings support applications with a maximum continuous working temperature of 100°C. Its GL transparent tube is made from borosilicate glass, making it suitable for oil, water and water/glycol-based solutions up to 50%. The P execution adds removable polycarbonate front protection, helping keep the visible column safer and easier to clean.

Where It Is Used

For maintenance teams, the main value of the Elesa+Ganter 113047 HCK.127-ZN-M12-NBR-GL-P-80-NO electrical level indicator is fast condition awareness. Operators can check fluid level from outside the tank without opening the system. The integrated 80-NO sensor adds a signal point when the temperature threshold is reached, supporting safer monitoring in compact hydraulic equipment, machine tools and power units.

Design Benefits

The black glass-fibre reinforced technopolymer ends, aluminium support and white contrast screen create clear level visibility. The borosilicate glass tube is a practical choice where compatibility with water/glycol mixtures matters. Because the sensor contact is normally open, it is commonly used in circuits where a temperature event closes the contact and triggers a control response.
