Elesa+Ganter 114047 HCK.176 GL-P-80-NO Oil Level Indicator
Elesa+Ganter 114047 oil level indicator is a HCK.176 column-type indicator used for visual fluid level control and temperature signal monitoring in hydraulic and industrial reservoir systems. The product code HCK.176-ZN-M12-NBR-GL-P-80-NO describes a 176 mm hole-centre level indicator with M12 mounting, zinc-plated steel connection parts, NBR seals, borosilicate glass tube, transparent front protection and an 80°C normally open temperature contact.
Technical Meaning of the Product Code
HCK.176 defines the product family and mounting centre distance. ZN points to zinc-plated steel fixing hardware, while M12 identifies the mounting thread format. NBR refers to the sealing material, commonly used for oil-based industrial systems. GL means the visual tube is borosilicate glass, and P indicates the protected front structure.
80°C NO Contact Logic
The 80-NO configuration is an important difference in this model. Normally open contact logic means the circuit remains open during normal conditions and changes state when the set temperature condition is reached. This arrangement is often selected for alarm circuits, machine protection signals or warning lamps where activation is required only after temperature rises to the threshold.

Industrial Use Cases
The Elesa+Ganter 114047 HCK.176 oil level indicator is suitable for hydraulic units, lubrication reservoirs, industrial presses, machine tools and automation systems. It gives maintenance personnel a quick visual reference while allowing the control system to receive a temperature-related signal.
Why This Indicator Supports Maintenance Planning
Oil condition and temperature are closely connected to machine reliability. When fluid level is too low, pumps may draw air, seals may wear faster and heat can increase. A protected glass level indicator with temperature contact supports preventive maintenance by making abnormal conditions easier to detect before they become costly failures.
Elesa+Ganter 114047 FAQ
What product type is Elesa+Ganter 114047?
It is a HCK.176 GL oil level indicator with transparent front protection and 80°C normally open temperature contact.
What does NO mean in the product code?
NO means normally open. The contact is open during normal operation and changes state when the temperature threshold is reached.
How is 114047 different from 114045?
Both are HCK.176 GL-P models with 80°C temperature monitoring, but 114047 uses NO contact logic while 114045 uses NC contact logic.
Is this model suitable for hydraulic systems?
Yes. It is designed for industrial fluid level indication and is commonly used on hydraulic oil tanks and machinery reservoirs.
Why does the GL tube matter?
The borosilicate glass tube improves visual clarity and supports reliable level reading in industrial environments where durability and chemical resistance are important.
