Elesa+Ganter 113647 HCK.127-SST316-M12-NBR-GL-P-80-NC Oil Level Indicator
The Elesa+Ganter 113647 oil level indicator is a HCK.127 column indicator developed for visual fluid level monitoring with an integrated normally closed temperature contact rated at 80°C. It is suitable for hydraulic reservoirs where both direct level visibility and a simple electrical signal are useful for preventive maintenance.
Key Technical Characteristics
The HCK.127 format uses a 127 mm hole centre distance and M12 threaded assembly. This execution includes AISI 316 stainless steel screws, nuts and washers, NBR O-rings, a borosilicate glass transparent tube and removable polycarbonate front protection. The GL tube is appropriate for oil, water and water-glycol based solutions up to 50%, while NBR sealing is commonly used in oil-based hydraulic systems up to 100°C continuous temperature.
Normally Closed 80°C Sensor Function
The “80-NC” configuration means the unit includes a temperature sensor with a normally closed contact logic. In practical terms, this can support machine monitoring circuits where a defined temperature condition must be detected. The result is a more informative tank interface: operators can see the fluid level, while the control system can receive a temperature-related signal.
Where It Fits Best
This indicator is relevant for hydraulic power packs, compact industrial machines, lubrication systems, mobile equipment reservoirs and process skids. Its stainless fixing parts help in demanding environments, while the glass tube supports clearer resistance for mixed fluid applications compared with basic plastic-only viewing windows.

Elesa+Ganter 113647 FAQ
What does NC mean on this oil level indicator?
NC means normally closed. The contact logic is selected for control circuits that require a closed state under normal conditions.
Is Elesa+Ganter 113647 only for oil?
No. The GL version may be used with oil, water and water-glycol based solutions up to 50%, depending on actual pressure, temperature and chemical compatibility.
What makes this different from a basic visual indicator?
It combines visual level reading with an 80°C normally closed sensor, adding an electrical monitoring layer.
Is the front protection removable?
Yes. The transparent polycarbonate front protection can be removed for cleaning operations.
