Elesa+Ganter 113791 Electrical Oil Level Indicator
Elesa+Ganter 113791 electrical oil level indicator, listed as HCK.127-SST316-M12-FKM-GL-P-E-NO-80-NO, is designed for visual oil level checking and electrical monitoring in hydraulic and lubrication systems. It combines a 127 mm column indicator layout with stainless steel fixing parts, FKM seals, borosilicate glass tube construction, a float-based level signal, and an 80°C temperature switching function.
Technical Structure and Material Selection
This model has a 127 mm hole-centre distance and M12 mounting. The SST316 configuration indicates AISI 316 stainless steel fixing parts, a preferred choice in humid, washdown, or corrosion-sensitive machine environments. The FKM sealing system supports reliable sealing where temperature, oil additives, or chemical exposure may be more demanding than standard applications.
The GL designation refers to a transparent borosilicate glass tube. Borosilicate glass is valued in level indicators because it offers clear visibility and stable performance when exposed to heat and industrial fluids. The P version uses a polyamide-based technopolymer float, allowing the level sensor system to detect fluid level changes and communicate them electrically.
Normally Open Level and Temperature Monitoring
The E-NO-80-NO configuration means the unit is equipped with electrical monitoring features using normally open contact logic. In practice, a normally open signal is often preferred when the control circuit is designed to close only when the monitored condition reaches the defined switching point. The 80°C temperature setting helps machine builders and maintenance teams detect overheating risks before they lead to oil degradation, seal damage, or reduced hydraulic efficiency.
The Elesa+Ganter 113791 HCK.127-SST316-M12-FKM-GL-P-E-NO-80-NO oil level indicator is therefore not only a sight level indicator. It also supports preventive maintenance by allowing the machine control system to react to level and temperature conditions.
Typical Applications
This product is suitable for hydraulic reservoirs, lubrication units, industrial automation machines, machine tools, compact power packs, and process equipment where operators need both visual confirmation and electrical status feedback.

Elesa+Ganter 113791 FAQ
What is Elesa+Ganter 113791 used for?
It is used to monitor oil level visually and electrically in hydraulic and lubrication systems. It can also provide a temperature switching signal at 80°C.
What does SST316 mean in this model?
SST316 indicates stainless steel fixing parts made from AISI 316, which provides improved corrosion resistance compared with many standard steels.
What does GL mean?
GL indicates a transparent borosilicate glass tube, selected for clear visibility and stable performance in industrial fluid monitoring.
What does NO mean?
NO means normally open. The electrical contact remains open under normal conditions and closes when the defined switching condition is reached.
Why is the 80°C contact useful?
The 80°C temperature contact helps detect excessive oil temperature, supporting safer operation and planned maintenance before overheating becomes a larger problem.
