Elesa+Ganter 113757 HCK.127-SST316-M12-FKM-PC-P-E-NC-STL Electrical Oil Level Indicator

The Elesa+Ganter 113757 HCK.127-SST316-M12-FKM-PC-P-E-NC-STL electrical oil level indicator is designed for reliable visual and electrical monitoring of fluid level in hydraulic reservoirs, lubrication systems, machine tools, industrial tanks and compact power units. It belongs to the HCK.127 family, which means it uses a 127 mm hole centre distance and an M12 mounting configuration.

Technical Overview

This model combines a transparent polycarbonate level tube, removable polycarbonate front protection and FKM sealing rings. The SST316 reference indicates AISI 316 stainless steel screws, nuts and washers, making the unit suitable for demanding environments where corrosion resistance is important. The NC electrical contact configuration means the circuit logic is normally closed and changes state when the minimum level threshold is reached.

Where This Indicator Is Used

The product is commonly used in hydraulic oil reservoirs, industrial lubrication circuits and machinery where operators need both quick visual inspection and a signal for a control panel, relay or PLC. The contrast screen behind the column improves readability, while the electrical sensor supports preventive maintenance by helping detect abnormal oil level conditions before they cause downtime.

Key Technical Points

The HCK.127 format provides a compact but readable level window. The FKM seal is suitable for higher temperature resistance compared with standard NBR alternatives. The PC tube is intended for oil applications, and the front protection can be removed for cleaning.

Elesa+Ganter 113757  FAQ

What does NC mean on this oil level indicator?

NC means normally closed. In practical terms, the electrical contact is closed during normal conditions and changes when the minimum level point is reached.

Is the Elesa+Ganter 113757 suitable for hydraulic oil?

Yes, it is intended for oil level monitoring in hydraulic and lubrication systems, provided the operating fluid, temperature and pressure remain within the product limits.

Why is AISI 316 stainless steel important?

AISI 316 stainless steel offers improved resistance in humid, industrial or mildly corrosive environments. This is useful when the reservoir is exposed to washdown areas, outdoor conditions or aggressive atmospheres.

What is the benefit of FKM sealing?

FKM sealing provides stronger thermal and chemical resistance than many standard elastomers, making it a good choice for higher-duty oil monitoring applications.
