Elesa+Ganter 113657 HCK.127-SST316-M12-NBR-GL-P-E-SW Oil Level Indicator

The Elesa+Ganter 113657 HCK.127-SST316-M12-NBR-GL-P-E-SW oil level indicator is an electrical column level indicator for applications that require both direct visual fluid monitoring and electrical switching capability. It is part of the HCK.127 group, meaning it is built around a 127 mm centre distance and M12 mounting geometry.

Technical Configuration

This version includes AISI 316 stainless steel fixing parts, NBR sealing rings, a GL borosilicate glass level tube and a transparent polycarbonate front guard. The AISI 316 stainless hardware supports installations where corrosion resistance is a priority, especially in humid production areas, outdoor-adjacent machinery or equipment exposed to cleaning processes.

E-SW Changeover Contact

The E-SW designation refers to an electrical changeover contact. Unlike a simple normally open or normally closed configuration, a changeover contact can provide more flexible signal logic for machine builders and maintenance teams. This is useful when the same level condition needs to be interpreted differently by a control circuit, alarm output or monitoring relay.

Why It Matters in Maintenance

Fluid level is one of the most basic yet critical indicators of machine health. A low level may suggest leakage, consumption, incorrect filling or a maintenance interval that has been missed. By combining a clear visual column with an electrical switching function, this indicator supports both manual inspection and automated monitoring.

Elesa+Ganter 113657 FAQ

What is the product type of Elesa+Ganter 113657?

It is an electrical oil level indicator with visual column reading and changeover contact capability.

What does E-SW mean?

E-SW indicates an electrical switching configuration with changeover contact logic, offering flexible signal integration.

Why choose SST316 hardware?

SST316 hardware offers strong corrosion resistance and is suitable for more demanding industrial environments than standard plated fixing parts.

Does this indicator support visual inspection?

Yes. The transparent GL tube allows operators to read the level directly from outside the tank.

Where is it commonly installed?

It is commonly used on hydraulic tanks, lubrication systems, oil reservoirs and industrial machinery where level visibility and electrical monitoring are both needed.
