Elesa+Ganter 113211-KN HCK.127-ZN-M12-FKM-GL-P-EHT-NC-80-NC-KN Electrical Oil Level Indicator

The Elesa+Ganter 113211-KN electrical oil level indicator is a column-type level and temperature monitoring device for industrial fluid reservoirs. Its complete stock name, HCK.127-ZN-M12-FKM-GL-P-EHT-NC-80-NC-KN, identifies a 127 mm HCK.127 indicator with M12 connection, FKM sealing, glycol-compatible GL construction and normally closed electrical contacts.

Built for Reliable Reservoir Monitoring

Hydraulic and lubrication systems depend on stable fluid levels. When the level drops too low, pumps can draw air, pressure can become unstable and components may wear faster. This indicator gives maintenance teams two layers of information: direct visual level reading and electrical status signalling. The NC contact logic supports control strategies where a closed circuit represents normal status and a changed signal indicates a limit condition.

Level and Temperature Control in One Unit

The EHT configuration combines minimum level monitoring with temperature threshold control. In this version, both the level contact and the 80°C temperature contact are normally closed. This makes the component suitable for control cabinets, alarm relays and PLC inputs that are designed around NC monitoring logic. The result is a cleaner installation compared with using separate visual gauges and independent temperature switches.

Materials and Installation Context

The HCK.127 body format offers a 127 mm fixing centre distance, while the M12 connection supports practical industrial wiring. The Pyrex tube provides fluid visibility and compatibility for glycol-based solutions. FKM sealing contributes to resistance in applications where temperature and fluid chemistry are important. For replacement or procurement, the exact phrase Elesa+Ganter 113211-KN electrical oil level indicator helps ensure the correct NC variant is selected.

Elesa+Ganter 113211-KN FAQ

What is the purpose of the KN version?

The KN suffix identifies a specific catalogue configuration. It should be kept in the product name when ordering or comparing technical documents.

What does the 80°C contact do?

It provides an electrical status change when the monitored fluid temperature reaches the configured threshold of approximately 80°C.

Is this model suitable for automated alarms?

Yes. Its electrical contacts can be connected to suitable control circuits, alarm relays or PLC inputs.

Why is the NC version chosen?

NC contact logic is often used where the system should monitor continuity during normal operation and react when the circuit changes state.

Can this indicator replace a simple sight glass?

In many systems, yes. It provides visual indication like a sight glass, but also adds electrical monitoring for level and temperature conditions.
