Elesa+Ganter 113493 HCK.127-SST-M12-FKM-GL-P-E-NC-80-NC Electrical Level Indicator

The Elesa+Ganter 113493 electrical level indicator is intended for fluid systems where visual level reading and normally closed electrical monitoring are required together. Its full code, HCK.127-SST-M12-FKM-GL-P-E-NC-80-NC, identifies a 127 mm HCK column level indicator with stainless steel fixing components, M12 connection, FKM sealing, borosilicate glass level tube, transparent front protection, NC level contact and NC 80°C temperature sensor function.

Technical Description

The 127 mm mounting hole-centre distance makes this model suitable for a broad range of hydraulic reservoirs and oil tanks. SST hardware provides stainless steel fixing reliability, while the FKM O-ring is selected for higher temperature resistance. The GL borosilicate glass tube supports clear visual reading and is suitable for oil, water and water/glycol-based solutions within specified use conditions.

The NC contact logic is the key difference in this version. In a normally closed level sensor, the contact opens when the minimum level condition is reached. This behaviour is often preferred in systems where wire break detection, fail-safe logic or continuous circuit supervision is important. The 80-NC temperature sensor function follows the same normally closed concept at the temperature threshold.

Why NC Monitoring Is Useful

The Elesa+Ganter 113493 HCK.127-SST-M12-FKM-GL-P-E-NC-80-NC electrical level indicator is particularly relevant for machinery where a lost signal should be treated as a warning condition. In many industrial control strategies, normally closed circuits are preferred because interruption of the circuit can indicate either a real process condition or a wiring fault that needs attention.

Application Areas

This product type is used in hydraulic power units, industrial machines, lubrication reservoirs, automation equipment and fluid-control systems. The combination of glass visibility, front protection, FKM sealing and electrical monitoring makes it a robust choice for technical teams that need more than a simple sight glass.

Elesa+Ganter 113493 FAQ

What type of product is Elesa+Ganter 113493?

It is an electrical column level indicator with visual level reading, normally closed level contact and normally closed 80°C temperature sensor function.

What does NC mean?

NC means normally closed. The contact is closed during normal condition and opens when the set condition is reached.

When should an NC version be preferred?

NC versions are often preferred when the control system must detect circuit interruption, minimum level conditions or possible wiring faults.

What does GL-P mean?

GL refers to the borosilicate glass tube, while P refers to transparent front protection for additional mechanical shielding.

Is FKM necessary for every system?

Not always. FKM is especially useful where higher temperature or stronger chemical resistance is needed compared with standard sealing materials.
