Elesa+Ganter 113503 HCK.127-SST-M12-FKM-GL-P-EHT-NC Electrical Level Indicator
Technical Overview
The Elesa+Ganter 113503 electrical level indicator is an HCK.127 series column level indicator developed for visual and electrical fluid monitoring. Its model code, HCK.127-SST-M12-FKM-GL-P-EHT-NC, identifies a 127 mm hole-centre product with M12 mounting, stainless steel fixing hardware, FKM O-ring sealing, a borosilicate glass level tube, transparent protection and a normally closed electrical contact.
The NC contact makes this version useful in monitoring strategies where the circuit is closed in the normal state and changes when the fluid reaches the defined switching condition. This configuration is often preferred in systems where interruption of the signal should be easy to detect.
Technical Design
The HCK.127 body uses black glass-fibre reinforced polyamide-based technopolymer assembly ends and an aluminium support. Its graduated contrast screen improves readability and helps operators check the fluid level from the machine side without unnecessary downtime. The borosilicate glass tube is designed for oil, water and water/glycol-based solutions, making the product suitable for a broad range of industrial fluid systems.
The SST hardware configuration includes AISI 303 stainless steel screws and AISI 304 stainless steel nuts and washers. This supports durability in demanding equipment environments. The FKM sealing ring is a practical advantage in higher-temperature applications, especially where standard rubber sealing may not be the best long-term option.
Practical Application
The Elesa+Ganter 113503 electrical level indicator is suitable for hydraulic reservoirs, lubrication units, oil tanks, industrial gear systems, cooling-support circuits and machine service panels. It gives maintenance teams a direct visual reference while enabling the control system to receive a normally closed signal.

FAQ
What is the main purpose of the Elesa+Ganter 113503?
Its purpose is to provide both visual fluid level indication and electrical level monitoring in industrial systems such as hydraulic tanks and lubrication reservoirs.
What does NC mean?
NC means normally closed. The electrical contact is closed in its normal condition and changes state when the monitored level condition is reached.
Why would an engineer choose NC instead of NO?
An NC contact is often preferred when a machine control system is designed to notice a broken or changed circuit more directly. The correct choice depends on the safety logic and control architecture.
Does the product include front protection?
Yes. The P designation indicates transparent polycarbonate front protection. It helps protect the level tube and can be removed for cleaning operations.
Is the Elesa+Ganter 113503 suitable for higher temperatures?
The FKM sealing system is intended for higher-temperature use than standard NBR sealing. Application suitability should still be checked against the actual fluid, pressure and temperature conditions.
