Elesa+Ganter 113501 HCK.127-SST-M12-FKM-GL-P-EHT-NO Electrical Level Indicator
Technical Overview
The Elesa+Ganter 113501 electrical level indicator is a compact HCK.127 series component designed for visual and electrical monitoring of fluid level in hydraulic tanks, lubrication systems, oil reservoirs and industrial machinery. Its model code, HCK.127-SST-M12-FKM-GL-P-EHT-NO, points to a 127 mm hole-centre column level indicator with M12 threaded mounting, stainless steel fixing elements, FKM sealing rings, a borosilicate glass tube and transparent front protection.
This version is especially useful where operators need both direct level visibility and an electrical signal. The NO contact configuration means the level sensor is normally open, making it suitable for systems where a change in level condition must trigger a clear electrical response. The GL tube supports use with oil, water and water/glycol-based solutions, while the FKM O-ring provides a strong sealing choice for higher-temperature environments.
Key Technical Features
The HCK.127 format provides a practical balance between visibility and compact installation. It uses a 127 mm fixing hole centre distance and M12 mounting thread, which makes it familiar for maintenance teams working on hydraulic power units and machine reservoirs. The assembly ends are made from glass-fibre reinforced polyamide-based technopolymer, while the support structure is aluminium. The transparent polycarbonate front protection helps reduce the risk of accidental impact and can be removed for cleaning operations.
The SST configuration identifies AISI 303 stainless steel screws with AISI 304 stainless steel nuts and washers. This is important in machinery areas where corrosion resistance and long-term mechanical reliability matter. The FKM synthetic rubber O-ring supports a maximum continuous working temperature of 130°C when used in compatible oil, water or glycol-based applications.
Application Areas
The Elesa+Ganter 113501 electrical level indicator is commonly considered for hydraulic tanks, lubrication units, industrial oil reservoirs, processing machinery and equipment where fluid level visibility must be supported by a sensor output.

Elesa+Ganter 113501 FAQ
What is the Elesa+Ganter 113501 used for?
It is used to monitor fluid level visually and electrically in tanks, reservoirs and hydraulic systems. The clear column helps operators check the level quickly, while the sensor contact supports automated signalling.
What does NO mean in this model?
NO means normally open. In simple terms, the electrical contact remains open under its normal condition and changes state when the set level condition is reached.
Why is the GL tube important?
The GL designation indicates a borosilicate glass transparent tube. This is relevant for applications involving oil, water or water/glycol-based solutions where chemical and temperature resistance are important.
What does FKM add to the product?
FKM is a high-performance synthetic rubber used for the O-ring. It is selected where sealing reliability and higher temperature resistance are required compared with standard sealing materials.
Is this product suitable for compact machinery?
Yes. With a 127 mm hole-centre distance and M12 mounting, it is suitable for many compact hydraulic and lubrication systems where space, visibility and service access must be balanced.
