Elesa+Ganter 113457 Electrical Oil Level Indicator

The Elesa+Ganter 113457 electrical oil level indicator is a stainless steel HCK.127 model developed for hydraulic reservoirs that require reliable level visibility and electrical monitoring. Its full code, HCK.127-SST-M12-FKM-PC-P-E-NC-STL, identifies a 127 mm hole-centre column level indicator with M12 connection, FKM sealing rings, polycarbonate level tube, removable front protection, normally closed minimum-level contact and PT100 temperature probe.

Technical Overview

This model is part of the HCK-E-STL range, which is used when a simple visual gauge is not enough. The indicator allows operators to see the oil level directly, while the integrated electrical sensor supports automated minimum-level detection. The NC contact is normally closed during standard operating conditions and opens when the minimum level threshold is reached. This contact logic is often preferred in monitoring circuits where a broken wire or loss of continuity may also be treated as a fault condition.

The SST construction uses stainless steel fixing hardware, including AISI 303 screws and AISI 304 nuts and washers. This helps the indicator maintain mechanical reliability in demanding machine environments. The transparent polycarbonate tube is suitable for oil service, and the front protection can be removed for cleaning. FKM O-rings support higher continuous working temperatures than many standard elastomer seals, making this configuration a strong choice for hydraulic systems where oil temperature can rise during long duty cycles.

Practical Use in Hydraulic Systems

The Elesa+Ganter 113457 is relevant for hydraulic tank level monitoring, lubrication reservoirs, industrial machinery, presses, power units and equipment where level loss can lead to pump damage or unstable operation. The PT100 probe adds temperature information, helping maintenance teams track oil condition and thermal behaviour during operation.

Elesa+Ganter 113457 Frequently Asked Questions

What is the Elesa+Ganter 113457 used for?

It is used to monitor oil level in hydraulic tanks and similar reservoirs. It combines a visible level window with an electrical minimum-level sensor and PT100 temperature probe.

What does NC mean on this model?

NC means normally closed. The contact opens when the minimum level is reached, allowing the control system to detect a low-level condition.

Why choose FKM seals?

FKM seals are selected when better temperature and chemical resistance is needed compared with standard NBR seals. This can be important in hydraulic oil systems running under demanding conditions.

Is this model suitable for water-glycol mixtures?

The PC version is intended for oil applications. For water or water-glycol solutions, a GL borosilicate glass version is generally the more appropriate configuration.
