Elesa+Ganter 113187-KN HCK.127-ZN-M12-FKM-GL-P-E-SW-KN Oil Level Indicator

Technical Overview

The Eseşa+Ganter 113187-KN oil level indicator, listed as HCK.127-ZN-M12-FKM-GL-P-E-SW-KN, is designed for visual fluid level monitoring in hydraulic tanks, lubrication units, industrial reservoirs and machine assemblies where reliable inspection is important. This model belongs to the HCK.127 range and uses a 127 mm hole centre distance, making it suitable for compact and medium-sized equipment layouts.

The product code defines its construction clearly: ZN indicates zinc-plated steel fixing components, M12 refers to the mounting thread, FKM identifies the sealing material, and GL specifies a transparent borosilicate glass tube. The P execution includes front protection, while the E-SW version includes a change-over electrical level contact. The KN suffix refers to the knob-style fastening execution.

Material and Application Benefits

The FKM sealing ring supports higher thermal resistance than standard NBR seals, which makes this model suitable for demanding oil and water/glycol-based applications. The borosilicate glass tube provides strong transparency and chemical compatibility for industrial fluid monitoring. For engineers searching for an Elesa+Ganter 113187-KN HCK.127-ZN-M12-FKM-GL-P-E-SW-KN oil level indicator, this configuration offers both visual inspection and electrical signalling in one component.

Electrical Contact Function

The SW contact is a change-over contact. This means the electrical signal can switch between two terminals when the minimum fluid level threshold is reached. In practical terms, the component can support alarm, stop, warning or control logic depending on the machine design. It is especially useful where maintenance teams need both a visible level reference and a signal for automated monitoring.

Recommended Use

This indicator is appropriate for hydraulic power units, industrial tanks, mobile machinery, lubrication systems and equipment where oil level visibility must remain clear from the outside. For related Elesa+Ganter components, see Elesa+Ganter technical products.

FAQ

What is Elesa+Ganter 113187-KN used for?

It is used to monitor the fluid level in tanks and hydraulic reservoirs while also providing an electrical change-over contact for minimum level detection.

What does GL mean in this product code?

GL means the indicator has a transparent borosilicate glass tube, suitable for oil, water and water/glycol-based solutions within the correct operating conditions.

Why is FKM important?

FKM sealing provides better resistance to higher temperatures and certain fluids than standard rubber seals, making it useful in more demanding industrial environments.

What does SW contact mean?

SW means change-over electrical contact. It switches between terminals when the defined level condition is reached, allowing flexible machine control integration.
