Elesa+Ganter 113739-NP HCK.127 Oil Level Indicator

Overview of Elesa+Ganter 113739-NP

The Elesa+Ganter 113739-NP oil level indicator is a column-style fluid level indicator for industrial oil reservoirs. Its full reference, HCK.127-SST316-M12-FKM-PC-NP-STL, shows that it belongs to the HCK.127 family and includes AISI 316 stainless steel fixing elements, M12 thread, FKM sealing rings, a polycarbonate level tube, no front protection, and an STL temperature probe configuration.

This model is designed for applications where corrosion resistance, oil visibility, and temperature monitoring are important. The NP version is supplied without transparent front protection, which may be preferred in installations where the indicator is already protected by machine layout or enclosure design.

Material and Design Details

The HCK.127 body format uses reinforced technopolymer assembly ends, aluminium support, and a graduated contrast screen. This structure provides a practical balance between readability, durability, and compact installation.

The SST316 configuration means the screws, nuts, and washers are made from AISI 316 stainless steel. This is valuable in humid, washdown, marine-adjacent, or chemically demanding environments where stronger corrosion resistance is required.

Technical Performance

The 127 mm hole centre distance makes this indicator suitable for smaller and medium reservoir designs. M12 fixing supports secure installation, while FKM O-rings are used where elevated temperature resistance and oil compatibility are important.

The transparent polycarbonate tube is intended for oil-level inspection. Since this version has no front protection, users should check that the installation location is not exposed to direct impact, abrasion, or frequent contact with tools during maintenance.

Temperature Monitoring

The STL suffix refers to a PT100 temperature electrical probe. This allows the machine control or monitoring system to read fluid temperature through resistance variation. For accurate readings, wiring should be kept away from electrical noise sources, motors, and switchgear where possible.

Elesa+Ganter 113739-NP FAQ

What product type is Elesa+Ganter 113739-NP?

It is an HCK.127 oil level indicator with AISI 316 stainless steel fixing parts and PT100 temperature probe configuration.

What does NP mean in this model?

NP means the indicator is supplied without transparent front protection.

Why choose AISI 316 stainless steel?

AISI 316 is selected for stronger corrosion resistance, especially in humid or chemically challenging industrial environments.

Is the PC tube suitable for water-glycol fluids?

The PC tube version is intended for oil. For water or water-glycol solutions, glass tube variants are usually considered.

Does this model measure temperature?

Yes. The STL configuration indicates a PT100 temperature electrical probe for temperature monitoring.
