Elesa+Ganter 113045 HCK.127 GL Level Indicator with 80°C NC Temperature Sensor

Elesa+Ganter 113045 HCK.127 GL level indicator, supplied as HCK.127-ZN-M12-NBR-GL-P-80-NC, is a column level indicator designed for fluid visibility and temperature-limit signalling. Unlike PC tube versions intended primarily for oil, the GL configuration uses a borosilicate glass transparent tube suitable for oil, water, and water/glycol-based solutions up to 50%, depending on working conditions.

Material and Configuration Details

The 127 designation refers to the 127 mm hole centre distance. ZN indicates zinc-plated steel screws, nuts, and washers. M12 identifies the screw thread, while NBR describes the synthetic rubber sealing rings. The GL tube is paired with a removable polycarbonate front protection, giving the indicator improved suitability for environments where accidental contact with the level column may occur.

80°C NC Temperature Sensor

The 80-NC suffix identifies a maximum temperature electrical sensor set at 80°C with normally closed contact behaviour. In this configuration, the contact opens when the preset temperature is reached. This is valuable in hydraulic and process-related equipment where temperature must be supervised before the fluid condition affects system reliability, component life, or safe operation.

Use in Oil, Water and Glycol Applications

The Elesa+Ganter 113045 HCK.127 GL level indicator is especially relevant when the fluid is not limited to standard oil. The borosilicate glass tube makes the model more appropriate for water or water/glycol-based solutions than a standard PC oil-only tube. For design teams, this distinction is important because fluid compatibility directly affects service life and inspection reliability.

Practical Engineering Value

This model supports clear visual level reading and temperature event detection in one assembly. The contrast screen improves visibility, the protected glass tube helps maintain readability, and the 80°C NC sensor adds a useful electrical warning point. It is a strong fit for reservoirs, cooling-related circuits, hydraulic systems with glycol mixtures, and industrial machines where simple local inspection must be combined with a defined temperature signal.

Elesa+Ganter 113045 FAQ

What is Elesa+Ganter 113045 used for?

It is used for fluid level visibility and maximum temperature signalling in tanks and reservoirs.

What does GL mean?

GL indicates a borosilicate glass transparent tube suitable for oil, water, or water/glycol-based solutions up to 50%.

What happens at 80°C?

The normally closed temperature contact opens when the preset 80°C temperature threshold is reached.

Is this model the same as a PT100 version?

No. This version has an 80°C temperature sensor with NC contact, not a continuous PT100 temperature probe.
