Elesa+Ganter 113649 HCK.127-SST316-M12-NBR-GL-P-80-NO Oil Level Indicator

The Elesa+Ganter 113649 oil level indicator is a HCK.127 column type indicator with a normally open 80°C temperature sensor. It is designed for applications where a visual fluid level display and an electrical temperature signal are required from the same tank-mounted component.

Technical Specification Overview

This product uses a 127 mm hole centre distance and M12 threaded fixing. Its stainless execution includes AISI 316 fixing components, making it suitable for installations where corrosion protection is a key design factor. The GL transparent tube is borosilicate glass, protected at the front by removable polycarbonate. NBR O-rings provide sealing for standard oil applications up to 100°C continuous working temperature.

Normally Open 80°C Monitoring

The “80-NO” configuration identifies a normally open temperature contact. This can be useful when the control logic expects a circuit to close at a specified thermal condition. In hydraulic power units, this style of signal can support alarms, interlocks or operator warnings.

Why Visual Level Monitoring Still Matters

Even in automated systems, a direct sight glass remains valuable. It lets maintenance teams confirm fluid level without opening the reservoir or relying only on electronic readings. The contrast screen improves readability, while the column format helps operators understand whether the tank is underfilled, correctly filled or overfilled.

Elesa+Ganter 113649 FAQ

What does NO mean in this model code?

NO means normally open. The electrical contact is open in its normal state and changes according to the sensor condition.

What fluids can the GL tube support?

The GL borosilicate tube is intended for oil, water and water-glycol based solutions up to 50%, subject to application verification.

Does the product only measure temperature?

No. It visually displays fluid level and also includes an 80°C normally open sensor function.

Where is this product commonly used?

It is commonly used in hydraulic tanks, lubrication reservoirs, industrial machinery and compact fluid power units.
