Elesa+Ganter 113049 HCK.127-ZN-M12-NBR-GL-P-STL PT100 Electrical Level Indicator

The Elesa+Ganter 113049 PT100 electrical level indicator is a technical fluid monitoring component for industrial hydraulic and lubrication systems. Its full designation, HCK.127-ZN-M12-NBR-GL-P-STL, shows that it combines a 127 mm column level indicator with a borosilicate glass tube and an STL PT100 temperature electrical probe.

Technical Construction

The HCK.127 body uses a 127 mm hole centre distance and M12 fixing thread. The assembly ends are produced from black glass-fibre reinforced polyamide-based technopolymer. The support is aluminium, and the white lacquered aluminium contrast screen improves visibility of the fluid column. This structure helps maintenance teams read fluid level from outside the reservoir without interrupting machine operation.

GL Tube and NBR Sealing

The GL code indicates a borosilicate glass transparent tube suitable for oil, water and water/glycol-based solutions up to 50%. The NBR O-ring is intended for maximum continuous working temperatures up to 100°C. For many hydraulic applications, this combination offers a practical balance between visibility, sealing performance and compatibility with common industrial fluids.

PT100 Temperature Probe

The STL suffix identifies the PT100 temperature electrical probe. Unlike a simple temperature switch, a PT100 probe provides a resistance-based temperature signal that can be interpreted by compatible measuring equipment. This makes the Elesa+Ganter 113049 HCK.127-ZN-M12-NBR-GL-P-STL electrical level indicator suitable for systems where temperature trend monitoring is more useful than only receiving an on/off alarm.

FAQ

What is the product type of Elesa+Ganter 113049?

It is an electrical level indicator with a visual column display and an STL PT100 temperature probe.

What is the benefit of a PT100 probe?

A PT100 probe enables temperature measurement through resistance variation, allowing a connected system to track fluid temperature more precisely than a basic switch.

Is this model suitable for glycol-based fluids?

Yes. The GL borosilicate glass tube is designed for oil, water and water/glycol-based solutions up to 50%.

Why choose this instead of an 80-NO version?

Choose the STL version when continuous or interpreted temperature measurement is preferred. Choose 80-NO when a simple normally open temperature threshold signal is enough.
