Elesa+Ganter 113025 Electrical Level Indicator with NC Contact and PT100 Probe

Elesa+Ganter 113025 electrical level indicator, listed as HCK.127-ZN-M12-NBR-PC-P-E-NC-STL, is engineered for industrial fluid level monitoring where visual inspection, minimum-level electrical signalling, and temperature feedback are required in a compact assembly. The model belongs to the HCK.127 configuration, which indicates a 127 mm hole centre distance and M12 threaded fixing.

Construction and Readability

The indicator is built with black glass-fibre reinforced polyamide-based technopolymer assembly ends, a natural aluminium support, and a white lacquered aluminium graduated contrast screen. This screen improves readability of the liquid column and can be removed before assembly for custom markings. The transparent polycarbonate tube is intended for oil, while the removable polycarbonate front protection helps shield the column from accidental impacts and simplifies cleaning.

NC Contact Logic

The NC contact is one of the most important features of this model. In a normally closed configuration, the electrical contact opens when the minimum level is reached. This logic is often preferred in systems where interruption of a circuit must indicate a low-level condition. It can support preventive maintenance strategies because a level drop can be detected before the tank reaches a critical operating state.

PT100 Probe for Temperature Monitoring

The STL suffix identifies a PT100 temperature electrical probe. The probe works by measuring the resistance variation of a platinum element, which allows the control system to interpret fluid temperature. This is especially relevant in hydraulic and lubrication systems, where temperature changes can affect viscosity, seal performance, and long-term machine reliability.

Where It Fits Best

The Elesa+Ganter 113025 electrical level indicator is suitable for hydraulic units, machine reservoirs, oil tanks, and equipment where operators need both a direct visual level check and an electrical signal. Its NBR O-ring configuration supports standard industrial oil applications with a maximum continuous working temperature of 100°C for the sealing material.

Elesa+Ganter 113025 FAQ

What makes Elesa+Ganter 113025 different from a simple sight glass?

It combines a visual level column with an electrical minimum-level sensor and a PT100 temperature probe, giving both local and system-level feedback.

What does NC mean?

NC means normally closed. The contact opens when the minimum level is reached.

Does the 113025 include temperature measurement?

Yes. The STL designation indicates a PT100 temperature electrical probe.

Can it be used in hydraulic systems?

Yes, it is commonly selected for hydraulic and lubrication reservoirs, provided the liquid and working conditions are compatible.
