Elesa+Ganter 113067 Electrical Level Indicator with NC Contact and PT100 Probe
Elesa+Ganter 113067 electrical level indicator, listed as HCK.127-ZN-M12-NBR-GL-P-E-NC-STL, is designed for hydraulic systems that need a readable fluid level column, minimum-level electrical detection and temperature feedback in one compact assembly.
Product Overview
The HCK.127 format indicates a 127 mm hole-centre distance, making this model suitable for smaller or medium-size hydraulic reservoirs. Its M12 mounting connection supports straightforward integration into machinery where standard threaded mounting points are already used. The indicator combines mechanical visibility with electrical feedback, which is useful when both local inspection and remote system response are required.
Technical Structure
The assembly ends are made from black glass-fibre reinforced polyamide based technopolymer. The support is natural aluminium, while the graduated contrast screen is white lacquered aluminium and can be removed before assembly if users need to add level marks or operating references. The GL tube is borosilicate glass, selected for use with oil, water and water/glycol-based solutions.
This version uses NBR O-rings, generally associated with a maximum continuous working temperature of 100°C. The P designation indicates removable polycarbonate front protection, which helps protect the level column and simplifies cleaning. The STL suffix identifies a PT100 temperature probe, giving the machine control system a way to read fluid temperature trends.
How the NC Contact Works
The NC contact is normally closed during standard operating conditions. When the fluid reaches the minimum threshold, the contact opens. This behaviour is often selected for monitoring circuits where interruption of the signal is used as an alarm condition. For critical hydraulic applications, NC logic can be useful because wiring faults and low-level states may be easier to detect in some control architectures.
Industrial Use Cases
Common applications include hydraulic power packs, injection moulding machinery, press systems, lubrication units, automated production equipment and industrial tanks. By combining visual level indication with electrical monitoring, the unit supports preventive maintenance routines and reduces dependence on manual checks alone.

Elesa+Ganter 113067 Electrical Level Indicator Frequently Asked Questions
What is the main purpose of Elesa+Ganter 113067 electrical level indicator?
It is used to show fluid level visually while also providing an electrical minimum-level signal and temperature measurement through the PT100 probe.
What does NC mean in HCK.127-ZN-M12-NBR-GL-P-E-NC-STL?
NC means normally closed. The contact opens when the fluid reaches the minimum level threshold.
Is the GL tube suitable for glycol-based fluids?
Yes. The GL version uses borosilicate glass and is intended for oil, water and water/glycol-based solutions.
Why is the PT100 probe useful?
The PT100 probe helps monitor fluid temperature, which is important in hydraulic systems where overheating can affect viscosity, pump performance and seal life.
Can it be used without remote monitoring?
Yes. The visual column still allows local level inspection, but the electrical functions are valuable when the machine also needs automated low-level or temperature monitoring.
