Elesa+Ganter 113739-NP-KN HCK.127 Oil Level Indicator
Product Overview
The Elesa+Ganter 113739-NP-KN oil level indicator is an HCK.127 column level indicator configured for industrial oil monitoring. The complete code, HCK.127-A4-M12-FKM-PC-NP-STL-KN, identifies a 127 mm installation format, M12 fixing, FKM sealing, polycarbonate tube, no front guard, and STL temperature probe specification.
This model is used where operators need a direct visual reading of oil level while also integrating temperature feedback into maintenance or control routines. Its compact 127 mm format makes it suitable for hydraulic reservoirs, lubrication systems, and machinery with limited panel space.
Key Technical Characteristics
The assembly ends are based on glass-fibre reinforced polyamide technopolymer. The support is aluminium, and the contrast screen improves level visibility. The white background helps make the fluid column easier to read from different angles.
The FKM O-ring is designed for higher temperature use than standard NBR alternatives. This makes the model a practical choice for oil systems where thermal stability, seal reliability, and long service intervals matter.
NP Version Without Front Protection
The NP configuration means the indicator does not include the removable transparent front protection. This can be useful where the installation environment is clean, protected, or already shielded by the machine body. However, in exposed areas, engineers should consider whether a protected version would be more appropriate.
PT100 Probe Configuration
The STL element refers to the PT100 temperature electrical probe. This probe works by measuring resistance change in a platinum element. It is commonly used where temperature data must be integrated into a monitoring system.
During installation, cable routing matters. Temperature signal quality can be affected by nearby electric motors, high-power cables, switchgear, or other noise-generating equipment.
Application Areas
The Elesa+Ganter 113739-NP-KN HCK.127 oil level indicator is suitable for hydraulic power units, lubrication skids, compact oil tanks, industrial presses, packaging machinery, and general mechanical systems requiring reliable visual oil inspection.
