Elesa+Ganter 113775-KN HCK.127-A4-M12-FKM-PC-P-EHT-NC-STL-KN Oil Level Indicator
The Eleşa+Ganter 113775-KN HCK.127-A4-M12-FKM-PC-P-EHT-NC-STL-KN oil level indicator is designed for industrial oil reservoirs where visual level inspection, electrical minimum level signalling and temperature monitoring are required in one compact component. Its configuration includes a 127 mm centre distance, M12 connection, FKM sealing rings, a polycarbonate transparent tube, an EHT high-temperature float, a normally closed level contact and a PT100 temperature probe.
Construction and Functional Design
The A4 designation is associated with stainless fixing hardware, supporting applications where resistance to corrosion and long service life are important. The FKM O-rings improve sealing performance in higher temperature oil environments, while the PC level tube provides a clear reading point for maintenance staff during daily inspections.
The front protection is made from polycarbonate and can be removed for cleaning. This is useful in plants where oil mist, dust or residue may reduce visibility over time. The white contrast screen behind the column helps operators read the fluid level more easily, even when the tank is installed in a less accessible machine area.
Elesa+Ganter 113775-KN Sensor Logic and Temperature Feedback
The EHT float is designed for higher continuous temperature conditions than standard level sensor floats. The NC electrical contact opens when the fluid reaches the minimum level threshold. This behaviour is commonly used in machine safety logic, preventive maintenance systems and control panels where a low-level event must be clearly detected.
The STL part of the code identifies the PT100 temperature probe. This probe measures temperature through resistance variation and helps users monitor oil condition, thermal stability and operating consistency.
Where It Is Used
This indicator is suitable for hydraulic units, lubrication tanks, industrial machinery and oil-based systems requiring reliable visual and electrical supervision. For related components, see the Elesa+Ganter product information page.
Elesa+Ganter 113775-KN FAQ
What makes Elesa+Ganter 113775-KN different?
It combines oil level visibility, NC minimum level signalling and PT100 temperature measurement in a single column level indicator.
What is the role of the FKM seal?
FKM sealing rings provide improved resistance to heat and many industrial fluids compared with standard rubber options.
Can the indicator be used in hydraulic oil tanks?
Yes, the PC tube version is intended for oil-based applications when the operating conditions match the product limits.
What does EHT mean?
EHT refers to the high-temperature float execution used for minimum level sensing.
Why is normally closed contact preferred in some systems?
NC logic allows the circuit to change state when the minimum level is reached, which can be useful for alarms and control systems.
