Elesa+Ganter 113133 HCK.127-ZN-M12-FKM-PC-P-80-NC Oil Level Indicator

Technical Overview

The Elesa+Ganter 113133 oil level indicator, identified by the stock code HCK.127-ZN-M12-FKM-PC-P-80-NC, is a column-type level indicator designed for hydraulic tanks, lubrication units, oil reservoirs, and industrial machine systems where visual fluid monitoring is essential. Its 127 mm hole centre distance makes it suitable for compact installations, while the M12 screw thread supports secure mounting in demanding mechanical environments.

Material Structure and Application

This model uses zinc-plated steel screws and fixing elements, combined with glass-fibre reinforced polyamide technopolymer assembly ends. The transparent PC tube is intended for oil applications, allowing operators to inspect the fluid level quickly from the front or side. The removable polycarbonate front protection helps protect the viewing column and can be removed for cleaning operations.

The FKM sealing system, commonly associated with Viton-type performance, supports applications where higher resistance to temperature and oil exposure is required. For standard HCK oil use, the maximum continuous working temperature is 100°C, while the integrated electrical temperature sensor is set to 80°C with normally closed contact logic.

Elesa+Ganter 113133 Why NC Contact Matters

The NC, or normally closed, contact configuration is often preferred where a circuit should remain closed during normal operation and change state when the temperature threshold is reached. In practical terms, this supports machine monitoring, preventive maintenance, and safer hydraulic operation. The Elesa+Ganter 113133 HCK.127-ZN-M12-FKM-PC-P-80-NC oil level indicator is therefore not only a visual component, but also a useful monitoring element for industrial fluid systems.
