Oil Level Gauge for Construction Machinery

Oil Level Gauges and Level Indicators on Hydraulic Tanks

• Oil level gauges: visual indication of oil level at the hydraulic tank
• Level indicators: defined visible range depending on design
• Electrical variants: versions with switching point or sensor function

Differences lie in length, visible range, mounting pattern, fixation and overall design.

Length, Mounting Dimensions and Visible Range

The length defines the readable range inside the tank and must match the installation position.

Deviations shift the visible range or make the oil level unreadable in operation.

Mounting Pattern, Fixation and Design

Critical factors are hole spacing, mounting points and the design of the existing tank interface.

Deviations in mounting pattern or overall height prevent installation or lead to leakage.

Mechanical and Electrical Designs

Mechanical versions operate through direct visual indication. Electrical variants extend level monitoring with defined switching points or sensor-based signals.

These designs differ in function and construction and are not interchangeable.

Typical Deviations in Practice

• Length: not aligned with tank height or installation position
• Mounting pattern: not matching the existing fixation points
• Design: mechanical and electrical versions not compatible
• Installation position: visible range does not reflect actual oil level

Incorrect selections become apparent during installation or operation.

Position within Hydraulic Filter Accessories

Oil level gauges are part of hydraulic filter accessories and belong to tank-mounted components within the hydraulic system.

Related components in the same accessory range include clogging indicators and filter heads. Tank-related systems also include fill and breather filters.
