Level gauges for hydraulic power units – Frequently Asked Questions
What are level gauges for hydraulic power units and what are they used for?
Level gauges are measuring devices for monitoring the oil level in hydraulic reservoirs. They allow precise monitoring without having to open the tank, thereby contributing to operational safety and efficiency. Many models also display the oil temperature.
How do level gauges for hydraulic power units work?
The functionality depends on the type of sensor:
- Float mechanisms: Mechanical or electrical transmission of the float position
- Capacitive sensors: Measure changes in electrical capacitance caused by the oil
- Pressure sensors: Determine the level via hydrostatic pressure
- Hall effect sensors: Contactless and low-wear detection of magnetic changes
- Optical display: Visually indicates the fluid level
What materials are level gauges made of and how are they installed?
Level gauges are made of durable materials for use in hydraulic systems:
- Housing and flanges: Steel or aluminum, often corrosion-protected
- Sensors: Stainless steel, plastic, or ceramic
- Seals: NBR or FKM for reliable sealing
- Installation: Mounted on the tank with standard flanges, as a replacement for tank covers, or on flange openings
What advantages do level gauges for hydraulic power units offer?
The use of level gauges provides several benefits:
- Continuous monitoring of the oil level
- Timely detection of low levels, preventing failures
- No need to open the tank → protection against contamination
- Optional integrated temperature display
- Robust design for long service life
Where are level gauges used and what sizes are available?
Level gauges are versatile in application:
- Stationary and mobile hydraulic power units
- Mechanical engineering, agriculture, construction, industrial plants, mobile machinery
- Available in various sizes and installation lengths, matched to tank volume and application
- Standardized flange sizes facilitate integration into existing systems
What about the maintenance and service life of level gauges?
Level gauges are low-maintenance, but the following are recommended:
- Regular visual and functional checks
- Inspection for leaks and intact electrical connections
- Mechanical models: floats can be wear parts
- Electronic sensors (e.g., Hall or pressure): generally longer-lasting
- Service life: typically 5–15 years, depending on operating conditions
Which factors are decisive when selecting the right level gauge?
Several criteria are decisive for the selection:
- Compatibility with hydraulic oil
- Environmental conditions (temperature, vibrations)
- Installation situation and flange size
- Desired additional functions such as temperature measurement
- Robust design, easy installation, and availability of spare parts
