Level- And Temperature Switch Nivovent NV 74/ NV 74D

Fluid Control
The oil tank is the key component of hydraulic and lubrication
systems. The operating oil is removed from the tank and then
returned to it. Depending on what the system is used for, the
levels in the oil tank can fluctuate to varying degrees. In most
applications, the level fluctuations result in an exchange of the
vapour phase above the oil level with the ambient air.
Therefore, virtually all oil tanks are equipped with a so-called air
breather, to prevent contaminants in the ambient air from
entering the system.
To reduce costs and space requirements, a number of other
system-related functions such as liquid level and temperature
monitoring are also combined in the air breather in the
Nivovent series.
