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.

Level- and temperature switch NV 74

  • up to 4 wireless, adjustable level contacts
  • Various plug options
  • Connecting flange as per DIN 24557 T2
  • 24 V standard, 230 V upon request
  • Temperature monitoring as switch, Pt100 or 4-20┬ámA output

Level and temperature switch with display NV 74D

  • easy to read LED display with status of the switching outputs
  • 2 wireless, adjustable level contacts
  • up to 4 programmable temperature switching outputs
  • Connecting flange as per DIN 24557 T2

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.

The NV 74 model can be equipped with a max. of four adjustable, wireless bistable level contacts or two level and two different temperature signals for liquid level monitoring. An LED display for temperature monitoring with up to four programmable switching outputs is optional or alternatively, one continuously analogue output and one switching output (can also be programmed as a frequency output).
