In hydraulics and lubrication technology the liquid level of oil tanks must be monitored continuously. In the process, modern factory automation requires the provision of compatible signals. To minimise production costs and the space required on tanks, it makes sense to use one monitoring device for both the monitoring of the liquid level and oil temperature for example. The Nivotemp series meets virtually all requirements arising in this area of application. The NT 63 model either provides only one continuous liquid level signal or continuous signals for temperature and liquid level. The interface for the tank is DIN 24557 T 2 standardised.
