NivoCapa in heated vegetable oil

The Challenge

One of the leaders in the food market in the Caribbean needed an accurate level measurement solution with an instantaneous output signal, which complies with hygienic requirements to install in a 3 meter tank made of stainless steel for storage of palm oil, which has a very low dielectric constant, heated between 165- 180°C, due to the viscosity of the material. Also, internally the process produces steam and is pressurized to 1.1 Bar.

Our Solution

We solved this case with capacitive transmitters NivoCapa series 8000, equipped with active shield and inverse frequency shift measurement technologies. These sensors were adjusted to operate up to 200°C by a system of electronic distance from the heated surface of the tank, and still supports 35 Bar overpressure. The food-grade PA-coated probe met the necessary hygienic requirements. This solution was perfect, even in the case of a viscous product such as palm oil in a steamy environment, since the capacitive principle is very precise and with quick update of the output signal.
