EK Engineering

Working Principle:

Fischer NS01 is microprocessor based level switch with integrated interface. In addition to its integrated change-over function, it suits sensitivity of the device to dielectric quality of the media. Formation of crusts and drainage behaviour can be visualised and controlled by using the software process diagram. Key features are switching points and – especially therefore separated setting of hysteresis to suit process.
The adjusted value is reproducible by additional actions like dynamic compensation of temperature.
When NS01 comes in contact with the medium, high frequency alternating field is used for level measurement. It is bought to process through an on-media side isolated PEEK-socket. The device is integrated into the process through socket welding or modular adaption.
The alternating field launched into process is changed by dielectric qualities of the medium (dielectric constant). This causes a change in interpretation of sensor. Medium detection is performed by switching an electric output.
