Display Level Transmitter and Switch DLF 8980
The operating principle of the DLF 8980 is based on a chain of reed contacts arranged inside the measuring rod. The reed contacts are activated by a permanent magnet located within the float, which changes its height with the level of the media. A continuous float level instrument consists of one float moving along the whole stem length between the upper and lower stop. The position of the float is evaluated by the electronics to control the outputs accordingly.
