Working Principle
TheRod Float Level Transmitter ND101Suses a diffused silicon piezoresistive pressure sensor to detect the hydrostatic pressure produced by the liquid column.
The measured pressure signal is processed through signal conditioning circuitry and converted into a standard current or voltage output. Since hydrostatic pressure is proportional to liquid depth, the transmitter establishes a linear relationship between the output signal and the liquid level, enabling continuous level measurement.
