Rod Float Level Transmitter ND101S Series

Product Description

The rod float level transmitter utilizes a high-performance diffused silicon piezoresistive pressure sensor as the measuring element. It accurately measures the hydrostatic pressure proportional to liquid depth and converts it into a standard (current or voltage) output signal through signal conditioning circuitry, establishing a linear relationship between the output signal and liquid depth for precise level measurement.

Key Features
