Submersible Level Transmitter ND101

Product Overview

The Submersible Level Transmitter ND101 utilizes a high-performance diffused silicon piezoresistive pressure sensor as its sensing element to provide accurate and reliable liquid level measurement.

The sensor measures the hydrostatic pressure generated by the liquid column, which is proportional to the depth of the liquid. Through an integrated signal conditioning circuit, the measured pressure is converted into a standard current or voltage output signal, establishing a precise linear relationship between the output signal and the liquid level.

Featuring a compact design, high measurement accuracy, and IP68 waterproof protection, the transmitter can be directly immersed into the liquid for continuous level measurement. Its simple installation and stable performance make it suitable for a wide range of industrial liquid level monitoring applications.

Operating Principle

The Submersible Level Transmitter measures ND101 liquid level based on the hydrostatic pressure principle.

As the liquid level changes, the pressure exerted on the submerged sensor changes proportionally. The built-in diffused silicon piezoresistive sensor converts this pressure into an electrical signal, which is processed by the internal signal conditioning circuit and output as a standard analog signal (current or voltage).

Because hydrostatic pressure is directly proportional to liquid depth, the transmitter accurately determines the liquid level for continuous monitoring and control.
