Description
The 400B Series Transmitter is a self-developed solution for liquid
level measurement, featuring a core sensor with a built-in diffused
silicon element for improved accuracy.
This device incorporates a fluid dynamics design with an expanded
bottom filter screen, enabling precise measurement of liquid levels
from the transmitter to the surface. It also includes a detachable
bottom filter cover to prevent clogging, along with an internal air
guide tube and a triple-layer protection process.
With its compact size and exceptional overall performance, the 400B
Series is well-suited for various demanding environments. Our
manufacturing process—from R&D design through production
assembly, calibration, and quality inspection—adheres strictly to
international quality production standards.
