Description
400B Series Transmitter is a fully independent and self-developed
liquid level measurement product. Its core sensor utilizes a
built-in diffused silicon element.
The product features a fluid dynamics design with an enlarged
bottom filter screen, enabling precise measurement of the liquid
height from the transmitter's end to the liquid surface. It
includes a detachable bottom filter cover to prevent clogging, as
well as an internal air guide tube and a triple-layer protection
process. With its compact size, superior overall performance, and
cost-effectiveness, it is suitable for various harsh environments.
From R&D design, production assembly, calibration, to quality
inspection, every step of our manufacturing process strictly
adheres to international quality production system standards.
