Product Description

The 400B Series Transmitter is a fully independent and self-developed liquid level measurement product. Its core sensor utilizes a built-in diffused silicon element for reliable performance.

Featuring a fluid dynamics design with an enlarged bottom filter screen, this transmitter enables precise measurement of liquid height from the transmitter's end to the liquid surface. The detachable bottom filter cover prevents clogging, while the internal air guide tube and triple-layer protection process ensure durability in demanding applications.

With its compact size, superior overall performance, and cost-effectiveness, the 400B Series is suitable for various harsh environments. From R&D design and production assembly to calibration and quality inspection, every manufacturing step strictly adheres to international quality production system standards.
