Product Overview

The 400B Series Transmitter is a fully independent and self-developed liquid level measurement solution. It incorporates a core sensor with a built-in diffused silicon element.

Designed with fluid dynamics in mind, this product features an enlarged bottom filter screen that allows for precise measurement of liquid height from the transmitter to the surface. It includes a detachable filter cover to prevent clogging, an internal air guide tube, and a triple-layer protection system. Its compact size, exceptional performance, and cost-effectiveness make it suitable for a variety of harsh environments.

Every step of our manufacturing process—from research and development to assembly, calibration, and quality inspection—strictly adheres to international quality production standards.
