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 enhanced accuracy.

This device incorporates a fluid dynamics design with an enlarged bottom filter screen, allowing for precise measurement of liquid levels from the transmitter to the surface. It also includes a detachable bottom filter cover to prevent clogging, alongside an internal air guide tube and a triple-layer protection process.

With its compact dimensions and exceptional overall performance, the 400B Series is well-suited for a variety of demanding environments. Our manufacturing process—from research and development to production assembly, calibration, and quality inspection—strictly follows international quality production standards.
