Description

The 400C Series Transmitter is an economical solution for liquid level measurement, built upon the foundation of the 400A series, and featuring a built-in diffused silicon sensor core.

This device employs a fluid dynamics design with a unique arc-shaped housing, effectively minimizing medium disturbances while ensuring high reliability. It includes a detachable bottom filter cover to prevent clogging, as well as an internal air guide tube and a triple-layer protection process.

In comparison to the 400A series, the 400C is more compact, provides enhanced performance, and remains highly cost-effective, making it well-suited for a range of challenging environments.
