Description
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.
