Product Recommendation: YX643T5H33 Liquid Level Relay

Ten-Function Liquid Level Relay

YX643T5H33


The Ten-Function liquid level relay YX643T5H33 is a modern device that integrates ten core functions and can achieve precise, stable and intelligent control of liquid levels. It is not simply equipped with ten isolated functions, but through the organic synergy of these functions, it forms a complete closed-loop system ranging from liquid level detection to control execution, from safety protection to intelligent management.


Product  &  Features

Ten Functions

In the field of liquid level control, the reason why the ten-function liquid level relay YX643T5H33 has become a highly favored "intelligent manager" lies in its integrated ten practical functions. These functions range from basic liquid level monitoring to complex safety protection, comprehensively covering the liquid level control requirements in different scenarios.





Adjustable Sensitivity

Among the numerous key features of liquid level relays, the sensitivity adjustment range of 5K - 200KΩ is undoubtedly the "secret weapon" that enables them to precisely adapt to various complex liquid level detection scenarios. This broad and fine adjustment range provides a solid guarantee for the stable and accurate operation of the liquid level relay in different liquid environments.



Dual Delay Independently Adjustable

The Ten-Function liquid level relay is like an intelligent "buffer master". The E1 and E2 positions on the shell are clearly marked with a scale range of 0.1 to 30 seconds. Just rotate the knob to the corresponding scale according to the actual application scenario requirements, and the delay time can be set.




Application  &  Fields


YX643T5H33 Ten-Function liquid level relay is suitable for various occasions such as civil, industrial, agricultural, sewage treatment and so on.
