HPM420W split-type submersible liquid level transmitter is designed for accurate measurement of liquid levels and depths. It utilizes a high-performance silicon piezoresistive pressure sensor as the measuring element. This sensor accurately measures the hydrostatic pressure, which is directly proportional to the liquid level and depth.


The measured pressure is then converted into a standard current or voltage signal output through a signal conditioning circuit. This establishes a linear relationship between the output signal and the liquid depth, enabling precise measurement of the liquid level.


The HPM420W transmitter offers high precision and a compact size, making it suitable for various applications. The probe can be directly immersed into the liquid to measure the liquid height from the end of the transmitter to the liquid level. It is user-friendly and finds application in liquid level measurement and control in areas such as petroleum, chemical industry, power plants, urban water supply, and hydrological exploration.


Before delivery, the product undergoes rigorous screening for long-term aging and stability. This ensures its reliability and stability, making it suitable for use in open spaces with harsh environmental conditions.
