Liquid Level Sensor WPCK81

  • WPCK81(1).png


WPCK81 series general-purpose liquid level transmitter is a new patented submersible liquid level measurement product. It uses high-quality imported monocrystalline silicon as the core component. After the company's strict production process and quality management system, as well as sophisticated Testing equipment, providing customers with a new type of high-stability submersible liquid level measuring instrument. At the same time, the company has accumulated a wealth of experience through the application of this product, which can enable customers to provide more assured selection and use, and meet the actual production needs. The company will provide strong technical support for this.


* All stainless steel 316L design, protection class IP68
* Can realize medium liquid level, temperature dual output mode
* Anti-interference, anti-lightning design
* The transmitter probe has the functions of preventing deposition, preventing sharp objects from being stabbed, and preventing the growth of marine organisms.
* Can measure high temperature media
* More than 2 times overvoltage, the range below 5 meters can reach 5 times overvoltage
