The enterprise standard for explosion-proof flow switches mainly refers to their attributes produced as explosion-proof standards, which can pass the explosion-proof environment detection standards. Of course, its usage scenario will depend on the specific type of flow switch.
For example, paddle flow switches are specifically designed for flow monitoring of water sources, water cycle heat pump air conditioning systems, and heat pump water heaters.
The NK33EX series explosion-proof flow switch from Zhanke is mainly used for flow interruption alarm and pump protection.
What are the characteristics of explosion-proof flow switches:
*Good repeatability
*Low pressure loss
*Anti fouling
*Explosion proof
*Airtight separation of electrical and hydraulic components
*Beautiful appearance
*Installing a protective cover can achieve waterproofing
*The NK33 series can be paired with corrosion-resistant and long probe rods

The national standards for explosion-proof flow switches mainly include three main standards: GB3836.1-2010, JB/T9329-1999, and GB/T 14048.1-2006, which cover the general requirements for equipment and the explosion-proof enclosure; drsquo; Protective parts, transportation and storage of instruments and meters, basic environment and testing methods, general principles for low-voltage switchgear and control equipment. Detailed specifications have been established in several aspects. You can refer to relevant detailed information or contact our company’s engineers for specific details.
The above is the content of the enterprise standard for explosion-proof flow switches.
The NK33EX series explosion-proof flow switch products from Zhanke comply with relevant national requirements and technical standards. If you are interested in it, please feel free to contact NOIKE engineers for consultation.
