The WNK7 series transmitter is a pressure measurement transmitter with superior performance developed and manufactured by our company through the introduction of advanced foreign technology and equipment. All key raw materials, components, and parts are imported, and the entire machine has undergone strict assembly and testing; It has the characteristics of advanced design principles, beautiful appearance, complete variety and specifications, and complete compatibility with similar foreign products in installation and use. This series of products is widely used in industries such as petroleum, chemical, textile, power, food, paper, medicine, cement manufacturing, etc.
The WNK75 intelligent differential pressure transmitter is mainly used for:
Measurement of absolute pressure, gauge pressure, and differential pressure of gases, vapors, or liquids in various process control fields;
• Measurement of liquid level, volume, or mass;
• Measure the flow rates (volume flow rate and mass flow rate) of gases, vapors, and liquids in conjunction with detection components;
