Principle Characteristic
NFS22 baffle-type flow switch is a new structure flow switch developed by our company's researchers specializing in flow and differential pressure meters to analyze the shortcomings of current flow switches in the market. It follows the simple and reliable design concept, and greatly improves the reliability of flow switches from the structure, which can be compared with non-traditional target flow switches. Plug - in installation, mechanical flow switch. Built-in micro trigger switch. Minimal pressure loss, good repeatability,anti-fouling ability, through the knob to achieve accurate switching Settings.
The mechanical part is securely isolated from the electronic part. The product does not contain bellows which are easy to cause faults. The electrical parts do not directly contact with metal parts with large temperature difference, and there is no problem that the electrical parts will produce condensate water and lead to corrosion. It has a variety of types for customers to choose to adapt to different applications. The use of imported micro switch as an electrical action part, through the current is large, completely avoid the use of magnetic switch improper easy to damage the problem, is the central air conditioning and industrial fluid control of the preferred flow protection products.
Product Application
Gas-liquid dual-use, can be widely used in industrial automation/mechanical equipment/air compression industry/refrigeration and air conditioning field. Flow switch magnets are not in flowing waterways and can be used in sewage systems and work properly.
