CTD504 Adjustable Differential Pressure Switch Product Description CTD Differential Pressure Switch is an electron-mechanical device that used for sensing a difference in pressure between two pressure sources in a plant or system for control purposes. CTD Differential pressure switches will make a changeover when pressure differential between two sources falls below a preset value, it will reset when pressure differential rises back to a certain value: preset value plus dead band (appr 0.3bar). The applicable media could be air, water, Freon, hydraulic oils, gases, steam, and etc.
