Edition 02/2001







Technology Overview


604 Pressure Switcher is used as air pressure difference switcher in air duct to control filter and fan. Besides, it is also used in primary and secondary control system of air door.







604 Pressure Switcher is also suitable for preventing heater coil from superheating as well as monitoring industrial air-refrigerating circuit.







Measuring medium: air and non-corrosive gas.
