  • Page 17: Principle Of Operation

    Electro-Pneumatic Positioner SP 520 Series _________________________________________________________________________________________________________ 2-8 Principle of Operation  (1) LINEAR TYPE  When the input signal (4~20mA) is input, the input current is transmitted to the coil of the Torque Motor (1) and magnetic force is generated in the core. Move to the left. As a result of the action, the gap between the nozzle (17) and the spring support (5) is opened, and the pressure in the nozzle pressure chamber (18) drops, resulting in a pressure difference with the pressure chamber (19).
  • Page 18 Electro-Pneumatic Positioner SP 520 Series _________________________________________________________________________________________________________ (2) ROTARY TYPE  When the input signal (4~20mA) is input, the input current is transmitted to the coil of the Torque Motor (1), and magnetic force is generated in the core. With this magnetic force, the flapper (4) receives the force to the right and the spring support (5) is Move to the left.
