APPLICATION
YPL Pressure Indicating Controller is very versatile, reliable and accurate Pressure instrument to satisfy modern process control requirements. The indicating controller is used for control of liquid, gaseous or vaporous media. The instrument senses the pressure of the measured medium directly & display the operating value, compares the measured variable with the set point and gives pneumatic signal in the standard range 0.2 to 1 kg/cm². This output pressure actuated the final control element. YPL Pressure Indicating Controlling may include ON-OFF, Proportional only, Proportional with Automatic Reset(Integral), Proportional with Auto Reset And Pre-Act control responses.
