• 1478512-1 application field and working principle

1478512-1, also known as the valve positioning feedback transmitter, is designed to provide feedback control for multi-position valve actuators and other similar systems. The device is connected with a secondary element, such as a potentiometer, which feeds an analog signal to a position sensor or other apparatus. The device measures position, velocity, and acceleration of the actuators and/or secondary element. It can be used as part of a system to sense and control cylinder position, pressure, temperature, motor speed, dampening coefficients, force, and other parameters.1478512-1 offers a variety of design features that enhance accuracy and reliability. Its feedback loop consists of a power supply, signal conditioner, and position transducer. The power supply provides power to the signal conditioner, which processes the signal from the position transducer and provides a control signal to the actuator based on the input received. The position transducer is the element which determines the actual position of the actuator.1478512-1 is an ideal device for use in a variety of industrial applications, particularly those involving the control of multi-position actuators. Its design features allow it to work reliably in a wide range of environments, even in extreme conditions such as high temperatures and pressure changes. Additionally, it is designed to be able to handle a variety of analog and digital signals, including pulse width modulation (PWM) signals.The principle behind the operation of the 1478512-1 is relatively straight-forward. When a voltage is applied to the position transducer, a signal is created which is sent to the signal conditioner, which then processes the signal and outputs a control signal to the actuator. The actuator then responds to the control signal, causing the position of the actuator to change. The position transducer then feeds back an updated signal to the signal conditioner, which can then adjust the control signal to the actuator to adjust its position further. This feedback loop is repeated until the desired position is achieved.The signal conditioner also has the ability to apply a feedback gain to the control signal to help ensure a more rapid convergence of the feedback loop. Additionally, some models are equipped with a dampening circuit which helps to ensure that the position does not rapidly fluctuate and that the feedback loop reaches convergence more quickly.In summary, the 1478512-1 is a reliable and versatile device for providing feedback control of multi-position actuators. Its signal conditioning capabilities help ensure precise feedback control and make it an ideal choice for a wide variety of industrial applications. Its feedback loop consists of a power supply, signal conditioner, and position transducer, and its dampening circuit ensures rapid convergence of the feedback loop.
