Smart valve positioner, dust explosion-proof ExtD, angular stroke, double acting, fail lock, stainless steel corrosion-resistant, split body anti-high temperature vibration

Input components: one of the seven major parts of the conventional mode of the hardware structure of the intelligent valve positioner. It is used to connect the current control signal (input given value) and accept the feedback signal from the valve position sensor to the control valve stroke detection, and support the primary function of positioning control. For HART signal mode, the FKS modem is set in the input loop for HART digital signal separation. For field bus types such as Profibus-PA and FF that accept digital control signals, there is no current input in the input component, but the external bus network is connected through the communication interface. The valve position feedback signal is to transmit the valve position to the valve position sensor through the control valve stem (shaft) through the feedback rod and other mechanical connecting parts. Resistive displacement (angle) sensor.
