HART Field Device
HVP valve positioner is a kind of field equipment used to control the valve opening, which can quickly and stably control the valve opening.
HVP valve positioner is a current input device with low power consumption. It can work by providing 4-20mA current signal for the device.
The working principle is to collect valve position data and input current signal through AD module, convert the collected data into valve position percentage and input command percentage. Through the deviation between input command and valve position signal, it is controlled by intelligent software algorithm Control IP unit for air intake or exhaust, so as to achieve the purpose of controlling valve positionIn addition, through communication equipment, HVP valve positioner can also realize remote monitoring, control and other functions.
