Introduction
A limit switch, also known as a feedback device, is actually an instrument that displays (reflects) the status of a valve switch. At close range, we can visually observe the current open/close status of the valve through the "OPEN"/"CLOSE" on the limit switch. When remotely controlling, we can know the current open/close status of the valve through the open/close signal feedback from the limit switch displayed on the control screen.There are four main types of valve limit switches: mechanical limit switches, inductive proximity sensors, spring limit switches, and limit switches
The limit switch mechanism is compact, combining the filter and pressure reducing valve in one unit. Good particle separation, high flow rate, low hysteresis, and good regulation characteristics. Two pressure adjustment ranges: 0.5... 7 bar and 0.5... 12 bar. Two types of pressure gauge interfaces, flexible installation. Equipped with manual, semi-automatic or fully automatic condensate discharge. By locking the rotating handle, the settings are protected from tampering.
Valve feedback switch (limit switch) is a field instrument used in automatic control systems to detect the status of valves. It is used to output the opening or closing position of valves as a switch signal, which is received by the program controller or sampled by the computer. After confirmation, the next step of the program is executed. This product can also be used as an important valve interlock protection and remote alarm indication in automatic control systems.
The appearance design is novel and beautiful, with a three-dimensional position indicator that can clearly identify and display the position of the valve. The internal 8-contact internal circuit PCB board wiring is convenient to prevent short circuits. The control method can be selected according to the requirements of the on-site environment, including proximity switches, magnetic switches, and signal feedback devices.
