There are many affecting positioner signals, and one of them is the common skyscraper in daily life. The room is also in the building. Since these buildings are covered with concrete metal, the signals cannot be passed. Apart from the window, the signal can be received. Most of the signals that everyone can see in the room is actually from the LBS base station or Wi-Fi positioning. These three positioning methods have their own advantages and disadvantages, and they cannot change their original characteristics according to the current technology.
It is also the biggest rumor. The call -free card positioner is not not inserted, but the manufacturer has built the card in the device according to needs. Without a card, the device has no signal and cannot complete the signal transmission. And if such a positioning device with a card -free card has a failure, the subsequent maintenance is also very troublesome. For users, this greatly affects the experience.
In the figure, the components of the mechanical pneumatic valve positioner are basically clear. The next step is to see how it works? The gas source comes from the compressed air of the air pressure station. There is also an air filter pressure reduction valve in the front of the valve positioner gas source to compress the purification of the air. From entering the gas source from the depression valve exit from the valve positioner, as for how much gas enters the film head of the valve, it is determined according to the output signal of the controller.
The electrical signal output by the controller is 4 ~ 20mA, and the pneumatic signal is 20kPa ~ 100kPa. From the electrical signal to the air signal, it is performed by an electrical converter. When the telecommunications signal output by the controller transforms to a gas signal corresponding to the corresponding, then the conversion of the conversion gas signal is used on the ripple tube. Leaning 2 will move around the fulcrum, and the lever 2nd section moves to the right to the nozzle to the right.
