    What is the liquid level transmitter, what is its wiring method?

     

    The level transmitter is the transmitter. It is only measured by pressure to measure its height instrument. The measurement principle is: Pressure difference = density * g * h, the pressure difference can be known that G is known to know that the density is known, and it can be reversed H, which is the height of the liquid level. Applying this principle to measure the level transmitter of the level, it is the liquid level transmitter. The pressure transmitter is a device that converts the pressure of the gas or liquid into an electrical signal that can be used. The pressure transmitter can be divided into two-wire, three-wire, four-wire system. It should be a quad-line pressure transmitter. Two power cords, two signal lines. The power supply is connected 24V direct power, and the simple detection method is to use a current table or a voltage meter, and the signal line is connected to both ends. After the power is connected, the current table will have a 4mA current or a voltage meter with a 0V or 1V voltage. The current transmitter generally has four terminals, two are wiring, and two other two do not wireless, the transmitter's DC24V power cord is 4 ~ 20mA signal feedback line, that is, your second time Table or DAS (Data Acquisition System) AI point to with DC24V output.
