Because the signal starting current of the two-wire transmitter is 4mA.DC, it provides static operating current for the transmitter, and the electrical zero is 4mA.DC on the surface, which does not coincide with the mechanical zero. And the two line system is also easy to use safety grid, conducive to safety explosion-proof. The two-wire transmitter is shown in Figure 1. Its power supply is 24v. DC, output signal is 4-20mA.DC, load resistance is 250Ω, the negative line potential of 24V power supply, it is the signal common line, the intelligent transmitter can also load the FSK keying signal of HART protocol on the 4-20mA.DC signal

It is recommended to select flame-retardant copper BV wire for wire and bushings as well as laying method. "ZC" indicates flame-retardant grade C; Wire specifications: According to the current load selection, usually 16A switch with 2.5mm2BV wire, 20A(25A) switch with 4mm2BV wire, 32A switch with 6mm2 cable, 40A switch with 10mm2 cable; Protective casing: Usually PVC will do. Here we remind you to pay attention to the thickness and quality of the casing (indoor distribution line wiring can use metal conduit or plastic conduit. The wall thickness of the metal pipe should not be less than 1.5mm, and the wall thickness of the plastic pipe should not be less than 2.0mm); The laying way of wires is usually as follows :WC: dark laying in the wall CC: dark laying in the ceiling ACC: dark laying in the inaccessible ceiling FC: dark laying in the ground SCE: dark laying in the ceiling, through the metal pipe wire, phase line/neutral line/control line should be separated by a unified color, protection line with yellow and green two-color line; ⑥ Wire pipe selection table, to prevent workers in the construction of the same casing again into too many wires, affecting the transmission of current load, such as PC20 casing * multiple set of 6 single core 2.5mm2 BV wire, PC20 tube * multiple set of 5 single core 4mm2 BV wire.
