Wiring sensor has always been one of the procurement process consulting clients have the most problems, many customers do not know how to connect the sensor pressure sensor manufacturers, in fact, a variety of sensor wiring are basically the same, pressure sensors generally have a two-wire , three-wire, four-wire, and some have five-wire system. Two-wire pressure sensor is relatively simple, general customers know how wiring, a cable to connect the positive power supply, and the other line is the signal line through the instrument is connected to the negative power supply, which is the most simple, three-wire pressure sensor is in two Wire added based on a line, this line is directly connected to the negative power supply, compared with two-wire a little trouble. Four-wire pressure sensor must be two power inputs, the other two are the signal outputs. Four-wire voltage output instead of mostly 4 ~ 20mA output, 4 ~ 20mA called pressure transmitter pressure sensor, most made of two-wire system. Some of the pressure sensor output signal is amplified without full-scale output is only tens of millivolts, and some internal pressure sensor amplifier, full-scale output of 0 ~ 2V. As to how to the display meter, depending on the range of the instrument is how much, if any, and the output signal compatible gear, you can directly measure the pressure sensor supply, or to add signal conditioning circuitry. Five-wire and four-wire pressure sensor or less, five-wire sensor market is relatively small. Determine the specific installation position of the pressure sensor in order to determine the number and location of the specific installation, adjustment of each inflatable inflatable network segment to consider. (1) pressure sensors must be installed along the cable, it is best to install the cable joints. (2) Each cable is less than four pressure sensors installed near the telephone office of two pressure sensors, distance should not be a big 200m. (3) the start and end of each cable were installed one. Branch point (4) of each cable should be installed one, if the two branch points are in close proximity (less than 100 m), only one can be installed. (5) cable laying methods (overhead and underground) change should be installed at a (6) of the non-branching cable, because cable program consistent base line gauge pressure sensor installation is not dry 500m, and Its total less than four. (7) In order to facilitate the determination of the pressure sensor failure points, in addition to the pressure at the start of the pressure sensor is installed outside the sensor parameters, from the starting point at 150 ~ 200m, but also to install a course in the design, we must consider the economic and technical factors, in no need to install a pressure sensor place, you should not have to be installed.
