Determine the specific installation position of the pressure sensor in order to determine the number and location of the pressure sensor model 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) pressure sensors can be installed only one. (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 fault, except at the beginning of the pressure sensor is installed outside, away from the starting point at 150 ~ 200m automotive pressure sensors, 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. Pressure sensor fault prone transmitter output signal instability. This failure may be the problem pressure source. Pressure source itself is an unstable pressure sensor works, most likely meter or pressure sensor is not strong anti-jamming capability, the sensor itself is very powerful vibration and sensor fault; fourth is the transmitter and the gauge pointer control large deviations. Deviation is a normal phenomenon, confirmed the normal range of variation can be; the impact of differential pressure transmitter installation location for zero output. Differential Pressure Transmitter is very small due to the measurement range, the transmitter will affect the output of the sensing element differential pressure transmitter. The transmitter should be installed so that the pressure-sensitive axially perpendicular to the direction of gravity, after mounting the transmitter zero adjustment to the standard value.
