Pressure sensor installation considerations

Air pressure telemetry system by the terminal equipment and wiring equipment ( Pressure sensors, the terminal is located in the interior, its role is to line equipment power supply) Automatic measurement, display and print cable pressure values. Line equipment in line, its function is to convert electrical signals sent to the terminal device, and line equipment is a major means of intake air pressure information, it occupies a pivotal position in the air pressure telemetry system. So, line equipment quality, high and low precision, to reduce the maintenance workload and simplify whipped check process is directly related to the pressure.

also need to pay attention to the installation position of pressure sensor, in order to determine the number and the specific installation location of pressure sensor, need according to the gas network of various inflatable period of consideration.

( 1) Branch points each cable should be 1, if two branch points closer apart ( Less than 100 m) Can be only one.

( 2) Laying cable way change should hold one.

( 3) For no branching cables, because the base line of cable program, the installation of the pressure sensor separation not gets 500 m, and make the total number of not less than four.

( 4) Pressure sensor must be installed along the cables, it is better to install the cable joint.

( 5) The beginning of the each cable and terminal installation 1 respectively.

( 6) To determine the pressure sensor fault points, in addition to outside the starting point to install pressure sensors, 150 ~ 200 m from the starting point, and the other one, of course, in the design, installation must consider the factor of economy and technology, in place, do not need to install the sensor should be not installed.

with air pressure telemetry equipment production, the pressure sensor is also used on cable. For the normal work of the air pressure telemetering system, pressure sensor need to match with air pressure telemetry equipment, coordination. From pressure telemetering system, ways of working to have a run-off dot '' line selection and' line selection type two kinds. The pressure sensor failures, be sure to refer to a reasonable solution.
