Pressure sensor maintenance and verification
The application of pressure sensor detection requires maintenance personnel to carry out regular inspections, including whether various pressure guiding tubes leak, whether the cleaning medium is normal, whether the insulation is good, etc. As long as the maintenance is good, a large amount of ordinary pressure sensors can save a lot of investment. Pay attention to the combination of hardware maintenance and soft maintenance during maintenance. The pressure sensor is preferably in the form of a threaded connection, which saves money and is easy to install. The selection of the pressure sensor must also take into account the corrosiveness of the measured medium, but the temperature of the medium used can not be considered, because the common type is pressed into the meter, and the temperature is normal temperature during long-term operation, but the maintenance of the common type is used. The amount is larger than the isolation type. The first is the insulation problem. When the temperature is below zero, the pressure guiding tube will freeze. The pressure sensor can't work or even be damaged. This will increase the heat tracing and incubator. At high temperatures, heat dissipation or other measures are required to perform sensor pressure measurement. When the pressure sensor is selected for detection, a normal type pressure sensor can be used as long as it is not a crystallization medium, and a purge medium can be added for indirect measurement for a low pressure and easy crystallization medium (as long as the process allows the use of a purge liquid or gas).
Mercedes pressure sensor maintenance. The pressure transmitter is required to be inspected once a week, once a month, mainly to remove the dust inside the instrument, carefully check the electrical components, and the current value of the output should be checked frequently. The internal pressure of the pressure transmitter is weak. Separated from the outside world.
