Among the many instruments and meters, the transmitter is the most widely used, and the related types and accessories are relatively complete, and how to choose the transmitter is also the most common concern for us. The following methods are of good reference value for the selection of transmitters and accessories. For transmitters there are several options for special environments: 1. In flammable and explosive working conditions, explosion-proof transmitters should be selected. 2. For medium that is easy to crystallize, scarring, clogging, viscous and corrosive, a flange transmitter should be selected. Materials that are in direct contact with the medium must be selected according to the characteristics of the medium. 3. In a humid environment, a transmitter with a high protection level must be selected to avoid water ingress into the transmitter and burns the components. Selection of accessories for the transmitter to use: 1. When the transmitter measures water vapor and medium with a temperature greater than 6 °C, a spiral or U-shaped elbow should be selected. 2. When measuring easily liquefied gas, if the pressure point is higher than the instrument, a separator should be selected. 3. When measuring dust-containing gases, dust collectors should be selected. 4. When measuring the pulsating pressure, a damper or buffer should be selected. 5. When the ambient temperature is close to or lower than the freezing point or freezing point of the measuring medium, thermal insulation or heating tracing equipment should be adopted. 6. For pressure switches and transmitters installed in the open air, transmitter protection boxes should be selected.
