The main contents of daily maintenance and inspection of Yokogawa transmitters

Yokogawa transmitterDuring the application process, maintenance and inspection are required to ensure that the instrument operates normally for many years. For example, patrol inspection, which mainly includes the condition of instrument indications and whether there are any abnormalities in the instrument readings; Is the air source pressure of the pneumatic transmitter normal; Is the power supply voltage normal; In addition, there are environmental temperature, humidity, and cleanliness conditions; It is necessary to check for any leaks, corrosion, or other issues between the instruments and process interfaces, as well as between the pressure pipes and valves.

The regular maintenance of Yokogawa transmitters includes: regular calibration and zero point inspection; Regularly carry out condensate discharge, sewage discharge, and emptying; Regularly inject isolation fluid and blow the pressure pipes that are prone to blockage. Check the quality of instrument use to ensure accuracy and flexibility. The indication error and static pressure error must be within the allowable range and not exceed the standard. In addition, the contact of the connectors should be good, the terminal wiring should be firm, the instrument components should be intact and free of serious rust, damage, etc., and the fasteners should not show any signs of loosening. These behaviors help Yokogawa transmitters leverage their advantages and become good partners in the industrial field.
