1. Perform a sanitary cleaning once a week to keep the transmitter and its accessories clean;
2. Check the pressure piping and valve joints for leaks once a week. If there is leakage, it should be treated as soon as possible.
3. Check the transmitter parts intact every month, no serious corrosion and damage; the nameplate and logo are clear and correct; the fasteners should not be loose, the connectors are in good contact, and the terminal wiring is firm;
4. Check the on-site measurement line once a month, including whether the input and output circuits are intact, whether the line is disconnected, short-circuited, and whether the insulation is reliable.
5. Check the accuracy of the zero point and display value of the instrument every month. The zero point and display value of the transmitter are accurate and true.
6. Calibrate regularly according to the transmitter calibration cycle.
7. Periodically discharge, condense or vent the transmitter.
8. Periodically fill the isolation fluid for the transmitter with the isolation fluid from the source line or measuring component.
9. Regularly purge the pressure guiding tube of the easily blocked medium.
10. When the transmitter is deactivated for a long time, the door should be closed once.
11. When the pressure transmitter is in use, its housing must be well grounded. The transmitter used to protect the system should have measures to prevent power failure, short circuit, or open circuit.
12. In the winter season, the instrument should be inspected and the source pipeline is well insulated, so that the source pipeline or the measuring component of the transmitter is damaged by freezing (the southern climate temperature is high, generally no pipeline is required.
