- Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the required airtightness
- During the assembly of the housing, ensure it is aligned vertically and apply even pressure to avoid jamming or damaging the compensation plate
- If the measured medium is not compatible with the core diaphragm and the housing material (316L), special instructions should be provided when placing the order
- Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage to the core due to diaphragm deformation or piercing
- Keep the pressure port of the gauge pressure core open to the atmosphere and prevent the entry of water, water vapor, or corrosive media into the core negative pressure chamber
- If there are any changes to the pin leads, follow the label on the actual core for reference
