- Ensure proper fit between core size and transmitter housing during assembly to achieve required airtightness
- During housing assembly, maintain vertical alignment and apply even pressure to avoid jamming or damaging the compensation plate
- If the measured medium is not compatible with the core diaphragm and housing material (316L), provide special instructions when ordering
- Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage from deformation or piercing
- Keep the pressure port of the gauge pressure core open to the atmosphere and prevent entry of water, water vapor, or corrosive media
- Refer to the label on the actual core for any pin lead configuration changes
