Assembly & Ordering Guidelines
- Ensure proper fit between core size and transmitter housing for required airtightness
- Align housing vertically and apply even pressure during assembly to avoid damaging compensation plate
- Provide special instructions if measured medium is incompatible with 316L diaphragm material
- Avoid pressing sensor diaphragm with hands or sharp objects to prevent damage
- Keep gauge pressure port open to atmosphere and prevent entry of water or corrosive media
- Refer to actual core label for pin lead configuration
