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