Selection Examples

Ordering Tips

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 when ordering if measured medium is not compatible 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, vapor, or corrosive media
Reference actual core label for any pin lead changes
