Ordering Tips
Ensure proper fit between core size and transmitter housing for required airtightness
During housing assembly, maintain vertical alignment and apply even pressure to avoid damaging the compensation plate
Provide special instructions if measured medium is incompatible with 316L diaphragm and housing material
Avoid pressing sensor diaphragm with hands or sharp objects to prevent damage
Keep gauge pressure core port open to atmosphere and prevent entry of water, vapor, or corrosive media
Refer to actual core label for any pin lead changes
