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 core diaphragm and housing material (316L)
  • 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
  • Refer to actual core label for any pin lead changes
