-
During assembly, ensure proper fit between the core and transmitter housing to meet specified airtightness requirements.
-
When assembling the housing, maintain vertical alignment and apply even pressure to prevent jamming or damage to the compensation plate.
-
If the measured medium is incompatible with the core diaphragm or housing material (316L), special instructions must be provided at the time of order placement.
-
Do not touch the sensor diaphragm with hands or sharp objects to avoid core damage caused by deformation or puncture.
-
For gauge pressure cores, keep the pressure port vented to the atmosphere and prevent moisture, steam, or corrosive media from entering the negative pressure chamber.
-
Always refer to the labeling on the physical core for pin lead connections, especially if modifications have been made.
