|
1. Pay attention to the fit between the core size and the
transmitter housing during assembly to achieve the
required airtightness
2. During the assembly of the housing, ensure it is aligned
vertically and apply even pressure to avoid jamming or damaging the
compensation plate.
3. If the measured medium is not compatible with the core diaphragm
and the housing material (316L), special instructions should be
provided when placing the order.
4. Avoid pressing the sensor diaphragm with hands or sharp objects
to prevent damage to the core due to diaphragm deformation or
piercing.
5. Keep the pressure port of the gauge pressure core open to the
atmosphere and prevent the entry of water, water vapor, or
corrosive media into the core negative pressure chamber.
6. If there are any changes to the pin leads, follow the label on
the actual core for reference.
