NOTE:
1. During assembly, pay attention to the coordination of the core
size and the transmitter housing to achieve the required air
tightness.
2. During the housing assembly process, ensure that it is
vertically aligned and apply even pressure to avoid jamming or
damaging the compensation plate.
3. If the medium under test is incompatible with the core diaphragm
and housing material (316L), special instructions should be
provided when placing the order.
4. Avoid pressing the sensor diaphragm with hands or sharp objects
to avoid deformation or puncture of the diaphragm and damage to the
core.
5. Keep the pressure port of the gauge core open to the atmosphere
to prevent water, water vapor or corrosive media from entering the
negative pressure chamber of the gauge core.
6. If there is any change in the pin, please refer to the label on
the actual product.
