Ordering tips

1. Pay attention to the matching of the core size and the transmitter housing during assembly to achieve the required air tightness.
2. During assembly, ensure the vertical alignment and apply even pressure to prevent jamming or damaging the compensation plate.
3. Keep the gauge pressure core air duct connected to the atmosphere and prevent water, water vapor, or corrosive media from entering the positive and negative pressure chambers of the core.
4.If there are any changes in the pin lead, refer to the label attached to the core for accurate identification.
