| Ordering tips |
1. Ensure proper clearance between the core and transmitter housing during assembly to meet specified airtightness requirements.
2. When assembling the housing, maintain vertical alignment and apply uniform pressure to prevent binding or damage to the compensation plate.
3. If the measured medium is incompatible with the core diaphragm or housing material (316L), please provide specific notes when ordering.
4. Do not press the sensor diaphragm with hands or sharp objects, as deformation or puncture may cause internal damage to the core.
5. Keep the gauge pressure core vented to the atmosphere and prevent moisture, vapor, or corrosive substances from entering the negative pressure chamber.
6. If pin wiring is modified, always refer to the label attached to the actual core for correct connections.
