7 Application tips
1. pay attention to protect the compensation circuit board at the rear end to avoid touching and affecting the performance of the pressure sensor or causing damage to the core.
2.  keep the ventilation pipe at the rear of the G-type sensor connected to the atmosphere; prohibit water, water vapor or corrosive media from entering the reference chamber at the rear of the sensor.
3.  avoid dropping, hitting, etc., which can affect the stability of the product.
If there is any change in the pin lead, the label carried by the sensor shall prevail.
