7 Application tips
- Taking care to protect the front diaphragm of the pressure sensor and the compensation circuit board at the rear end so that the performance of the pressure sensor will not be affected or the pressure sensor will be damaged by bruising.
- Do not press the metal diaphragm with hands or hard objects to avoid damage to the pressure sensor due to chip deformation or perforation.
- Keep the rear vent pipe of the G-type pressure sensor connected to the atmosphere; prohibit water, water vapor or corrosive media from entering the reference chamber at the rear of the pressure sensor.
- Avoid dropping and bumping, etc., which will affect the stability of the product.
- If there is any change in the pin lead, the label carried by the pressure sensor shall prevail.
