7 Application Tips

1. The sealing method of the pressure sensor is recommended for the hexagonal ED seal structure. Avoid excessive torque affecting the stability of the pressure sensor during thread installation. The recommended torque is not greater than the following values according to the pressure range: 0~500kPa, 0.9Nm; 500kPa~2MPa, 1.1Nm; 2MPa~10MPa, 1.6Nm.
2. Pay attention to protect the front diaphragm and the compensation circuit board at the back end of the pressure sensor, so as not to damage the performance or cause damage to the sensor.
3. Do not press the metal diaphragm with hands or hard objects to avoid damage to the sensor due to chip deformation or perforation
4. The ventilation pipe at the rear of the G-type sensor should relate to the atmosphere; water, water vapor or corrosive media are not allowed to enter the reference chamber at the rear of the sensor.
5. Avoid falling, hitting, etc., which will affect the stability of the sensor
6. In case of change in the pin lead, the label carried by the sensor shall prevail.
