7 Application Tips
- The "floating" sealing structure of side wall O-ring is recommended for the sealing mode of pressure core body, so as to avoid the compression of front end face and affect the stability of pressure core body.
- Pay attention to protect the front diaphragm and the compensation circuit board at the back end of the pressure core body, so as not to damage the performance of the pressure core body or cause damage to the core body.
- The core cavity of the shell shall be designed with a conical angle, which is easy for core assembly and can prevent the seal ring from being scratched by the right angle.
- During assembly, pay attention to the tolerance fit between the core size and the inner shell of the transmitter shell. It is suggested that the cavity should be processed according to + 0.02 - + 0.05 of the core diameter to achieve the required air tightness.
- During assembly, it should be placed vertically and pressed down evenly to avoid jamming or crushing the compensation plate.
- Do not press the metal diaphragm with hands or hard objects to avoid core damage due to chip deformation or perforation.
- When wiring, the core pin should not be cut too short, the length is generally not less than 5mm, and the welding time is not more than 5 seconds.
- The ventilation pipe at the rear of the g-core should be connected with the atmosphere; water, water vapor or corrosive media are not allowed to enter the reference chamber at the rear of the core.
- Avoid falling and bumping, which will affect the stability of the product.
- If there is any change in the pin lead, the label carried by the core shall prevail.
