7 Application tips
● Pay attention to protect the front diaphragm of the pressure core and the compensation circuit board at the rear end, so as not to damage the performance of the pressure core or damage the core.
● Do not press the metal diaphragm with your hands or hard objects to avoid damage to the core due to chip deformation or perforation.
● The vent pipe at the rear of the G-type core body should be kept open to the atmosphere; it is forbidden for water, water vapor or corrosive media to enter the reference cavity at the rear of the core body.
● Avoid dropping, bumping, etc., which will affect the stability of the product.
● If there is a change in the pin lead, the actual physical label of the core shall prevail.
