1. Can be used for down-range, and the amplitude is controlled within ±50%FS.
2. The maximum pressure of the system should be less than the overload protection limit of the sensor, otherwise it will affect the service life of the product and damage the product.
3. Do not force to pull the pins or the leads of sensitive components.
4. Protect the isolation diaphragm at the front end of the pressure sensitive component to prevent the impact of the pressure sensitive component from damaging the sensitive component.
