Note:
1. Electrical connection is a "soft wire" product, the wire length can be customized according to customer requirements.
2. Can be used for down-range, and the amplitude is controlled within ±50%FS.
3. 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.
4. 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.
5. The commonly used compensation method for the product is 1.5mA constant current compensation. It is recommended to give priority.
6. Do not force or pull the pins of sensitive components.
