Note: The electrical connection is based on the connection marked on the product parameter card.
1. Dashed left arrow resistance bridge circuit for the sensitive chip bridge.
2. without ceramic compensation board, an external resistor to compensate for zero and temperature drift, the connection as shown. Access to    zero resistance R3 (R4), another resistor R4 (R3) shorted as negative power supply; R1 or R2,only one for the zero temperature drift compensation resistor, the another one opens, Choose according to the information provided by the parameter card; R5 is for the sensitivity of temperature compensation resistor, it is recommended that the external compensation resistor be as close as possible to the pressure sensitive element.

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.
7. If you have special requirements on product performance parameters and functions, please contact us.
