AC20C pressure transfer module series with a compact structure is easy to install, whose specifications could provide strong compatibility between sensitive components and the measured medium, excellent medium adaptability and long-term stability. The pressure transfer module could directly output what you need such as standard voltage, current, or digital signals. Because its PCB is fixed on the mounting bracket, pressure sensor needs a little installation room and provides strong anti-vibration performance. In terms of its ruggedness, pressure transfer module is widely implemented in various fields.

Selection tips:
1. The tested medium should be compatible with the materials in contact with the product.
2. For other requirements, please consult us and indicate what you need in the orders.
3. The rights to make technical modifications like its circuit structure and shape are reserved without prior notice.
Note:
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.
5. If you have special requirements on product performance parameters and functions, please contact us.
