FAQ
What interface does the DFP300I use?
It uses an IIC communication interface for pressure and temperature data output.
What supply voltage is listed in the selection guide?
The guide lists 1.8 V to 3.6 VDC input and a default 3.3 V selection option.
Does the guide include assembly notes?
Yes. It recommends a floating assembly structure and protecting the front isolation diaphragm.
Technical Data & Selection Guide
Measurement range: 0-100 kPa…100 MPa
Input voltage: 1.8 V-3.6 VDC
Pressure accuracy: +/-0.5%FS
Output: 15%-85% over IIC bus protocol
Protection: IP65
Selection Guidance
DFP300I uses an IIC digital interface, not a 4-20 mA loop. Confirm the controller interface and low-voltage supply before integration. The guide recommends floating assembly without compression sealing on the sensor end face. Protect the isolation diaphragm, and confirm the seal configuration for temperatures below -20 deg C or harsh media.
