Pressure Sensors Transducers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact pressure span, output protocol version, and presence or absence of auxiliary components such as NTC inputs. Ensure the selected variant matches the system requirements for master/slave configuration and calibration curves prior to procurement.

Pressure Sensors Transducers Selection Notes

Select this component when a relative pressure measurement within the -0.3 to 1.0 bar range is required with digital SENT output. The PCB-less form factor is suitable for direct integration into tight spaces where traditional packaged sensors are unsuitable. Consider the ASIL B compliance if the application demands functional safety certification.
