Pressure Sensors Transducers Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or discontinuation risks. Confirm that the specific suffix corresponds to the required pressure span and lack of NTC input. Ensure compatibility with existing SENT receiver interfaces and validate mechanical mounting requirements for the SIP module package before finalizing procurement orders.

Pressure Sensors Transducers Selection Notes

Select this model when a differential pressure measurement within the 0.2 to 0.8 bar range is required without external calibration. The absence of an integrated NTC thermistor distinguishes it from variants offering temperature compensation inputs. Choose this part for applications prioritizing high accuracy over life and robust EMC performance in harsh automotive environments.
