All wetted materials are selected to give a high level of media compatibility. Media compatibility refers to media inside the pressure port and lid. Improved media compatibility on high pressure port (backward side of sensor chip) since media has no contact to electronic components. Nevertheless tests with the media used in the specific application are recommended. 2. Sensor is specified in air, changes in sensor behaviour based on physical effects caused by the specific media can occur. Weight of the media and wetting forces can influence the sensor characteristics. 3. Storage temperature of the sensor without package. 4. Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the sensing element. 5. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure. 6. Non-linearity refers to the Best Straight Line fit, measured for offset pressure, full scale pressure and 1/2 full scale pressure. 7. Not for all pressure ranges. Please contact First Sensor if operating temperature range -40...+125 °C is required. 8. Tested 1h, up to 85 °C. Sensors are electronic components and should be handled only in ESD save environments.
