Shift is relative to 25C. 2. Shift is within the first hour of excitation applied to the device. 3. Non-linearity refers to the Best Straight Line fit, measured for lowest specified pressure, highest specified pressure and 1/2 full scale pressure. 4. Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure. 5. Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the sensing element. 6. Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to the housing. 7. The common mode pressure for the HCLA series is 2 bar. Common mode pressure is the maximum pressure that can be applied to both ports of a differential pressure sensor simultaneously without damaging the sensor housing. 8. Max. delay time between pressure change at the pressure die and signal change at the output. 9. The response time depends on the adjusted internal A/D resolution of the sensor. For 12 bit it is typ. 0.5 ms. Other A/D resolutions and reponse times are available on request. Please contact First Sensor for further information. 10. Sensors with lower current consumption are available on request. Please contact First Sensor for further information. E / 11629 / G 2/15 www.first-sensor.com
