cảm biến áp suất Pressure Sensor PCB 105C
[1] Zero-based, least-squares, straight line method.
[2] Due to high sensitivity, the static pressure should be applied and removed very slowly. Rate should prevent more than 10 Volt change in output until Output Bias Voltage returns to normal (approximately 15 times discharge time constant).
[3] See PCB Declaration of Conformance PS023 for details.
