Description
The 1140_1B Absolute Air Pressure Sensor 20-400 kPa is a gas pressure sensor that measures the absolute pressure of its environment. It can measure pressures from 20 kPa to 400 kPa.
This sensor is designed to measure the pressure of clean, non-condensing air. Contact with moist air (i.e, human breath), dusty air, or other gases can damage the sensor.
The Absolute Gas Pressure Sensor provides an accurate, high level analog input signal that is proportional to the environment’s pressure. The minimum pressure measurement for this sensor is 20 kPa. Any value lower than 20 kPa cannot be accurately distinguished. Ports The sensor port has a diameter of 2.79mm to 3.30 mm (nominal 3mm).
1140_0 Absolute Pressure Sensor 20-400 kPa Formulas
The Formula to translate SensorValue into Pressure is: {Pressure (kPa)}= (SensorValue)/{9.2} + 10.652 {Pressure (psi)} = (SensorValue)/{63.45} + 1.54 Note: 1.0 kPa = 0.145 psi
