The Scigiene Wireless Professional Gen 2 Differential Air Pressure Sensor measures the pressure difference between two input ports and transmits the measurement to Scigiene Premiere. When viewing the sensor from the top, the right inlet port is the negative or low side pressure input. When the pressure on this port is greater than the left port the sensor produces a negative pressure reading. When the pressure is greater on the left port the sensor produces a positive pressure reading.
