Abstract: An automated communicating system continuously derives differential pressure relative to a reference and provides a user display of this value. The system may include, among other elements, a remote transmitter, multiple receiving devices, a visual display, pre and post processing algorithms, a user interface to input a pressure set point, and a one or more air quality sensors. A differential pressure is derived from two absolute pressure readings, resulting in a determination of space over- or under-pressurization relative to a set point. Post-processing algorithms and filters are applied to the final output data stream prior to visual display of the space over- or under-pressure conditions. Calibration may be based on a zeroization method to determine an offset value used by the pressure algorithm to address differences between absolute pressure sensors production offsets, drift, and altitude differences between the physical placement of the two absolute sensors.

Abstract: Systems and Methods for Differential Pressure Determination and Control are disclosed. In one aspect, embodiments of the present disclosure include a system, which able to obtain pressure measurements. The system can include, a sensor and a processor coupled to the sensor. A further embodiment includes memory coupled to the processor where the memory has stored thereon instructions, which when executed by the processor, cause the processor to: determine, a local set of pressure measurements from the sensor and/or compare the local set of pressure measurements with an external set of pressure measurements.
