摘要： A filter monitoring device for an air flow system is described herein, which comprises a circuit board comprising a first pressure measurement component and a second pressure measurement component, and including hardware and software configured to communicate pressure measurements to a remote computer. The device also includes a sensor comprising a first pressure sensor component comprising a first tube having a first end portion configured to be connected to the circuit board and a second end portion configured to be connected to a first location in the air flow system upstream from and external to a filter media compartment, and a second pressure sensor component comprising a second tube having a first end portion configured to be connected to the circuit board and a second end portion configured to be connected to a second location in the air flow system downstream from and external to the filter media compartment. Corresponding systems and methods also are disclosed.

摘要： A differential pressure monitor is disclosed herein, which comprises a controller comprising a processor disposed in a housing, and a memory storing instructions that, when executed by the processor, cause the processor to pre-calibrate a first pressure sensor and a second pressure sensor before initial use, and subsequently, determine the differential pressure between the first and second sensors during use of the sensors, and display an indicia representative of the differential pressure between the first and second sensors. Corresponding methods and systems also are disclosed.
