Profile: Paragon Controls, Inc. designs & manufactures airflow and pressure sensing elements, transducers, room/space pressure monitoring systems, and control systems. The OAFE-1500 is an AMCA certified outdoor airflow measurement system capable of producing an overall ±0.5 percent accuracy through the velocity range of 200 to 1,200 fpm. The airflow measurement system consists of an integral signal processor and multipl airflow elements, factory mounted and pre-piped in a casing designed for flanged connection to ductwork, control dampers and louvers. An optional inlet bell is available for plenum applications. The signal processor accepts a temperature input signal for air density compensation for standard (scfm) or actual (acfm) airflow calculations. The MicroTrans™ signal processor utilizes current state-of-the-art digital microprocessor technology capable of producing overall ±0.1 percent accuracy with unequaled 20-bit (1,048,576 steps) A/D and 12 bit (4,096 steps) D/A signal conversion resolution. Having a twelve-point linearization capability, the MicroTrans™ can accurately determine true airflow rates even when the primary airflow measurement stations do not meet their minimum installation requirements. The ultra low 0.04 inch w.c. differential pressure, 800 fpm full scale operating ranges and the auto zeroing function of the MicroTrans™ provides accurate airflow measurement down to 100 fpm. This accepts a temperature input signal for air density compensation for standard or actual airflow calculations.
