About PCI Primary Sensors

Paragon Controls Incorporated (PCI) Primary Sensing Elements are designed for use in HVAC airside systems or industrial process control loops. They provide output signals readily convertible to air velocity, air volume, and differential pressures by devices such as indicating meters, transducers and controllers to meet the needs of all commercial and most industrial applications. PCI has been designing and manufacturing primary sensing elements since 1984, and they are now installed worldwide as a part of systems requiring continuous signals for HVAC or industrial automatic control, alarming, and process indication.

All PCI Primary Sensing Elements are multi-point self-averaging devices. The output of the duct-mounted FE-1000 & 2000 series Primary Flow Measuring Elements is differential (velocity) pressure used to indicate airflow quantity at the point of measurement. PE-5000, 6000, 7000 & 8000 Series Primary Pressure Measuring Elements are duct or space mounted, and their output signals are the actual static pressures at the element locations.

The accuracy of PCI's families of FE & PE primary sensing elements has been independently qualified in accordance with the Figure 7 testing procedure of ANSI/AMCA Standard 210-85. However, it is more important to note that the stated accuracy of all PCI devices is constantly being field-validated by independent test and balance firms. Their Balance Reports document conformance to specification and confirm the superior operating performance of PCI commissioned systems.
