General

Probe and Sensor Node Configurations (max.)

1 probe x 4 sensor nodes/probe
2 probes x 2 sensor nodes/probe

Installed Airflow Accuracy¹

≤ 2 sq.ft. [0.185 sq.m.]: [0.18 sq.m]: ±3% of reading

> 2 sq.ft. [0.185 sq.m.]: ±(3% to 10%), typical (increases with increasing duct size). May be improved by field adjustment using the Field Adjust Wizard (FAW) to a reliable reference.

¹Installed airflow accuracy allows for additional uncertainty that results from averaging a finite number of sensors in a contorted velocity profile created from up and downstream disturbances. The specified installed accuracy is based on the PE sensor density rules for installations that meet or exceed EBTRON minimum placement requirements. PE sensor density rules may not be available for all duct sizes due to sensor placement limitations (see PE sensor density tables for more information).

General

Probe and Sensor Node Configurations (max.)

1 probe x 4 sensor nodes/probe 2 probes x 2 sensor nodes/probe

Installed Airflow Accuracy¹

≤ 2 sq.ft. [0.185 sq.m.]: [0.18 sq.m]: ±3% of reading

> 2 sq.ft. [0.185 sq.m.]: ±(3% to 10%), typical (increases with increasing duct size). May be improved by field adjustment using the Field Adjust Wizard (FAW) to a reliable reference.
