Transducer Location
Place head assembly in an area of ductwork that will
provide an average and evenly distributed airflow pattern.
Use the following guidelines to determine an appropriate
installation location.
1. Locate static head assembly approximately 2/3 to 3/4
the way down longest duct run, in an area
approximately 10 duct diameters downstream and 2
duct diameters upstream of major interferences, turns,
or changes in duct diameter.
2. When installing pneumatic tubing between head
assembly and transducer in control panel, do not
exceed 250ft for 1/4" OD tubing or 500ft for 3/8" OD
tubing.
Installing the Transducer
Use the following procedure to properly install the static
pressure transducer:
1. Mount pressure sensing head assembly in duct with
sensing tip is in middle of the duct so that it will provide
a proper pressure measurement. See
2. Connect the pneumatic tubing from the sensing head to
the push-on tubing connection in the control panel. Use
a plastic static pickup tubing. Do not exceed 250 feet
for 1/4" OD tubing or 500 feet for 3/8" OD tubing.
Transducer inside control panel picks up low side or
reference pressure.
