MicroTransEQ Airflow Signal Processor
|
|
|
|
|
|
The MicroTransEQ flow transducer utilizes a 24 bit A/D converter for
signal processing and can produce accuracies of ±0.1% of reading. The ultra low
0.03"w.c. differential pressure (693 fpm at standard air density conditions) full
scale operating range and the auto zeroing function provides accurate air flow measurement
down to 100 fpm making this product ideal for outdoor air flow measurement applications
and for use on projects seeking to obtain credit for IEQ Credit 1: Outdoor Air Delivery
Monitoring under the LEED® Green Building Rating System. The MicroTransEQ
also accepts a temperature input signal for air density compensation for standard
or actual airflow calculations. For easy use on fan inlet applications with piezometer
ring systems, the MicroTransEQ incorporates a special piezometer ring
flow algorithm with easy flow coefficient entry through display menus. A 4-point
flow correction and K-factor field menu are included to reduce time and save money
spent on balancing. Device monitoring and configuration can also be performed by
a building management system through either a LonWorks®, BACnet-MS/TP®
Master or Modbus communication network.

|
|
|
FT & FIT-1001 Series are analog two wire differential pressure transducers with
a square root extractor, scaling multiplier, and output filter complete in a single
package. The 4-20 mA output of the transducers is linear to velocity or volume.
Each transducer is factory spanned and calibrated to meet the design requirement
of the application and flow measuring elements being served. Optional features include
local indication of the measured process air velocity and/or volume on either a
0.5 inch high 3-1/2 digit LCD display meter scaled in cfm (Model FIT-1001-D) or
an independent front panel mounted magnehelic pressure gauge scaled in both cfm
and fpm (Model FIT-1001-M), and a built-in three-way manual zeroing valve for ease
of zero verification and calibration (Models FT-1001-ZV, FIT-1001-DZV, and FIT-1001-MZV).

FT & FIT-1003 Series are analog three wire differential pressure transducers
with a square root extractor, scaling multiplier, and output filter complete in
a single package. The 0-5 or 0-10 VDC output of the transducers is linear to velocity
or volume. Each transducer is factory spanned and calibrated to meet the design
requirement of the application and flow measuring elements being served. Optional
features include local indication of the measured process air velocity and/or volume
on either a 0.5 inch high 3-1/2 digit LCD display meter scaled in cfm (Model FIT-1003-D)
or an independent front panel mounted magnehelic pressure gauge scaled in both cfm
and fpm (Model FIT-1003-M), and a built-in three-way manual zeroing valve for ease
of zero verification and calibration (Models FT-1003-ZV, FIT-1003-DZV, and FIT-1003-MZV).

FT & FIT-1005 Series are analog four wire differential pressure transducers
with a square root extractor, scaling multiplier, and output filter complete in
a single package. The 4-20 mA, 0-5 VDC, or 0-10 VDC selectable output of the transducers
is linear to velocity or volume. Each transducer is factory spanned and calibrated
to meet the design requirement of the application and flow measuring elements being
served. Optional features include local indication of the measured process air velocity
and/or volume on an independent front panel mounted magnehelic pressure gauge scaled
in both cfm and fpm (Model FIT-1005-M), and a constant volume purge feature that
prevents contaminants from migrating to the differential pressure sensor (Model
FIT-1005-MCP).
