The GTx116-B is EBTRON’s top-of-the-line solution for accurate, repeatable bi-directional

airflow/temperature measurement with a programmable alarm. This innovative instru-

ment accurately measures extremely low airflow rates between adjacent pressure zones

and can calculate the equivalent differential velocity pressure. Operating range is -3,000

to +3,000 fpm or -1.8 to +1.8 iWG. Mounting kits are available for a range of applications.

♦ Adjacent zone pressure moni-toring for flow reset.

♦ Underfloor system supply control (to maintain diffuser throw velocity).

♦ Independent, positive control of relief dampers.

♦ Monitor containment/isolation zones (LEED IEQ applicable).

͵ Actual, standard airflow or equiva-lent differential pressure output

͵ Altitude adjustment ͵ Separate integration buffers for the

display and output ͵ High or low airflow/pressure or

trouble alarm ͵ Two isolated analog outputs (flow

and temperature or alarm) plus one network output are standard on RS-485 and Ethernet models (BTL Listed BACnet, or Modbus)

͵ Lon output option available ͵ EB-Link interface option for re-

al-time sensor data download to the EB-Link Reader

͵ Advanced Field Adjust Wizard (FAW) tool

͵ Analog output simulator for BAS in-terface testing (on analog models)

͵ Three security levels to lock and protect configuration parameters

͵ Advanced sensor diagnostic system (SDS)

1 Installed airflow accuracy is the actual system accuracy expected and includes sampling uncertainty of the bleed sensor when installed without tubing. Accuracy and performance on installations with tubing will vary based on tubing, and field adjustment is recommended in these applications.2 Sensor accuracy is the calibrated accuracy of the individual sensor. The installed accuracy of the overall airflow station is application-dependent.
