Bleed Airflow Sensor GTx116 Transmier EBTRON • 1663 Hwy. 701 S., Loris SC 29569 • Toll Free: 800.2EBTRON (232.8766) • Fax: 843.756.1838 • Internet: EBTRON.com The GTx116-B is EBTRON’s top-of-the-line soluon for accurate, repeatable bi-direconal airflow/temperature measurement with a programmable alarm. This innovave instru- ment accurately measures extremely low airflow rates between adjacent pressure zones and can calculate the equivalent differenal velocity pressure. Operang range is -3,000 to +3,000 fpm or -1.8 to +1.8 iWG. Mounng kits are available for a range of applicaons. ♦ Adjacent zone pressure moni- toring for flow reset. ♦ Underfloor system supply control (to maintain diffuser throw velocity). ♦ Independent, posive control of relief dampers. ♦ Monitor containment/isolaon zones (LEED IEQ applicable). ͵ Actual, standard airflow or equiva- lent differenal pressure output ͵ Altude adjustment ͵ Separate integraon 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 opon available ͵ EB-Link interface opon for re- al-me sensor data download to the EB-Link Reader ͵ Advanced Field Adjust Wizard (FAW) tool ͵ Analog output simulator for BAS in- terface tesng (on analog models) ͵ Three security levels to lock and protect configuraon parameters ͵ Advanced sensor diagnosc system (SDS) Advanced Features Typical Applicaons GTx116-B OVERVIEW GOLD SERIES I-P Units Advantage 3 Bi-directional Differential Airflow Measurement with Temperature and Alarm Bleed differential airflow (equivalent differential pressure) measurement a measurable difference! ® Thermal dispersion technology Bi-direconal airflow measurement NIST-traceable calibraon 0 to +/- 3,000 fpm range Percent-of-reading airflow accuracy Temperature and alarm capability Analog, RS-485, Ethernet or Lon output Installaon/mounng kits available FEP plenum rated cable included 3-year warranty

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.
