  1. Ebtron GTx116-P+ High-performance airflow measurement with temperature & alarm capability 24 Oct 2014

  2. Overview • Thermal dispersion technology • 0 to 24.5 m/s range • 2% of reading sensor airflow accuracy • Mounting options for internal, insertion or standoff • Custom built • 3-year warranty

  3. Temperature Sensing Thermistor m ) ( rvd kA B + C Q = (TH – TA) m d Self-heated Thermistor How an Ebtron Works Heat dissipated to the airstream is directly related to the velocity and mass velocity. velocity DT Power

  4. = + + Probe Uncertainty Transmitter Uncertainty Conversion Error Accuracy Each thermistor is individually wired to transmitter using FEP plenum rated cable DDC system calculates velocity for control process Many host control systems can directly accept our RS-485, Ethernet or Lon outputs V Q Output Application Controller Converted back to analog with a DAC Airflow Digitally processed 10101011 Converted to binary with an ADC 10101011 …… Each signal is multiplexed The high level output is converted to binary by an ADC in host control system Self-heated thermistor Sensor cal Data is stored in “one-wire” memory Zero-power thermistor
