'T' Probes for Small Duct & VAV Terminal Box Applications
Ebtron developed the thermal dispersion `T' probe products for challenging terminal box and small duct applications. Ebtron thermal dispersion technology provides a significant advancement over conventional differential pressure based flow rings that are typically installed in these applications. Smaller ducts, with a large duct wall-surface to free-area ratio, produce erroneously higher than actual flow readings when traditional multi-point traverse techniques are used.
Ebtron `T' probes - which are physically smaller to their `P' probe counterparts - feature a proprietary flow loss compensation design. Ebtron `T' probes are computer calibrated between 0 and 3,000 fpm (0 and 15.2 m/s) in individual wind tunnels to volumetric airflow standards. As a result, performance on smaller ducts is greatly improved by compensating for flow losses near the duct wall. Ebtron thermistors used at each sensing point location provide accuracy in "percent of reading" (not "percent of full scale") throughout the entire calibrated range.
Ebtron `T' probes are supplied with either Silver or Hybrid transmitters with robust electronics and features and are calibrated for single or two-sensor probe applications (regardless of the input maximum of the transmitter).
