EF-x1000-T — integral small round-duct transmitter

EBTRON’s EF-x1000-T is aimed at approximately 4–16 inch circular ducts with an integral probe/transmitter arrangement. Correct duct diameter, insertion depth and upstream/downstream disturbances matter more than choosing a generic sensor based solely on maximum airspeed. Confirm whether the ordered electronics provide analog or RS485 data, and verify host scaling and duct airflow-calculation assumptions. It is not a direct mechanical substitute for a multipoint HTx116-P array or remote-display x2000.

The details below are specific model or order-family properties taken from the original equipment maker. For each installed unit, suffix, test conditions and revised documentation govern.

AttributeManufacturer dataEngineering significance
TechnologyCalibrated thermistor thermal-dispersion with single insertion probeDirect velocity/flow sensing unlike static differential pressure.
Round duct size4–16 in (102–406 mm) standard configurationsProbe size and 1/2 sensor-node arrangement depend on diameter.
Range and accuracyManufacturer lists 0–3,000 FPM, ±3% of reading installed accuracy when installation criteria are metThe stated installed performance already includes sampling uncertainties under prescribed placement.
CalibrationSeven-point, NIST-traceable airflow calibration described by OEMA traceable calibration process is not a substitute for duct installation acceptance.
InterfacesAnalog or RS485 by selected x1000 variant; BACnet/Modbus are limited to EF-N1000-TDo not assert Ethernet/IP or a universal combined analog/network interface.
Probe temperature capabilityTemperature output models available; probe and transmitter have different ambient classesCheck return/outdoor air range rather than assuming rated industrial exhaust service.
ConfigurationIntegral transmitter at insertion probeAccessible placement differs from remote x2000 transmitter.

Engineering selection and installation

The x1000-T is intended for small round ducts and air terminals, with a thermistor node architecture that scales by probe size. EBTRON’s maker documentation stresses proper insertion and location relative to duct disturbances. Duct area, airflow unit (CFM versus SCFM), actual atmospheric/standard density assumptions and local BAS trend scaling should be recorded. In a 4-inch duct a single node arrangement differs from a 16-inch two-node probe, and the stated ±3% installed figure depends on representative flow and manufacturer’s placement guidance. Do not claim AMCA certification where EBTRON’s own performance method differs.
