BACnet and Modbus are available only on HTB116e, HTM116e, HTS116e, and HTC116e.
The HTx116-P series is EBTRON’s premium hybrid multipoint airflow and temperature measurement solution for accurate, repeatable airflow measurements in ducts and plenums. Multiple sensor nodes provide precise measurement of critical airstream parameters using EBTRON’s proven thermal dispersion technology. The hybrid transmitter architecture offers flexible connectivity options to support a wide range of HVAC control systems, while advanced airflow and temperature measurement, alarm capabilities, and BACnet® and Modbus® communication options simplify integration into both new and existing building automation systems. The HTx116-P series is ideal for supply, return, exhaust, and outdoor air intake applications.

Sensor Density
Sensor density is designated by the final letter in the model number (for example, HTx116e-PC, where C indicates the sensor density). C density is recommended for most HVAC airflow measurement applications, while alternate densities are available to optimize performance for laboratory measurements, compromised installation conditions, fan tracking, or airflow monitoring applications.
