Home / B-Series Bi-Directional Air Velocity & Air Temperature Sensors
Bi-directional air velocity sensors that output the air velocity, temperature, & airflow direction.


The B-Series is a platform of bi-directional air velocity and air temperature sensors with both analog and digital communication outputs. The bi-directional sensor outputs the velocity and temperature of the air, as well as the airflow direction, in real-time.
Bi-directional airflow sensor to detect flow reversals and directionality.

Detect Flow Reversals & Directionality

Optimized for combustion, curing, process control, clean room, HVAC, and other demanding applications
Airflow sonsor with conformal-coated electronics for longevity in corrosive environments.

Conformal-Coated Electronics

Robust, UV-tolerant, splash-proof design for use in corrosive environments
Choice of air velocity range, supply voltage,  mechanical length, and output communication
Analog & Digital Communication
Supports 0-5V, 0-10V, 0-20mA, 4-20mA, and digital UART or I²C communication outputs
Universal Voltage Supply
Suitable for applications where AC or DC supply voltages are encountered.

Innovative "Outside the Duct" Installation

Single hole for mounting sensor assembly, without the need for screws or hands inside the duct
