Air Flow Sensors: Precision Measurement for Industrial Ventilation and HVAC Systems
Air flow sensors, also known as airflow transmitters, mass flow meters, or thermal dispersion sensors, are critical components for monitoring and controlling air movement in industrial environments. These devices measure parameters such as air velocity (m/s), volumetric flow rate (m³/h), or mass flow (kg/h), often using thermal, differential pressure, or vane anemometer principles. Key technical specifications include measurement range (e.g., 0-10 m/s or 0-1000 Pa), output signals (4-20 mA, 0-10 V, Modbus RTU), accuracy class (typically ±2-5% of reading), and operating temperature range (-20°C to +70°C). Many models feature IP65 or IP67 protection for harsh conditions, with options for duct or pipe mounting.
These sensors are deployed in HVAC systems for building automation, cleanrooms requiring laminar flow control, industrial exhaust and fume extraction, compressed air monitoring, and environmental chambers. They integrate seamlessly into PLCs, SCADA systems, and building management systems (BMS) via analog or digital interfaces. Common applications include filter monitoring, fan speed control, and leak detection in pneumatic networks.
Our portfolio includes subcategories such as thermal mass flow sensors (e.g., model series FTM-1000 with Modbus RTU), differential pressure airflow transmitters (e.g., series DPT-200 with 4-20 mA output), and vane anemometer probes (e.g., series VAP-500 with telescopic handle). Article codes typically follow a pattern like "AFS-XXXX-YY", where XXXX denotes measurement range and YY indicates output type (e.g., "AFS-1000-4M" for 0-1000 Pa with 4-20 mA). We also stock compact inline sensors for duct diameters from 50 mm to 300 mm.
Partnering with Electric Automation Network ensures access to real-time pricing, global express shipping, and dedicated engineering support. Our specialists assist with sensor selection, calibration requirements, and integration into existing control architectures. We provide detailed technical datasheets, wiring diagrams, and application notes for every article, reducing commissioning time and ensuring reliable operation.
