Air Velocity Transmitter

4 products

Air velocity transmitters continuously monitor airflow rates and provide real-time data for building automation systems, ventilation controls, and energy management. They are equipped with high-sensitivity sensors and robust designs, ensuring long-term accuracy in industrial, commercial, and laboratory environments. By integrating these transmitters, users can optimize HVAC performance, reduce energy consumption, and maintain healthy indoor air quality.

Frequently Asked Questions

Handheld meters are for spot-checks, whereas transmitters are permanently installed for continuous monitoring. HK Calibrations provides these units to send real-time airflow data (via 4-20 mA or 0-10 V signals) directly to your Building Management System (BMS) for automated control.

This thermal sensing technology allows for high precision even at very low air speeds. HK Calibrations recommends these transmitters for sensitive environments like cleanrooms and laboratories where maintaining exact, minimal ventilation is critical.

Yes. Many of our transmitters feature adjustable mounting flanges and field-selectable ranges. HK Calibrations offers these versatile models so a single unit can be calibrated and installed in various duct environments, from small exhaust pipes to large ventilation shafts.

Modbus allows the transmitter to communicate digitally over a network rather than using traditional analog wires. HK Calibrations supplies these for "Smart Building" projects to provide more detailed dataincluding temperature and flow status over a single connection.

A built-in relay allows the transmitter to act as a safety switch. HK Calibrations provides these versions so that if airflow drops below a safe limit, the unit can immediately trigger an alarm or shut down a heater to prevent system damage.

Thermal sensors can drift due to dust buildup or electronic aging. HK Calibrations provides traceable field or lab calibration to ensure your automation system isn't overworking fans or compromising air quality based on inaccurate readings.
