Product Image
Product Overview	The Duct Air Velocity Transmitter for Livestock Ventilation is designed for continuous measurement of airflow velocity in poultry houses, pig farms, cattle buildings and other mechanically ventilated agricultural facilities. The system combines a duct-mounted stainless steel sensing probe with an electronic transmitter to provide real-time airflow data for livestock house climate controllers, PLC systems, environmental monitoring platforms and farm automation networks. Installed in ventilation ducts or representative airflow channels, the transmitter helps farm operators monitor ventilation performance, identify airflow changes and support automatic fan or air inlet management. It is suitable for commercial livestock projects where stable environmental control is required throughout different seasons and production stages.
Key Features	Continuous Air Velocity Monitoring: Provides real-time airflow measurements for livestock ventilation and climate control systems. Stainless Steel Sensor Probe: Durable sensing probe offers good corrosion resistance for demanding agricultural and industrial ventilation environments. Streamlined Probe Structure: The airflow-oriented probe design minimizes unnecessary disturbance around the sensing point and supports stable measurement response. Duct-Mounted Installation: Flange-type mounting allows convenient installation in ventilation ducts, exhaust channels and air supply systems. Digital Communication: RS485 Modbus RTU communication supports integration with PLCs, controllers, data loggers, gateways and central farm management systems. Remote Monitoring Options: Wireless communication configurations can be supplied for selected projects requiring remote environmental monitoring. Livestock Automation Integration: Suitable for connecting airflow information with ventilation fans, air inlets and environmental control systems. Weather and Farm Adaptability: Configuration can be selected according to local climate, livestock species, building layout and ventilation strategy.
Structural Components	Air Velocity Sensor Probe: Stainless steel probe inserted into the ventilation duct to detect airflow velocity. Mounting Flange: Secures the probe to duct walls and provides a stable measurement position. Transmitter Housing: Protects signal conditioning, communication and electronic components. Signal Processing Module: Converts sensor measurements into standardized digital or optional remote communication signals. Communication Interface: Enables connection with ventilation controllers, PLC systems, SCADA platforms, IoT gateways or farm environmental monitoring systems. Connection Cable: Provides electrical and signal connection between the probe, transmitter and control system. Mounting Points: Allow secure installation of the transmitter housing on a wall, equipment frame or ventilation structure.
Working Principle / Structural Principle	The sensing probe is positioned directly in the moving air stream inside the ventilation duct. Air passing around the sensor creates a measurable response that is processed by the transmitter electronics and converted into a real-time air velocity value. The measured value can then be transmitted through RS485 Modbus RTU or other selected communication methods to a livestock house controller, PLC, data acquisition system or cloud monitoring platform. In automated livestock ventilation systems, air velocity information can be used together with temperature, humidity, carbon dioxide, ammonia and static pressure measurements to evaluate overall ventilation performance and support environmental control decisions. For accurate monitoring, the probe should be installed at a representative position with sufficient straight airflow and away from severe turbulence whenever possible.

Installation & Maintenance	Select a representative duct section with relatively stable airflow. Whenever possible, avoid installation immediately beside sharp elbows, dampers, fan blades or other structures that may produce strong turbulence. Drill or prepare the required mounting opening according to the selected flange dimensions. Insert the stainless steel probe into the duct and securely fasten the flange to prevent movement during operation. Confirm that the sensing opening is correctly oriented to the airflow according to the installation instructions supplied with the selected sensor configuration. Mount the transmitter housing in an accessible position and complete the power and communication wiring according to the electrical diagram. Configure the RS485 address, baud rate and Modbus communication parameters when connecting to a centralized control system. After installation, verify the displayed or transmitted airflow value under known ventilation operating conditions. Periodically inspect the probe for dust, feathers, grease or other contamination. Clean carefully without damaging the sensing structure. Wiring terminals, mounting screws and communication connections should also be checked during routine livestock house maintenance.
Project Cases	Commercial Poultry Tunnel Ventilation: Air velocity transmitters can be installed at representative ventilation points to provide continuous airflow information to the poultry house climate controller. Pig Farm Environmental Control: Permanent airflow sensors can work together with temperature, humidity, carbon dioxide and ammonia transmitters for integrated environmental monitoring. Livestock Ventilation Upgrade: Existing fan and air inlet systems can be equipped with air velocity transmitters when farms upgrade from manual inspection to centralized environmental monitoring. Remote Farm Monitoring: Wireless communication configurations can support livestock projects where ventilation data must be transmitted to remote management platforms. Large Farm Engineering Projects: Multiple transmitters can be deployed across separate buildings or ventilation zones for centralized environmental supervision.
