Duct Air Flow Sensor, RS485/4-20mA/0-5V/0-10V

Description

Duct air flow sensor/transmitter is designed for measuring airflow velocity and flow rate in pipelines, with a high-precision wind speed measurement unit that is sensitive and can quickly and accurately measure small wind speeds. It has good stability, small drift, and high accuracy, and can calculate real-time air volume values based on the measured pipeline cross-sectional area.

Features

• Duct air flow sensor is suitable for harsh environments such as ventilation ducts and grease exhaust ducts.
• The sensor utilizes a full-range secondary calibration method to ensure good linearity and high accuracy.
• Its open flange installation design, combined with high-quality silicone sealing rings, reduces air leakage and ensures durability.
• Users can set the measurement duct cross-sectional area, and the sensor uploads real-time flow values based on the configured area.
• Air flow sensor features an RS485 communication interface that supports the standard ModBus-RTU protocol, with configurable communication address and baud rate, and a maximum communication distance of 2000 meters.
• The duct air flow transmitter address can be configured via software or set using a DIP switch, providing ease of use for the operator.
• The terminal block uses imported tool-free terminals, allowing users to connect with just a simple press and insert, eliminating the need for tools.
• The sensor incorporates specialized EMC anti-interference components, enabling it to withstand strong electromagnetic interference from devices like variable frequency drives.
• It is marked with airflow direction indicators, facilitating straightforward installation on-site and ensuring a simple and efficient setup process.
