Pipe wind speed sensor

Device name: Pipe wind speed sensor

Pipe wind speed sensor is used to measure the speed of air flowing through the duct system, providing accurate wind speed measurement.Function description: Designed for pipeline wind speed measurement, the independently developed high-precision wind speed measurement unit is sensitive to the response and can quickly and accurately measure the tiny wind speed, with good stability, low drift and high accuracy.The transmitter can also calculate the real-time air volume value based on the measured pipeline cross-sectional area.

Detection principle: Use hotline balancing principle to measure wind speed.Fast response speed and low starting wind speed.

Calibration method: The full-scale secondary calibration method independently developed by the company is adopted, with good linearity and high accuracy.

Wiring method: The wiring terminals use military-grade spring-free screw terminals, which can be wired with one pressure and one plug.Even if there is no screwdriver on site, the wire can be connected quickly, and it can adapt to the wire diameter of 0.3~2.0mm.

Notes on installing Pipe wind speed sensor:

1.Open-hole flange installation, adopts high-quality silicone sealing ring, with small air leakage and durable.

2.Be careful to install it on the side or under the pipe, and cannot use the top to bottom installation method.

3.First, punch a hole with a diameter of 20mm in the ventilation duct, insert the air duct into the hole, adjust the direction of the equipment so that the direction of the arrow of the equipment is consistent with the direction of the wind speed (the direction from which the wind comes).You can adjust the flange Position controls the height of the device.

Pipe wind speed sensor measurement elements:

1.Real-time pipeline wind speed

2.RS485 type optional air volume value in the pipeline

Signal output: RS485, 4-20ma, 0-5v, 0-10v

Pipe wind speed sensor parameter modification:

1.You can change the device address and baud rate through the 485 command to set the pipeline cross-sectional area

Model 2.485 can provide professional configuration tools to configure equipment parameters

Model 3.485 can be adjusted by hardware dial switch 485 slave station

Probe line length: The default line length is 1m, which can be long or short, and the longest can be made 100m, but there is no interference around the line.

Pipe wind speed sensor device display:

1.It can be equipped with an organic light emitting display, with a wider viewing angle, self-luminous and low power consumption.

The 2.485 type can wheel display the current wind speed and related air volume.

3.The analog quantity type can wheel display the current range and current wind speed.
