Pipe wind speed sensor

Device Name: Pipe wind speed sensor

Pipe wind speed sensor is mainly used to measure small wind speed in HVAC, flue gas treatment pipes, coal mines and various pipe systems.

Functional description: Designed for pipeline wind speed measurement, the independently developed high-precision wind speed measurement unit is sensitive and can quickly and accurately measure small wind speeds, with good stability, small drift and high accuracy. The transmitter can also calculate the real-time air volume value according to the set measured pipeline cross-sectional area.

Detection principle: The wind speed is measured using the hot wire balance principle. The response speed is fast and the starting wind speed is small.

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

Wiring method: The terminal block adopts military-grade spring-type screw-free terminal, which can be connected by pressing and plugging. Even if there is no screwdriver on site, the wires can be quickly connected. It can adapt to wire diameters of 0.3 to 2.0 mm.

Pipe wind speed sensor installation precautions:

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

2. Note that it needs to be installed on the side or bottom of the pipe, and cannot be installed from top to bottom.

3. First, make a hole with a diameter of 20mm on the ventilation duct, insert the air duct into the hole, and adjust the direction of the equipment so that the arrow direction of the equipment is consistent with the direction of the wind speed (the direction from which the wind comes). The height of the equipment can be controlled by adjusting the position of the flange.

Pipe wind speed sensor measurement elements:

1. Real-time duct wind speed

2. RS485 type optional duct air volume value

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 and set the pipe cross-sectional area through 485 commands

2.485 type can provide professional configuration tools to configure equipment parameters

3.485 type can adjust 485 slave station through hardware dip switch

Probe line length: The default line length is 1m, which can be longer or shorter. The longest length can be 100m, but there needs to be no interference around the line.

Pipe wind speed sensor device display:

1. Optional organic light-emitting display, OLED screen with wider viewing angle, self-luminous and low power consumption.

2.485 model can display the current wind speed and related wind volume in rotation.

3. The analog type can display the current range and current wind speed in rotation.
