Pipe type anemometer

[equipment name]: Pipeline wind speed sensor

The pipeline wind speed sensor is also called the pipeline wind speed sensor. The pipeline wind speed sensor adopts a high-precision, low-offset thermal sensor, which is designed for pipeline wind speed measurement. The self-developed high-precision wind speed measurement unit has high precision, corrosion resistance, High long-term stability characteristics.

[Functional description]: Designed for pipeline wind speed measurement, the self-developed high-precision wind speed measurement unit is sensitive, can quickly and accurately measure small wind speeds, has good stability, small drift, and high precision. At the same time, the transmitter can calculate the real-time air volume value according to the measured pipe cross-sectional area.

[Detection principle]: The wind speed is measured by the principle of hot wire balance. The response speed is fast, and the starting wind speed is small.

[Calibration method]: Adopt the full-scale secondary calibration method independently developed by the company, with good linearity and high accuracy;

[Wiring method]: The wiring terminal adopts military-grade spring-type screw-free terminal, which can be connected by pressing and inserting. Even if there is no screwdriver on site, the wiring can be quickly connected, and the wire diameter can be adapted to 0.3-2.0mm2

Precautions for installation of duct type wind speed sensor:

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 pipe, insert the air pipe into the hole, and adjust the direction of the device so that the arrow direction of the device is consistent with the direction of the wind speed (the direction of the wind). The position controls the height of the device.

Pipeline wind speed sensor measurement elements:

①. Real-time pipeline wind speed;

②, RS485 type can choose the air volume value in the pipeline;

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

Pipeline wind speed sensor parameter modification:

①. The device address and baud rate can be changed through the 485 command, and the cross-sectional area of the pipeline can be set;

②, Model 485 can provide professional configuration tools to configure equipment parameters;

③, Model 485 can adjust the 485 slave station through the hardware dial switch.

[Probe line length]: The default line length is 1m, it can be long or short, the longest can be 100m, but there is no interference around the line body.

The ducted wind speed sensor device shows:

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

②, Model 485 can display the current wind speed and related air volume in rotation.

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