Pipe type anemometer transmitter

Device Name: Duct Type Air Velocity Transmitter

The pipeline wind speed transmitter is also called the pipeline wind speed sensor. The pipeline wind speed transmitter is designed for pipeline wind speed measurement. The self-developed high-precision wind speed measurement unit has a sensitive response and can quickly and accurately measure small wind speeds with good stability. , small drift, high precision.

Function description: The transmitter can also calculate the real-time air volume value according to the cross-sectional area of the measured pipe.

Detection principle: adopt the principle of hot wire balance to measure wind speed. 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 terminal block 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 wire can be connected quickly, and the wire diameter can be adapted to 0.3-2.0mm.

Precautions for installation of pipeline wind speed transmitter:

1. Open-hole flange installation, 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 transmitter 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 transmitter 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

2.485 type can provide professional configuration tools to configure device parameters

3. The 485 type 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, and the longest can be 100m, but there is no interference around the line body.

Pipeline wind speed transmitter equipment display:

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

Model 2.485 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.
