Wind Speed Sensor

Device name: Wind Speed Sensor

Wind Speed Sensor is an industrial grade detector that can monitor wind speed in various types of duct environments and is a low cost duct anemometer.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 are military-grade spring-free screw terminals, and can be connected by one pressure and one plug.Even if there is no screwdriver on site, the wire can be connected quickly, and can adapt to the wire diameter of 0.3~2.0mm2

Notes on installing Wind Speed Sensor:

①.Installation of open-hole flange, high-quality silicone sealing ring, small air leakage, and durable;

②.Pay attention to installation on the side or under the pipe, and installation method from top to bottom cannot be adopted.

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 arrow direction 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.

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

Parameter modification: ①.The device address and baud rate can be changed through the 485 command to set the pipeline cross-sectional area; ② and 485 types can provide professional configuration tools to configure equipment parameters; ③ and 485 types can adjust the 485 slave station through the hardware dial switch.

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.

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.

②.The 485 type can display the current wind speed and related air volume.

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