Analog wind direction sensor 3S-WD-I-P

analog output4-20 mAwith electrical output signal

Product overview
The 3S-WD-I-P is a plastic wind direction sensor designed for industrial monitoring, PV plants and weather stations requiring a compact, UV-resistant unit with a standard analog output. It delivers wind direction from 0° to 359° with ±1% accuracy and 0.1° resolution, and is supplied ready-to-mount with cable and fixing hardware.

Key features

• Item code: 3S-WD-I-P
• Analog output: 4–20 mA for easy integration with PLC, SCADA and dataloggers
• Accuracy & resolution: ±1% accuracy, 0.1° resolution
• Measuring range: 0–359°
• Outdoor-rated: UV-resistant ASA housing and weatherproof cable
• Low consumption: typically 30 mA @ 24 V DC
• Supplied with mounting hardware for pipe or ground installation

How it works

• Wind rotates the vane and shaft.
• A magnet on the shaft passes a Hall Effect position sensor.
• The Hall sensor determines angular position (0°–359°).
• Onboard electronics convert angle to a 4–20 mA current-loop signal for connected controllers.

Installation

• Install in an open location clear of obstructions that disturb airflow.
• Align the sensor N-mark to True North for accurate directional data.
• Mount on a vertical pipe or support arm using supplied corner-head bolts.
• Connect the 4–20 mA output to the analog input of PLC, SCADA or datalogger and scale accordingly.

Maintenance

• Perform periodic visual inspections following IEC 61724-1:2021 guidance.
• Remove debris or bird droppings and verify free vane rotation.
• Re-check alignment after mast movements or servicing.
