Description

The SN-3000-FSJT-NPN wind speed transmitter utilizes a three-cup anemometer principle, where wind rotation generates a proportional pulse frequency. This pulse signal is output via an NPN open-collector transistor, providing a robust digital interface suitable for industrial control systems and environmental monitoring networks. The sensor’s design ensures accurate data collection even in challenging conditions.

Engineered for durability, the sensor housing is made from polycarbonate composite, offering excellent mechanical strength, hardness, and corrosion resistance. The internal bearing system is optimized for minimal friction and long-term reliability. With an operating temperature range of -20°C to +60°C and IP-rated protection (implied by outdoor use), it is built for continuous operation in weather stations, marine applications, and agricultural environments.

Key Features

  • Pulse-type wind speed measurement with NPN open-collector digital output.

Frequently Asked Questions

What is the output signal of this wind speed sensor and how do I interface with it?

The sensor provides an NPN open-collector pulse output. The frequency of the pulses is directly proportional to the wind speed. To read it, connect the output signal wire to a digital input pin on a microcontroller (like Arduino) or a pulse counter input on a PLC, with a pull-up resistor to your logic voltage (e.g., 5V or 3.3V). The sensor's common wire connects to ground.

What is the power supply requirement for this sensor?

The sensor operates from a wide DC voltage range of 5V to 30V, with a low current consumption of ≤20 mA. This makes it compatible with standard 12V or 24V industrial power systems, as well as 5V microcontroller boards, providing significant flexibility for system design and integration.

Is this sensor suitable for permanent outdoor installation?

Yes, it is designed for long-term outdoor use. The housing is constructed from corrosion-resistant polycarbonate composite, which withstands UV exposure and harsh weather. The bottom cable outlet design and sealed construction provide enhanced waterproofing, ensuring reliable operation in rain, snow, and marine environments within its -20°C to +60°C operating range.

How do I convert the pulse output to a wind speed reading?

You need to measure the pulse frequency. The sensor typically has a specific pulses-per-revolution (PPR) or pulses-per-meter relationship defined in its datasheet. By counting pulses over a known time interval, you can calculate the rotational speed and, using the anemometer's calibration factor, derive the wind speed in meters per second. Sample code for microcontrollers is often available to perform this calculation.
