"What is the safe wind speed? WSD-E11 wireless anemometer for you"

Q1: What is the WSD-E11?

A: It’s a wireless, explosion-proof wind meter (anemometer). It measures wind speed, direction, and temperature, then sends that data wirelessly to a display receiver. No cables needed.

Q2: Why choose wireless over wired?

A: Wired anemometers need long, expensive cables that can get damaged or be hard to move. Wireless lets you monitor wind from a safe distance – up to 400 meters (or 1300 meters with the XB model). It’s simpler, safer, and more flexible.

Q3: Is it safe for hazardous areas like oil sites or mines?

A: Yes. The WSD-E11 has ATEX certification (EX II 2 G EX ib IIB T4). That means it’s intrinsically safe – it won’t create sparks or cause explosions. It’s the first wireless anemometer in the world with this certification.

Q4: How long does the battery last?

A: The sensor battery lasts 4 years. It uses a single AA lithium battery (SAFT LS14500EX). You can install it and forget about it for years.

Q5: How do I see the wind data?

A: You have three easy options.

First, the included receiver box with a backlit LCD screen and large digits.

Second, your smartphone – with the optional Bluetooth feature and free Windsmart App (iOS/Android).

Third, you can connect it to your own safety system using the 4-20mA industrial outputs.

Q6: Can one sensor send data to multiple displays?

A: Yes. Multiple display units can connect to a single sensor. That means your crane operator, site supervisor, and safety manager can all see the same real-time wind data at the same time.

Q7: Does it have alarms?

A: Yes, built-in. It has a visual alarm (warning lights) and an audible alarm (85–90 dB – loud enough for a noisy site). It also has 4 programmable relay outputs, so you can trigger external horns, strobes, or even auto-shutdown systems.

Q8: What wind range can it measure?

A: Wind speed from 0.3 to 50 meters per second with ±3% accuracy.

Units available: m/s, km/h, knots, mph, and Beaufort.

Wind direction: 0–360° with no dead zone.

Temperature range: -30°C to +55°C.

Q9: Is it tough enough for construction sites?

A: Absolutely. It has IP67 waterproof rating – dust-tight and can be submerged. It withstands rain, dust, and extreme temperatures. The mounting bracket is self-leveling, so you don’t need to perfectly align it.

Q10: How often does it update?

A: The sensor measures wind every 2 seconds and sends data every 2 seconds. You get real-time, up-to-date information constantly.

Q11: What is your biggest advantage over other anemometers?

A: Wireless + ATEX safety + 4-year battery + smartphone app – all in one device. No other anemometer on the market offers this combination. It means safer workers, easier operation, and less cable mess.

Q12: Where should I use the WSD-E11?

A: Perfect for:

Offshore and onshore platforms

Oil and gas industry

Mining industry

Construction sites with tower cranes and hoists

Anywhere wind safety matters and cables are a problem.

Q13: Can I connect it to my existing control system?

A: Yes. It has 4-20mA outputs (programmable: 4mA = 0 m/s, 20mA = 50 m/s) and 4 relay outputs (2A / 24V each). You can easily integrate it with PLCs, alarms, or other safety systems.

Q14: Does it show wind gust history?

A: Yes. The receiver displays a bar graph of wind gusts from the last 2 minutes and an 8-hour history graph of wind speed data. Very helpful for spotting trends.

Q15: How do I get one?

A: Contact us directly for pricing, a demo, or technical support. We supply tower crane accessories and can help you choose the right model (standard 868 MHz or customizable 908/922 MHz).
