Introduction

Scarlet Long Range Wireless Explosion Proof Anemometer Series provide two reliable solutions for hazardous area, WS-E10 ( Explosion-proof Wind speed meter) and WSD-E11(Explosion proof wind speed  + direction meter). Both adopt state-of-art wireless technology and obtain ATEX certification. Scarlet WS-E10/WSD-E11 with high-end design and intrinsically safe feature, make it the ultimate solution to improve worksite safety.

Unlike the existing explosion proof anemometers in the market, Scarlet WS-E10/WSD-E11 stands out for its wireless technology. Operators can monitor the wind condition in safe distance without cable connection. Integration with your own safety system is also feasible via 4-20mA industrial output. Optional Bluetooth connectivity allows users to monitor wind condition in real time on their smartphones by using Scarlet Windsmart App. With all these unique features, Scarlet aims to improve operation safety in all kinds of harsh environment.

 

Intrinsically Safe ATEX approved wind speed and direction combined sensor. First of its kind in the world to provide a state-of-art safety option for hazardous environments.
